Home Assistant: Cheap multi-room Temperature Sensors (Xiaomi Mijia BLE ESP32)
HTML-код
- Опубликовано: 11 окт 2024
- I have been using the Honeywell Evohome system in our house for multi-zone underfloor heating since it's we've moved in. I've also been having issues with this system since that time and it's cost me a lot of work to get it to do what it should do and I'm really fed up with it!
This video is the first step into replacing that system! In this video we're going to set up an easy to configure and cheap multi-room temperature sensing system with Home Assistant at its heart.

This is amazing. I followed your instructions and now my hassio picks up measurements from 5 xiaomi devices on a single esp32. I'm looking forward for the video about making graphs in grafana. Keep up the great work 👍
Back again to remind myself how to add additional esp32s and sensors. Went smoothly thanks to your clear instructions. Holding the boot button was a very useful tip.
Thanks!
amazing sensor , i been using 6 of this sensors simultaneously for over 1 year now to control my heating Baseboards on hassio with rpi3b (built-in BT ) /sonoff POW tasmoted (built-in BT ) with no problem , i noticed the RPI is a lil slower with this setup , i now want to migrate on a vm on proxmox , thx for sharing
What a great vid, I was able to follow along and get the same temp and humidity sensor working from scratch with no prior knowledge of esphome. Greatly appreciated.
Awesome video! It is exactly my case, but using aerothermal. The installation of the system I have scheduled for mid-July 2019, and I wanted to put the Evohome system, but after watching your video I think I will not do it!
I can't wait to see the next part to see how you control the collectors domotically.
Thanks!
Hello, i am from Germany and my english is not very good, but how you are speak in the videos i can understand good. thanks for helping me with my BT Sensors and maybe other Problems/Solutions/ideas for HA. you got now my subsciption... oh .. and i dont forgot to hit the bell
Greetings from Black Forest Germany
Great video. For those that want to jump straight to the how-to, it starts at 3:40
Content starts at the beginning.
@@tomtreacy1545 Updated comment to be more accurate :)
Thanks Just got the ESP32 Uploaded HAD to put finger on the boot switch worked now want the Other bits to come thanks. for taking the time to make this.
Great video, I'm about to give these sensors a shot - I'm pretty much in the same shoes with the multi-room heating thing. Subbed, keep up the good work!
Great video! Based on this I was finally able to integrate my Xiaomi plant sensors again. Moved Home Assistant to a VM and lost the Bluetooth capability. Will get some of the room sensors as well. Thanks again for the inspiration.
What did you do to get them working? I'm using my plant sensors for room temps at the moment but keep running into the 10 second timeout bug
The ESP32's are on their way. I usually preconfig ESP8266 on a cable with my HA pi. Works great. Another great vlog BTW. Looking out for part 2.
I have evohome with 8zones for over 3 years now and monitor it using domoticz/grafana. It is striking to see there is virtually no pid control, just on/off even on a eurotherm connection. Overshoots of 2 degrees are quite “normal”. It seems to me it shouldn’t be too difficult to mathematically model the zones and provide a sensible setpoint to the heating system. I certainly would welcome a pid alternative approach to evohome’s software and could help with the model.
Love your work.
Keep it up.
Can't wait for the next video!
you make it all look so easy, thanks Qundor!
OMG! 😆 I have the same experience with some crazy Indian technicians. Except it was in industrial setting.
The evohome system is definitely far from perfect. In my case I've actually done something that honeywell said was impossible, I've got 2 separate heating systems with 2 separate boilers (1 for the heated floors, one for the regular radiatiors in the other sections of the house) and I actually got it working with a single evohome.
WoLpH I definately would like to learn more about your solution. I have 2 independent heating systems, domoticz can talk to them
In the end the setup is actually quite simple, it just took some trial and error to get it working.
The first boiler with the radiators is setup as a regular evohome system.
The second boiler is connected to the evohome as a Mixing Valve Controller (but it's physically just a R8810 OpenTherm Bridge) with a DTS92 thermostat as temperature sensor (and temperature control).
That surprisingly works effortlessly for me :)
The only problems I've had with the system is the occasional temperature overshoot/undershoot when the weather changes a lot in a short time. And I had to add a bypass conduit to my main boiler because the pump would crash otherwise.
an excellent introduction to ble gateway. cheers
Great stuff, exactly what I was looking for. This combined with sonoff main heating switch, bluetooth trvs gives me zonal HA controlled heating.
Many thanks. :)
Thought this was a good addition to my Home Assistant. Bought 4 sensors and esp32 board. Followed blog post and video. Works good for me!! One snag I ran into (being in the US) is the Sensors themselves only display in Celsius. Home Assistant takes care of displaying in Fahrenheit so no big deal.. Bought 4 sensors to start. Buying 4 more soon.
How would I get the esp32 boards to "mesh" if I need them too?? That wasn't covered in the video...
Great you like it, I still use it too and it works great! The ESP32 don't need something like a Mesh since they use WiFi?
Best interessant die wandcontactdozen op de buitengevel!
Salut IT600 solved my problem :) . Cannot be integrated in HA tho, but in theory once you set up the heating there is no need for user intervention again.
Great video. Do you know if this will work for the new generation square version Xiaomi Mijia sensors?
I use the same method. Also had problems with older soft.
Hi - many thanks for the great video.
I was able to set this up using your blog and the video. However, the frequency of the readings appears quite low. Is there a way of increasing it. In the logs of the esp there is a whole lot of scanning
I also find the distance between device and esp was pretty small, particularly if there is a wall in between. In the logs I noticed a statement which said 'Tx power: 2" - can that be controlled and if increased will it improve the connection distances?
Your assistance is much appreciated.
Great tutorial! I was able to get it work with one esp32 board in my bedroom.
However, I want to be able to place the xiaomi sensor anywhere in the house, so I reuse the sensor in the second esp32 in living room. but the sensor in home assistant can only be updated via the bedroom esp32.
I guess it's the limitation of home assistant. maybe I should use two different name and merge them in home assistant using template sensor instead?
Ah yes, while toying with it I ran into this too. I deleted the entity from the Home Assistant database and after that I was able to move that sensor to another ESP32. I had hoped it could be done seamlessly, but something in Home Assistant is blocking that.
That's the reason why I have totally forbidden any plumber to make a step into my house, so i built up the heating all by myself.
It doesn't matter if it is honeywell or Siemens, viessmann... They all want your best... Your money :)
Is that the best temp sensor to buy i.e Your Mija one, i noticed they have a few Xiaomi temps sensors now?
Can you use bluetooth of the Raspbrerry Pi instead of the ESP module?
Seems it can: www.home-assistant.io/integrations/mitemp_bt/
But I think only with one sensor.
@@aidanearl You can repeat entries in the config file. They have names on them for that reason.
@@PipsTube oh thanks. I found that it often lost connection so I set up my ESP module and that is a lot more reliable.
Thank you for sharing!
I have done everything as shown. I can see in esphome flasher that it is connected to wifi, the mac address and the measurements from the sensor. Also, it shows online in esphome. Although, it doesn't show logs ('' WARNING Initial connection failed. The ESP might not be connected to WiFi yet (Error connecting to 92.242.132.16: timed out). Re-Trying in 1 seconds'') not even connecting through configuration.
Any idea?
Excellent video! I would like to keep tracking of my refrigerator and freezer temperature. Is there a temperature sensor that you know for implement on this?
Great tutorial! Is this still the best option?
Mooi huis! Bedankt voor je informatieve youtube filmpje.
That's great idea, thank you. Keep up that god job
Great Video. Does this work with the zigbee t&h sensor?
Great video. I really like your work! Can you please give me feedback after one year of using the sensors? do you still use this solution? did you try with e-ink display? Thank you
There is an update video already and a new one coming soon. Short version, still use them and very happy with them!
@@IntermitTech I will want to but some sensors for the exact same scenario. witch one do you recommend? did you found a solution for a thermostat that will work with home assistant? thank you PS: just wait for the new video! make it faster, the winter is coming! :)
Great videos, thanks! Did you look at Homematic for your heating control? I considered the Evohome, but realised that it couldn't everything I wanted and now I have Homematic-IP thermostats and TRVs. It works great, and I believe there is support for under-floor heating as well.
I hadn't heard about that brand, I'll look into that! Mind you, this system was built in 2016 so probably newer stuff is available. :)
--update
Their stuff looks really nice! That wasn't available yet when I was looking for it, quite sure of that. Still going to continue my Home Assistant route though, I like having it open and flexible (being in a blackbox closed system now).
Yes, I like that it does wireless and wired as well. Integrates well with HA as well, the only negative is the web interface sucks, especially setting heating/cooling schedules. However, I have a large living area with 3 radiators and parts of the room were either too hot or too cold. With Homematic it keeps the temperature the same overall.
I use the Xiaomi Aqara Temperature Humidity Sensor which are even cheaper and work via ZigBee. They don't have a nice display though. But that's okay for me. The only thing about your video that is still not clear to me, is how these sensors manage to heat/cool a specific room. How did you connect that and to what did you connect it?
Hi! I discovered this video searching about heating floor smart system and I was thinking in the same idea to make a multiroom thermostat. I have not wait to watch your project ended. My house has some rooms and some valves to each one. I was think to make a temperature/hum sensor per room and a separate relay per valve but I don't know how to code in home assistant to show it like a thermostat to can made programs a change temperature individually.
I'm still working on this series but other projects have a bit of priority, will return to it in the future though!
interessant. Vervanging voor EVO home? link please. Alvast bedankt
Nice work!! Thx for sharing, helped me out 😁
Thanks for the video. Really good instructions. I have one question. Say that I have a Dig-Uno with an ESP32 that was flashed using the wled firmware and now I want to also include the Temp/Humidity sensor. By flashing it again the wled will be eliminated and the functionality lost, right? How can I add the read-Bluetooth-info-and-send-it-to-mqtt that is so nice to have without affecting the wled which ... is also so nice to have 🙂
Thank you and keep up the great work.
Sorry, you won't be able to do that with WLED. Running ESPhome it can work.
@@IntermitTech alright. Thank you for the quick reply.
you could've got xiaomi zigbee sensors which goes for 9$ each and that size of wrist watch (no display) connect them to a zigbee adapter (conbee/usb or raspbee/onboard)
this will let you monitor/control/automate more devices with very low power consumption
Hello from Argentina, first of all great video!! .... I have a question, after setting all this up, would be possible to link Home assistance with google home and see/control the xiaomi's sensors directly in google home app?
Really neat solution!
I wonder how are you planning to control the underfloor heating since it has very slow reaction time? I have the same problem and I haven't come up with a decent algorithm yet...
pid control logic.
I've just gone through a bunch of your videos. Great, great, great content in an era of bad content on YT. Thanks!
Just a quick question. I have a intell compute stick with bluethoot on it....can i manage to get those without esphome?
Do you have any video on how to start using the esp? im really interested in getting these sensors but i wanna know how to get them integrated in HA from the first step to the last.
I've enjoyed watching some of your videos. Thank you. One thing...turn down that dang audio on your intro! Hopefully I'm not the only one who thinks so. 😁
very nice I will get one to test :)
Did you also checked the zigbee protocol with Xiaomi sensors etc. using zigbee2mqtt?
Awesome tutorial and blog, worked like a charm. Set it up in 10 min !!
Awesome tutorial! Just one quick question, is it possible to use ESP32 with Xiaomi Bluetooth Gateway? Like both query the data from the sensors at the same time.
I haven't tested it but I think it will work since the sensors just broadcast their information
get job keep up the good work
Nice, I was trying to get this working on tasmota, but was having issues using it with ibeacon/itag devices also. Anyone using esphome with xiaomi and itag devices form a single bridge?
It would be so much more easy to just get the Xiaomi Gateway, the Xiaomi Mijia Bedside Lamp and the temperature sensors. the reason why I say that. is because the gateway adds nicely and easy to Home assistant the along with everything added to the gateway. the bedside lamp doubles as a Bluetooth bridge between the Gateway and the temperature sensors. so it should report the temp and hum into the home assistant. hasslefree. I'm going to test this doing the summer
Any reason you didn't just use the Xiaomi zigbee sensors? It sounds much easier.
I'm not aware of any nice (and affordable) zigbee sensors that include a display. There's the Xiaomi Aqara Temperatue and Humidity Sensor: xiaomi-mi.com/sockets-and-sensors/aqara-temperature-and-humidity-sensor/
But there's no display on that unfortunately.
Is there a way to make the LED on ESP32 blink each time it receives any telemetry data from the MiJia units? I am not sure how to code it in esphome.
Did you consider using the other Xiaomi temp and humidity sensors that work with their gateway/hub? It would avoid the need for the ESP32 boards. Admittedly they don't have the LCD display so are aren't a like for like replacement.
Ah no, I did not try those. I liked the design of these and since I have ESP32's all around the house anyway (for my lighting system) it was ideal!
Hi, can I flash the nodemcu without esphome via home assistant? Is there a repository with the images or the .ino files? Thankyou (my HA version has not the supervisor entry in the menu and I cannot change distibution.
Thanks for your video which is good quality. One question... I bought 4 of these, assuming that my Raspberry Pi 3B+ which runs Hass.io could use its own Bluetooth interface to gather the different values from the Mijia sensors.
Is there any way to configure that in Hass.io, without the use of a separate ESP32/powersupply/case/config etc ?
I believe that's possible, but I haven't used it so don't really know know how. Maybe some other guides online?
Hello all,
Do we have any idea on the power consumption of the ESP Home, Home assistant server ? I would say like 5W for the Rasp and the esp i suppose near nothing
Is there any way to change these from celsius to fahrenheit. Everything I'm seeing so far says no.
Good job. Would it be possible to tear down the Xiaomi device and power it directly from the ESP32? (Without the load of the screen it shouldn't need much power.) [I know that would not work for your application, where you want to measure each room and minimise the number of ESP32 devices.]
No, that's not going to fly. The AAA battery is 1.5v and the ESP32 needs 3.3v or 5v for the whole development board. So you'd then need to add a DC-DC converter but at that point, what kind of frankenstein solution are we building. ;)
I use these directly with Home Assistant and a LM1010 class 1 bluetooth USB dongle with a good result in a small house. I never had any luck with BLE and ESPHome but is that fixed now? (and thanks for the great videos)
It's been running stable for me for the past few weeks, OTA updating has also been fixed! :)
👍
can you use the builtin bluetooth of the Raspbrerry Pi instead of the ESP module?
yes you can...according to this guide: flows.nodered.org/node/node-red-contrib-xiaomi-ble
Interessante video !!
3:30 this needed to be said loud - DHT22 are not that great as people want us to think. Not that reliable and integrating them into MCU systems is a pain, mostly due to wacky sub-milisecond delays.
Hi there. I have brought two sensors and 2 ESP32 Development Boards. I have copied the Sketch and flashed to the board using NodeMCU PY Flasher as ESPEasy would not work for flashing. NodeMCU flashed and said it had successfully uploaded the file. During the flashing process the RED LED on the Esp32 Dev board stayed RED and no other LEDS were on, however it appeared that the flash was successful.
After unplugging the USB cable from the Windows Computer and plugging the ESP32 Dev Board into a 5v Phone adaptor, the RED LED came on again (No other LEDs on) and it has not connected to Wifi. In ESPHome the File is Still showing as OFFLINE and all my other ESPHome devices are GREEN and connected as normal.
This is the Top section of the Code - esphome:
name: bluetooth_esp1
platform: ESP32
board: esp32doit-devkit-v1
I also tried a seperate sketch using different board type with this code on a second ESP32 Dev Board and same result, NOT Connecting after a successful flash
esphome:
name: xiaomi_bluetooth
platform: ESP32
board: nodemcu-32s
Any ideas on what could be wrong would be great appreciated as I am so keen to get these Xiaomi working. Thanks for your help in advance
When using multiple ESP32's to cover your whole house, do you put the same sketch on all of them? By this I mean, if you add the MAC addresses on all the ESP32's or only to the one closest to the sensor?
I tried using the same Mac addresses on all of them but it seems Home Assistant got confused by that so then I switched to basically appointing an ESP32 to which a sensor will connect and that's worked well so far.
@@IntermitTech Alright, thanks for the reply!
Hi. I am not getting any Serial Ports available on the drop down when using esphomeflasher. Any ideas?
I was wondering if you could give me some advice. My ESP32 i thought was working great with the same Mija temp/humidity sensors as in video. Works great for about 24-48 hours. Then i check HA and see no activity for 12 hours and wondering why my heating hasn’t turned off - this is why.
Have you had the same problem, if so, how did you fix?
Yes, I have a few running and most run fine, but I've also seen the same behaviour you are seeing. I'm not sure yet why this happens (probably bluetooth code isn't fully stable yet) but as a workaround I've implemented a reset every night of those ESP32 modules. Not pretty, but it works for now. I will make a video update about that in the future, but I want to include more in that video and that isn't ready yet.
For now you could add the following code:
time:
- platform: homeassistant
on_time:
- seconds: 0
minutes: 0
hours: 4
days_of_week: MON-SUN
then:
- switch.toggle: restart
switch:
- platform: restart
name: "test_temperature Restart"
id: restart
That should restart that ESP32 module each night at 04:00. Let me know if that helps you please. :)
Intermit.Tech Wow that’s exactly the answer I was hoping for! Thanks very much all the way from Ireland. Really enjoyed this video.
:) system is too stupid (2:00) you are star mate! I like your channel. I'm building my own system now ... well copy your stuff but yeah :)
@10:16 specifically you show two boards that aren't listed in your description, you describe only as "quin" boards. What are they and where can we get more more information?
disregard, I missed the LED in QuinLED and have found them, a link in the description would be handy. These look VERY interesting, I wish I'd known about these before! Great video, am currently checking out your channel!!! +thumbs!!
Ah, my bad! Those are QuinLED LED dimmer boards, you can find more info about them on quinled.info or take a look at this video ( ruclips.net/video/Sd77zavUyjM/видео.html ) which shows some usage examples!
@@IntermitTech Thanks, I got sidetracked on some of your other vids, Have been watching DrZ's for a while (although not of late), you've just earned another sub! Great work and I think you've convinced me to convert from OH to HA!
If you have multiple ESPHome receivers for Multiple Mijia units, do I flash all of the ESPHome receivers with all the same MACS address on all Mijia units? Since I not sure which ESPHome will receive which Mijia reading.
What I do is I pick one that is in range. Using the same MAC on multiple works for ESPhome, but Home Assistant doesn't understand them with the same name. I have seen others who aggregate the data received by all and then use that aggregated object, but it's a bit complex in my opinion.
Did you consider using NodeRed?
I will in the future, now that all the data is going to Home Assistant I can use it in Grafana and Node-Red no problem!
Your microphone is cool, what make and model is it?
It's a Neat Bumblebee, I did a video about it here: ruclips.net/video/Iq1UoeuOYr0/видео.html
Intermit.Tech Thank you, they reminded me of the Bang & Olufsen earset2 design. For some reason I kept associating the image of the microphone displayed in the Video to a B&O design. The conflict in my head though was that an intelligent person like you would not waste your money on stupidly expensive stuff just for looks and design.
I have one heated room and an opentherm gas heater with a round wireless Honeywell thermostat. How do I connect this to Home Assistant?
top kanaal btw
Do you have an update after almost a year of this video??
I am interested in know the battery life of the sensors and how well when with your problem!!!
Thanks
I'll be doing more videos on this topic soon, but battery life has been good, most sensors where able to last up until now without too much issue. :)
I have few Xiaomi with hassio, working great, but as I am in the us I am annoyed by the display only showing in C not being able to change to F, (no problem with hassio as I just convert it, i an just talking about the LCD display). Anyone with a way of changing this?
When I do the scan this all I get. There should be information for temperature and humidity correct?

Yes, but there seem to have been changes to how it works in ESPhome. Now it won't display that data anymore until you add them. Best to just add them with a generic name and then override the name in Home Assistant to where it goes. :)
Anyone know how to make the readings of the sensor in home assistant update more often? My humidity sensor is only updating every 40 mins or so.
I follow all your video but when since the ESP32 is on all night, I still not getting any telemetry from the mini square MiJia. I see only unknown for all sensors but ESP32 signal is okay.
Try connecting to the sensors again with your phone and spamming "mi like" a few times
@@IntermitTech Maybe I did not remember on the video you mention need to clicked the Advertising type: Mi Like. It works now. Is there a way to get the bluetooth signal of each MiJia unit so we can see how far to place the unit before not receiving it. Thanks a lot. I

Having the exact same problem, the ESP32 is not reading the data from this E-paper type xiaomi sensor. Already found a workaround?
@@royteunissen4004 nope so far.
Can the temperature change to FAHRENHEIT?
Sadly on these meters no. You can do an easy conversion in Home Assistant but the meter will always display celcius.
Does anyone know the difference between this and the Aqara. As the Aqara has wifi out of the box that would seem like an easier set up?
isn't home assistant requires you to different dongles to make it work?
No, in this case you can just use one or more ESP32s which connect over WiFi to Home Assistant. The Xiaomi sensors connect to those ESP32s and translate the BLE temperature data and send it to Home Assistant. That way, no matter how big your home is, you are not stuck to having to use dongles or multiple base stations!
Why does the ESP32 is showing "UNKNOWN STATUS". I had to power cycle ESP32 Devkit.
Can I use one of this sensor out of my home in the greenhouse at aprox. 30 Mt from my home please ? thanks a lot
30 meters would be a bit much for the bluetooth I think. But if you get WiFi coverage there you could place an ESP32 close to it and relay it to Home Assistant that way.
@@IntermitTech Thanks a lot... but I'll go to study the RF433 modules.
I just buy one of this sensor in the Xiaomi Mi shop and I just tested it... well if I don't have a wall, it make about 7-8 Mt
If I have 10 cm of wall between sensor and ESP32 it don't work. (new battery inside)
Can you penetrate a wall with one of this sensor please ?
Thanks again
I have a few that are through several walls even? Also one that I have 7 meters and a wall away! No problems.
@@IntermitTech Strange... maybe my ESP32 have no so good receive.
The problem is that I need about 8 or 9 sensors in order to cover my house, greenhouse, chicken coop etc...
Now I just study in order to make a sensor by DIY with the RFM69 chip and low power consume.
Then... I'll put a sensor also in may bed :-)
Thanks a lot
Why not just use a xiaomi aqara temp/humidity sensor?
Why didn’t you throw some sonoff th16 and avoid all the hassle ?
I don't see what you are saying. :S With those I'd need a power supply in each room and don't have a local read-out? Now I have 14 of these Xiaomi sensors through the house, battery on those WITH screen last well over a year and I have 2 ESP32's in places where I have wiring anyway. They are factory calibrated and only cost about 10$ each, how is that MORE hassle then having to power a device per room which I'll have to hide somewhere? Maybe I'm missing your point?
Intermit.Tech I’m sorry I misunderstood your video , I thought you needed 3 components for each room . Your projects are awesome . I’m trying to repurpose and Arduino mega with internet shield connected to 8 relay board onto hassio and HomeKit functionality , I still don’t understand mqtt that well so i will keep trying . Have a great Sunday
@@EstebanBurneo Aaah, ok, no no, I wanted to minimize the components I needed, especially in all the rooms! Now I just have two central ESP32's (which I had anyway because of my DIY lighting) and the rest are battery powered wireless sensors. :)
But tinkering with stuff is always fun! Hope you get all your relays working! :D
Is there any way to boost the range of esp32? It seems that I wll need one in every room.
Really? Do you have lead walls? ;)
Only way I can think of is using a ESP32 with an external connector, that could enhance range. :)
@@IntermitTech yes houses here in Greece use hard material even to separate rooms. The nearest sensor updates every some seconds but the other two i use in the two bedrooms may update every hour or so. Excellent video by the way.
You’ve had me @ “you need 2 thermostats per room”. Heating in holland per room is quite difficult. Why? It’s not rocket science.
Kjeld Schouten ok indeed, heating is not the problem, but heating or cooling (what’s that?) the way you want. Is to hot, or to cold. At least thats the issues i have.
I've connected the ESP32 board to my Windows 64 PC via a USB cable but when it comes to flashing the firmware ( at 8:04 in the video ) , I can't select anything for the Comm Port as it's blank. What am I doing wrong? I download the ESPHome-Flasher-1.3.0-Windows-x64.exe
file from github.com/esphome/esphome-flasher/releases.
Check in device manager if the COM port shows up, sometimes you need a driver for it.
@@IntermitTech Thanks for the quick reply.
When I plug in the unit to my USB port, it does appear under devices as "CP2102 USB to UART Bridge Controller" but says there's no driver installed. Asking Windows to search and install driver automatically comes back with "No driver found".
I went to www.pololu.com/docs/0J7/all#2 and downloaded these and tried to install the driver manually but it says "Windows could not find any drivers".
In Windows Control Panel, the COM1 port shows as being fine.
EDIT: Nevermind. Got it working. I installed the drivers from:
www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers
I'll leave this here in case others have issues.
Now to complete the setup. Happy New Year.
I re-uploaded OTA and now I see my BLE sensor in HA as sensor.name_2. Not sure what step I missed. How do I prevent sensor names with _2.... _3 and so on whenever I use OTA update?
I haven't had this happen to me, I'll do some checking when I can.
BTW, Xiaomi is pronounced ‘shao-mee’. I get as non-Chinese speakers it’s hard to correctly pronounce it with the tones, but that’s pretty close for us. :)
Yeah, I know I butcher it but my attempts to correct myself never stick. :P
Is there a way to manage the scan interval? I used the scan_inteval code but I get an error that this function was removed.
Even if you could, you are limited by how often the device broadcasts, so what use would it be? Besides, in my experience, with changing values, it update quite often
@@IntermitTech that is the reason. They update quite often and the home assistant database is constantly growing.
@@Κάκαλος But Home Assistant throws away values after 1 or 2 weeks I believe? It's a setting you can set, then it should be no problem! :)
Where is part 2?
How do you plan to control each value?
What I have currently as a test setup is measuring the temperature using the Xiaomi sensors and feeding that into Node-Red using Home Assistant. There I have set rules which check if the heat pump is heating or cooling and then based on that either open or close a valve for the underfloor heating system. I don't have it hooked up yet, but in testing it's been working pretty well.
For the valves the underfloor heating system I made a different video about cheap relay boards!
@@IntermitTech can you link the video to the underfloor heating 😀
Dont some values use PWM?
@@andreasscholdan8087 Well, I have the setup installed yet, but there is a video about relays in my Home Assistant playlist and also check out my "Bathroom ventilation" video which also has more info towards the whole solution! You can find them here: ruclips.net/p/PL4b74vD-Uo-NhFmZoQIIV4I_jI9I23jh1 (video 6, 7 and 8)
@@andreasscholdan8087 For underfloor heating systems? No, generally they are on/off valve systems. The heat source (in my case a heat pump) determines the water temperature as a whole and that then flows to the rooms requesting heating/cooling at that moment and close when that need is satisfied.
