Love the IOT done better line of videos, always providing inspiration for further upgrades at the home!
There are so many reasons why this is wrong. You are wrong. Wendell is also wrong. IoT is wrong. Just pay attention to L1 show of links to share with your friends, there's a pattern repeating itself. In the long term it will be " No matter how hubristic ( a word i just invented ) or rightcheous you are now, corrupt open source library {thanks Micro$oft} will put you in your place at any unspecified point down the road".
HVAC engineer from Belgium here.
Heating/cooling and ventilation in homes here are mostly separated. Traditionally houses here have boilers on gas or fuel oil.
For new homes you have to have a calculated level of energy efficiency (insulation, green energy of some sort, good ventilation,...). This made houses more wind-tight, so no wind/air is naturally entering the house. That's why we are obligated to have fresh air supply: special gaps in the window with air extractors, or for more fancy homes a small AHU with heat recovery, just for the ventilation (not for heating). This is why in Belgium we still have air ducts, but to save space, they became smaller and smaller, using some kind of plastics as material, in stead of steel ducts.
About CO2-monitoring: CO2 is more easy to monitor than oxygen (O2). "Consumated" oxygen mostly converts to CO2 and that's why we measure CO2. So don't just use an air purifier in stead of proper ventilation. The air purifier can reduce CO2, but wont add oxygen!
At my place where I live, the home automation monitors the CO2 in the living and bedrooms, and monitors the humidity in the bathroom. If they are to high, the ventilation ramps up from low to mid, or from mid to high. I still need to find a way to log the values of CO2- and humidity-sensors. They use a 0-10V signal.
$200 for just the GUI module... Ouch.
It's actually really hard to find such a nice display for the money. Wish these things didn't cost as much as they do.
At that point one may just repurpose old tablet or touchscreen laptop.
Yep, your pretty much on point with that assessment, at least here in eastern Washington while I will occasionally still install a traditional air duct style system, since moving to new construction its been 90% mini splits.
I just finished a project using a reTerminal, a USB to DMX cable, and a cheap DMX light to have a simple, scalable light system controlled via a Node Red flow. I think that's my favorite use case for the reTerminal right now - a Pi that can run Node Red and be a kiosk for the dashboard all in one easily mounted package.
I bought one a few months ago but have yet to open it. I have been upgrading my hvac system slowly. The biggest energy savings by far were putting a vfd on the blower motor to control to duct static pressure. Vfd on the compressor to control to discharge air temp(52F) with evap coil temp feeding in (prevent evap coil freezing over with min speed set to 40hz), evaporative assist on condenser to lighten the load on the compressor and dampers on every room to control to room temp and occupancy (with minimum airflow). I have an outside air damper that controls to a weighted average of CO2. Its funny because most of this is standard for commercial in cali under title 21. The whole hvac system used to consume about 1.1-1.3 kw/tR but this summer averaged about 0.4-0.5 kw/tR. It was costing ~$1.00 per hour @ $0.12 per kw but this year it was about ~$0.30 per hour @ $0.12. (6 ton system in TX) I use a rainforest device to connect to my smart meter and CTs to monitor power usage to key circuits. tonnage/load measurements were derived from airflow and temperature delta before and after evap coil. A flir is great for finding leaks in a positive airflow system. I used to do chiller plant optimizations for data centers in cali. If they listened to our recommendations we could easily get 0.23 to 0.32 kw/tR. (At the plant, hard to factor in crac, pdus, etc power usage)
Maybe it varies in different parts of the country, but up here in New England we still do a ton of traditional furnaces with standard duct work. Where we use mini-splits is when there is no existing duct work, usually houses with hydronic heat. It’s not that you can’t run duct work in those homes, it’s that you have to take over various closets and find places to run the duct. It’s a huge pain and very expensive.
Installers overall, everywhere in the country like to be in and out as fast as they can, and do as little as they can, as long as the job works (mostly) correctly and they don’t get called back.
I once lived in student residences that only had wired internet and that blocked wifi routers. So, I turned my RaspberryPi into a PiFi and basically just used it to forward a wifi signal to my other devices via a dongle. Worked great.
Nice, but none of that was about x86. The seeed reterminal is raspberry pi cm4. Maybe change the title?
the video just hit the free feeds. I am bit confused what's wrong with the title?
The title just asked what would YOU do with SBC.
Indeed. I came into the video expecting him to at least mention an x86 alternative to the Pi.
I'd use a wall mount interface like that to organize my garage. Lots of boxes of parts and I've considered numbering them and listing what's inside so I can look up "hdmi cable" and have it tell me what box to go to. Eventually I'll do it with a Google doc. But I haven't yet amd this would be way cooler
add a 2d barcode to the box, add a DB so you can track numbers of items too, it's no good looking in the right box if it's empty
This is a potential device that might fit where we created messaging, interactivity over PSTN old telecom over FSK channels. In rural long runs or out of range cell service the usefulness of the old wireline network is helpful for resilience outside internet. It’s like using the signaling you did on the alarm for best use of old tech. Very interesting. Integration into cellular network and other infrastructure takes away “cloud dependence.” This device could be the interface in rural out of cell range.
I would like to use one of these to monitor our rabbits and our outdoor stowed water. Monitor the temperature at a few points, turn on a heat lamp or submersible water heater, control a small fan.
IOT home weather station. Water flow/ pressure monitoring for hot and cold. Live electrical usage graph. IOT pool control/monitoring.
I love this thing, I want to get one so I can control my Humidity, Lights, and CO2 Levels for my Vertical Gardens around the house.
Paired with a few small ESP Wireless modules with some sensors on it.. I've got USB/WiFi Enabled Plants.
- Strawberries in the Winter?
- Fresh Tomatoes all year long?
- No Reliance on California's obnoxious water use for irrigation
I am converting an old ambulance into an offgrid home for travel. Using three reTerminals as part of the build. So far these have held up to the extreme conditions. I have very specific needs for interfaces and do not want to waste time and energy with a consumer mobile OS. It nice to boot into a control panel and see data in real time without any other BS in the way. grateful to have received mine before this video dropped. reTerminal's are no longer under the radar. ;)
In most modern homes they arnt tight enough to need fresh air from the outside. Which is why it’s like pulling teeth to get a tech to do it bc the second you say it and you don’t mention that your house is well above spec they will see it as a major waste of time. And what they arnt telling you about the load calculations is they are good to about around 90 degrees then your going to be lucky to stay 20 degrees under that temp . So adding extra heat when you might not need it = extra service calls in the summer when demand is utterly ridiculous for every contractor in the area. And be very mindful of the ceiling mounted models . Hopefully they come with a standard kill switch if the drain gets clogged. If not it turns your ceiling into mush. They are really great until that happens then they are a really bad idea . Just have to make sure someone comes out and does a proper pm on it.
I love this stuff. But I feel exhausted all the time and do not want to think anymore when I am done with work. I just want to sleep and work out.
If it was a few years back, I would have liked a x86 SBC for a DIY laptop. Now I think Framework's motherboard has covered that case.
One product I think should happen is an LED fixture with connections to LED strip lights. Most rooms have a central lighting source in the ceiling, with power already going there, but LED strips let you spread out. With the central fixture having all the IoT smarts and voltage rectifier/regulation, you could connect up all the strips and control them together.
"Nothing but a breeding ground for Tranks Lobos and Zipheads . . ."
"Don't you know it's dangerous to come home without lights on?"
"Lights on?"
I like your approach to failsafe systems like using thermostats which continue to work even when the cloud connectivity is down. Also, I hope the new IOT boiler control system will be backwards compatible with the legacy boiler snake technology.
Re: Nest. I have a nest: the problem is controlling it from your phone etc. if the internet breaks and it is a PITA to put on Home Assistant. You have to become a google developer etc. Apparently they are improving it but don’t trust them. It would however work like a normal thermostat with No wifi in that you can change temperature by hand etc. If the base u it and the head unit can’t talk you can even turn on the heating and water for half an hour by pressing the button on the base. It’s not that bad. It’s the lack of local control that I find annoying. If the area’s wifi goes down but your house stays up it should still be controllable over wifi, but it isn’t. Just add a local API…
I turned a Pi 3 with a 7.9" ultrawide touchscreen into my dashboard. It communicates with the ECU via a CAN gpio module. It's pretty sweet.
A heat exchanger is a great idea, really; but the modification type of installing is a hassle.
I have 0 use for home automation. I have successfully figured out an interleaved activity schedule in the morning to compress an hour of getting ready into twenty-ish minutes.
I want the smartes thing in my home to be me.
I have been looking at getting a radon monitoring system. I have an old house with limited ventilation in the winter. They are well over $200 for a decent Iot version
Ah, so that's where all the CM4's went.
Careful about the CO2 sensors: most cheap ones are not actual CO2 sensors but TVOC sensors that estimate the CO2 from TVOCs. The actual CO2 sensors can be had for ~40 bucks, and they are *much* better.
I'd use a real sense depth camera and ROS to build a hand held 3d scanner on a very low budget. options for both streaming to a more powerful computer and using the hand held scanner alone.
immediately pipe a bunch of data to it from our server racks at work, and have a little grafana dashboard on the wall. Would be super nice to just pop in and take a look at thermals/drive stats/nic stats/netgraph stats/etc. plus it makes the rack look as cool as stock photos make them look
at home it's instantly becoming a super dope monitor/controller for my plant irrigation/lighting/hvac/thermals/etc
ah yes, the IoT "convenience" issue.. a must have for OLD folks.. helps to keep us from looking "DUMB" as we leave things ON when we go out to dinner.. Emma to Bob: Forget anything honey?? oh look, the TV is ON Bob.. do ya feel less smart now?
I would love to see POE lighting and solar/battery internet of things
I would like you to do a review on Veeam immutable backup solution compared with other backup immutable backup solution
Very nice. IoT fridge project when?
Use multi mmwave sensors to create indoor radar. Track movement via screen
Originally boinc, messing with Linux, and was going to do emulation but prefer on other devices, and now as a pi hole because you reminded me
I live in Ohio. Most HVAC installers are still using ducts. I asked a sales guy why and thought his response was interesting. Do ducts ever go bad or need replacing? Not really. Those cassettes or wall mounted mini splits are expensive to replace when one goes bad. For it people, It's like having one large copier vs 5-6 printers in your house.
i am about to get some raspberry picos setup for reading door status and temp/humidity all over the house, already have one doing a thermostat (will fail into dumb mode unless the SOC dies, and i have jumpers for that situation)
For my car, I would love to do navigation with openstreetmap and streaming from my Jellyfin server for some music.
I am still waiting on my Home Assistant Yellow to get here so I can resetup Home Assistant. As far as what I would do with a reTerminal, I am not sure. There is so much to do.
I was just gonna diy one but a thermostat kit would be nice
i don't REALLY need it but it could be cool to have fine control over the EV charger i got. i know the charger is in the car poteto potato. :)
there is a transformer input which basically tells the charger how much current the whole home is drawing, then the charger knows the maximum that can be drawn and does the math by itself.
unfortunately it's not possible to install the transformer without absurdly high costs (digging the main cables out of the ground and having to fix the common green area expensive... not gonna happen) so i'm using the car current limiter to manage the carge as "regular charge" or "MAXIMUM SPEED" using a custom made app either via direct connection or my vpn tunnel.
using a resistor network and some small transistors i could emulate the signal coming off the transformer and simply decide say "i want to draw 14A" and the charger would follow blindly.
i know there are chargers that allow remote control but most require weird apps and accounts aaaaand the usual invasive stuff, also unattended multi-kilowatt stuff near an EV made out of chinesium eehhhhhh i'll pass.
as an added feature provide wifi to the EV, with ethernet derived off a powerline adapter - YES POWERLINE I KNOW but by code i can't run ethernet in pipes along with mains and there ain't free pipes in the walls soooooo yeah.
1:30 that's why when I go do bed I do so in a garage with my a car running.
My white whale is, using some combo of home assistant, OpenCV, and tail scale? To have a pan tilt zoom camera that zooms in on faces of people that walk onto property as well as zooms on to cars and license plates, logs the information, and alerts me via a panel like the one in this video, or my phone if I’m out. The reason it’s important is because robberies are almost never just some random event. Most criminals stake the place out to try to rob you when you’re least likely to be home. I feel like a ML model could alert me when a car / person that I haven’t cleared keeps showing up in front of the house
In a less sinister but similar technical challenge. I have a home garden and fortunately don’t have too many pests. There are neighborhood stray cats that hang out and keep the rodents at bay, and possums which I guess are good creatures, but we have a ton of SKUNKS and they dig up gardens bad. Would be nice for a ML model to detect if an image is a skunk vs possum vs cat vs dog and activate the sprinklers or hypersonic alarm if a skunk is on premises and none of the other animals are around
I have looked at these displays before
i would love one as a general HMI for all sorts of projects
i realized about a year ago that i was creating a whole front panel interface for all kinds of personal projects when in reality i just need an ESP8266/32 and a raspberry pi running some sort of python QT UI and carry it around project to project, test equipment to test equipment
I'm going to email you a PDF with my "old" project for a fully integrated domotics system (home automation) which I have never completed because of once I completed the project description I realised oh crap I won't be able to complete it alone.
That said, there still isn't anything on the market to do a fully integrated system as I describe which I believe fits your own preferences due to not relying on any third party cloud storage and/or similar things and instead uses your own local NAS etc. If you need/want or would grant me the pleasure or working on getting that up and running I'm even ready to get a website up and screaming the whole solution and it's guides and products (to sell or point where to get).
Please let me know if you get the email :)
1:51 Oof the price went up to $133.02 on Amazon. I ended up buying it from a third party seller on Walmart for $105.95
Smart house of no internet.
Dang no I wanna iot-ify the window unit connected to the central air unit
Man, this is like so cool for my future home.
Been planning out a carputer for quite some time,
I'm interested in automated window blinds. I'd really feel like I'm living in the future if I could open the blinds in my house with the push of a button.
7:01 "This does not cost a hundred dollars", pans to a price tag of $97.90 - so, yeah, technically correct, but.. 🙂
Any chance of a video detailing a way to turn on and off larger equipment like space heaters?
Wendell, dude... Nest thermostats DO work when the internet is down. You simply walk up to the thing and adjust the temperature, just like you would with any other thermostat. The app itself may not work, I'm not 100% sure about that part. But it's not at all like the thermostat is useless if your wifi or internet are down as you seem to have suggested here. Now I completely here you as far as local access working (the app should not depend on cloud, and again I'll test that later,) but it's also not as bad as the sensationalists and click-baiters want you to think.

it used to be my whole server(with storage on a synology 2bay nas) hehe, it ran all my **arr-services. the lowpowerness of it was great but running it headless was more of a hassle than I wanted so when i upgraded my desktop the old one replaced the pi. it worked fine streaming video with emby but it basicly needed directplay. some lower-bitrate video was able to transcode tho which i didn't expect. it was nice to thinker with but the system now is faster and mostly more accesable bcs i just use barrier to control both pc's.
Would love to see how to retrofit IoT controls into a minisplit that doesnt come with such witchcraft. I have a Mitsubishi that works great but requires a dumb remote.
In regards to monitors have you reviewed any of the SAMSUNG 4K monitors G7/G8?? I'd love ve to see how they stack up to the Gigabyte M32U.
I want an IOT I can set and forget. Easy to manage and change settings. Then I'm in. So far you have to know how to code to make any use of these IOT schemes. Why not use an old dual core windows laptop? Why a Rass Pi? This would give access to the programing to more people. Even if it was an old XP system you could do more. It's not a case of short of space or needing portable system. Just need people to build the operating system for IOT. Much cheaper than buying into the Pi system. Just a basic Pi in Canada is over 100 bucks. You can get a laptop for that.
"Why not use an old dual core windows laptop? Why a Rass Pi?" you can. Nothing stopping you. But no, you could absolutely not "do more" with that. And why not? Efficiency. You'd be throwing money out the window in the form of heat and energy. If you have a laptop laying around that you'd rather put to work than sell, that approach might make sense. "Much cheaper than buying into the Pi system" no. The Pi's MSRP was about $30 before inflation and chip shortages. If you can get something cheaper, that's great, but you're arguing against a skewed market, and the case has always been that if you can get cheap used electronics, you might personally find some value in that. Some of us have Raspberry Pi's laying around in abundance from when they were $30 and readily available, or would rather have a small form factor and efficient system. Your examples and argument are pretty self-focused. There's absolutely nothing stopping you from running the same software or same code on an old laptop as well. If you need help doing so, there are tons of helpful communities out there that would help. If you run into anything in particular, I'd be happy to assist too.
holy crap i need to slap one of these on my 3d printer immediately
my Raspberry pi is my network’s dns controller, ad blocker, parental control filter, and unifi gear controller. Eventually I’ll add nas functionality. I’ve been wondering what else I can do with the pi
I have to tackle this topic (filtered fresh air, positive pressure, activated carbon filters etc.) in several places soon, too.
Is there a trustworthy source to introduce you to the basics, for example what materials should be used for which specific piping with an explanation why (i. e. insulate copper piping to avoid condensation/mold etc.)?
Would like to learn a bit of detail here to not be solely dependent on “professional opinions”, have had very bad experiences in the past here.
start with stumpy nubs?
Thanks, the direction is right but it could be a bit more serious/more dense with information - also seems to focus more on woodworking instead of air conditioning.
@@abavariannormiepleb9470 and people building their own filtration systems... move their particulate filter boxes to hepa.
I've been trying to figure out a way to do nice, not janky sensors for my wife's plant obsession. I did some esp32 stuff but bare esp32 boards are a non-starter for her.
Those are HA wall panels!!!!!!
I wonder if that thing will run Kllipper. Need a Pi for my printer.
What about doing your ductwork yourself? It is not that complicated. In your private home you have all the time in the world, and you do it for yourself, so not standards lowering/no cost cutting here.
I'm sure most of you are aware Rasp Pi Prices are ridiculous at present.......
Smart Home Door Bell Screen... (etc)
cant believe this is the first i have seen on your IOT becuase i have seen a crap load of your server stuff but everything i search IOT you have never popped up
The current state of HVAC in Europe (and probably a lot of other countries with mild climate and old houses): 404
I pray for the day x86-based SBC computers will cost around $30 and will let you hack every corner of your house and share content with the rest of the world. Every socket, every appliance should be a computer with settings adapted to your needs.
please do a multi node iot server
like raspberry pi and lattepanda multinode box for devops
i need a reference please
hope all units are usb c
x86 pi? RETROCOMPUTING!!!
not really into iot stuff, dont care if i manage it or not,it's more crap to hope wont get used against you in 2 years.
that being said, why was x86 in the title? i thought you were gonna talk about a x86 sbc or something. nothing wrong with the video itself, just dont get the title.
This seems like it would make a good Home assistant/thermostat interface. Ive been looking for a device for just this purpose BUT I want something I can power from the 24v from my HVAC system which is what has stopped me so far. Every solution ive seen requires cutting into the wall and installing an outlet to power some type of tablet device and I really want to avoid that.
Just get a 24vac to 5vdc converter.
Interesting, very interesting...
Why are they named after a German hip hop band?
meh, I already use Alexa. Home assistant will be nice when I build a house
Your just flexing that you got a pi in these trying times.
Nothing. There’s mountains of off-lease x86 whole mini computers for less money than it costs to ship them to me. Expensive new SBCs are superfluous in this economy. Not quite as good as the post-dot-bomb hardware values, but it’ll accelerate.
esp32 such bloat, all you need is esp8266
arm is superior
x86
Anything I want
Neat
Hydrofarm 🙂
200USD for that junk, no thanks.
Hey Wendell, had you lost some weight? It looks like it 💪
Price 👎💸🤑
I honestly think this is all really cool.
But you should honestly measure RF levels in your home and check how much exposure you're going through on a daily basis lol
Coz I'm hearing a worryingly big amount of "wireless connectivity" talk in these videos...
Well, than you shouldn't use a microwave, as it emmits a magnitude more than your average wifi-antenna. But having said that, it's non-ionising radiation. I would only be worried about ionising radiation. So it's perfectly safe.
@@ChristopherMahn you don’t get exposed to the RF from a microwave because the metal grill and body act as a faraday cage. OSHA has standards for RF exposure. It is relatively safe, the biggest concern being localized heating
Ah, always that Raspberry PI stuff, i'm getting bored of it... wait, what?
Edit: Only good IoT is no IoT. Aren't we stupid enough already? Do we need this extra dumbing down so we don't even turn knobs anymore? Nobody is that busy that they can't fistbump a switch on a wall when necessary or push a button on a remote, and if they are so important and busy, they have slaves on minimum wage who can get far more easily reprogrammed (fired) than this thingamajig.
My AC starts only after a well angled dropkick on the external unit and as long as it does, I have two benefits - I practice my dropkicks Kirk-style and that's about the only exercise my fat body ever gets. So keep this witchcraft away from me!
Sir, this is a Wendy's.
