- I had a call from @GaryDoesSolar asking if I can help him with a little battery problem he has. Whenever his Intelligent Octopus Go tariff from @OctopusEnergy gives him an additional off-peak slot to charge his car, it takes power from his batteries. He'd like to somehow charge his batteries using these ad-hoc off-peak slots and that is definitely something that Home Assistant can help him with - but he'll need Home Assistant up and running first! In this first part I'll go over the shopping list of components I sent to him and explain why I chose each item.

Saying hours or days....well I have found weeks or months of time lost to Home Assistant. I had this same problem when I swapped to Intelligent Octopus and the extra slots confused my Tesla Powerwall and emptied it into the car. Adding a couple of integrations for Tesla and myEnergi, I was able to create an automation that moved my battery between backup and normal operation depending if the zappi was charging outside the usual 11.30pm to 05.30am.
Putting the Tesla into backup mode meant it also recharged from the grid using cheap energy.
Your list and details of how to setup was certainly what I would agree with.
Or years :( It's when you wake up one morning and an automation hasn't worked you then can't think about anything else until you've figured out why it didn't work... that's where the time goes!
@@SpeakToTheGeekTech Definately!!! Always something to tweak or update.
@@SpeakToTheGeekTech I have found Ghat GPT is great for trouble shooting automations, then ask the Microsoft one (can’t think of the name) to check it and explain the logic. It is also great for writing the initial YAML code. It can type hundreds of lines in seconds which would take me hours to type and debug. If you are logged in it also remembers the code so you can say “That last automation doesn’t quite work, can you check it and find your mistake” It then very diligently checks it’s work. All great fun in itself apart from being a fantastic time saver.
Glad to see you’re tackling this issue. I have been looking at it and have solved it in exactly the same way with Home Assistant. In my case I have Tesla Powerwalls but have managed to stop my battery discharging into my car when its on an Intelligent Octopus tariff where the schedule changes during the night. Looking forward to your version of the solution Gary.
Do you mind me asking how you controlled the Powerwall using Home Assistant? I thought their API only allowed read-only access apart from to take the home off-grid?
You can control a few aspects of the Tesla API from Home Assistant. As you said Home Assistant is fiddly to learn and setup but once its working the automations are relatively easy to use and can offer many complex scenarios.
I control the Backup Reserve %. If you set this to the current battery % value this effectively stops the battery discharging. If you want to also charge the battery while the cars charging then you just up this to 100% and the Powerwall starts charging. This can be done relatively easily with a Home Assistant automation.
I do not have any way to know the Octopus schedule at present ( presumably they will offer an API in future) but I do have a CT clamp on my car charging cable so I know when my car is charging or not. The CT clamp can be read by Home Assistant so this can trigger automations.
I have some automation which detect when the car is charging. So based on what time it starts/stops I can presume it’s an Octopus schedule as I typically only charge the car overnight. I assume any stop/start charge before 10am is from Intelligent Octopus so I control the battery based on that. This is relatively simple but works very well. So if Octopus stop and re-start the charge a few times then the battery synchronises with this and importantly does not discharge into the car.
There is a slight sting in the tail though.
The Tesla API has recently just changed its authentication mechanism and so it’s quite difficult to get Home Assistant integrated with the Tesla Fleet API. Its really for those who are very technically minded and understand API and development commands like curl and understand hosting private / public keys. I guess Tesla wants their API to be as safe as possible so this is why you have to jump through a lot of hoops to be able to use it.
Hopefully Tesla will make this integration easier in future or perhaps Tesla will improve their hardware. The Powerwall could also do with a special CT clamp integrated to the Powerwall software so the Tesla system can detect when a car is charging. Perhaps they will offer this in future but for now its a fairly involved DIY project to work this out. Tesla Fleet API integration notes are here. I had to follow all of this. www.home-assistant.io/integrations/tesla_fleet/
Hopefully Gary will find some easy way to do this.
Didnt think you could access the Tesla Powerwall 3 from HA. Believe you can control it using automations in the netzero app. @SpeakToTheGeekTech
Thanks Oli - looking forward to seeing just how powerful Home Assistant is! 😃
Welcome to the dark side :) Or the light side, it depends how you set the automation up!
To be fair you do have a lot more free time now to lose in home assistant 😂
For those with a Powerwall, the Net Zero app can achieve this simply and a lot more. I have mine set so that if the home usage exceeds 7 kw, the backup reserve is set to 100%. This will trigger charging at the cheap rate. When it falls below 6.5 kw, reset it to your normal value. The app is also a useful addition to the Tesla app. One useful feature allows you to add your solar arrays. It then gives you the predicted generation for your location and the weather forecast. This plots on the solar generation graph.
Thanks, I might be making a Powerwall version of my automation at some point too!
@SpeakToTheGeekTech That would be useful as I've only had the Powerwall for 2 months.
Sounds like Gary needs what I have written. I use Solax batteries and intelligent octopus go as well, and set my system to do the same, charge the batteries in the extra off peak periods as well as at night, but I went a lot further. I predict the hour by hour home consumption of energy, as well as the daily solar energy production built on a model I’ve accumulated over 6 years of data so I know the average energy I will get every hour of the day for every week if the year. I can then predict my energy needs for the day but crucially I do not overcharge the batteries to a point that excess solar will get exported. I still get FIT payments, so I want to keep every Watt produced for myself. So then when a cheap period kicks in, I set the battery either to charge, or to hold its existing charge depending on my need. I never use the battery to charge the car, I always ensure that it uses the grid only. It’s been working flawlessly, but I keep tweaking it every year as I find better ways to predict the solar production.
Very nice! That’s possibly a bit more complex than Gary requires especially as he will want to export because he gets more for that than his off peak costs, but I understand your needs around FIT! Have you seen Predbat? That software might achieve similar results to your automation.
@ I’ll check it out, thanks. It’s the solar forecasting that’s the hardest to get accurate, for home consumption I have a very accurate hour by hour, day by day predictive model. Was going to look at solar irradiance modelling this year as well as the cloud cover modelling I already do. Whatever we do….we can always find ways to make it more complicated!
Very sound hardware advice there, although I decided to run my Home Assistant on a Synology Virtual Machine. It works fine, as I am sure a Raspberry Pi would too.
I'm new to HA and, with a specialist programming background, which it's fair to say that HA is a very different animal than what I am used to using. The biggest issue for a relatively old duffer like me is getting to grips with the terminology - it can be very confusing initially.
In my experience, HA is pretty good at doing the simple stuff and the concepts are fine and it suits simple triggers and affects from them with ease. Where it gets more tricky is once you leave the basics of triggers and HA flow chart programming and have to get into YAML coding to do specific things, then it gets more tricky and the debugging tools aren't great.
In my case I am trying to control the charging of Alpha ESS AC coupled batteries and trying to make use of the best times on Agile. There are devices and services which help but it still requires a fair bit manual coding to do what I want. I've also been programming the immersion heater to come on when the cost of electricity is less than the cost of oil - this time using a Sonoff switch. As Agile is dynamic in pricing and some of the services are a little unforgiving, it's been a challenge to get things working how I want them.
In my case, spending a few hours is an understatement - quite a few elapsed days would be closer to the amount of time spent so far! However, having not done any real programming for several years now it's been kind of fun .... and equally frustrating too at times! ..... but I am getting there and I am pleased that I have stuck with it .... well, engineers seldom give up, do they?
As you're on Agile, have you investigated Predbat? It'll work out the cheapest slots for you and can automate all sorts around that including optimising your battery charging (not certain if it supports yours, but it's worth looking in to)
@SpeakToTheGeekTech I've looked at the Bottle cap Dave , but not the one you have mentioned. They seem similar. Many people are accessing Alpha batteries via the modbus. For now I am sticking with a write via cloud services. I have it doing what I want, finally, albeit, in a slightly clunky way.
I've just checked - Predbat doesn't support our battery , unfortunately.
Nice clear talk through. Looking forward to Gary's update.
Me too! I'm working on a tutorial video for the automation I've put together, but I've no idea what Gary is going to think of it all so I'm as invested in this story as I hope the audience is :)
Great video and I love the cameo! I can see I'm going to be wasting days of my life setting this up once I get a battery.
If you’re allowed to get a battery, you can’t even see it inside the house so what’s the point? :)
@@SpeakToTheGeekTech It's pointless, I know. I don't know why we even bother having a roof either to be honest. We should live in a transparent cube.
Ooh, exciting. I'm embarking on my first Home Assistant build as well, mostly to integrate solar, battery, heat pump and power monitors into my smart home. I'm already subscribed to both of your channels! 🤓
Good luck and thanks!
I've just bought an Ohme Home Pro and once installed I'll be moving from Octopus Go to Intelligent Octopus Go. I'm preempting this battery discharge and my first solution is to change my Consumer unit cupboard cabling layout from one Henley block to two Henley blocks so the EV live is seperated from the house loads. The EV CT clamp goes on the live meter out so it sees all loads and the battery/solar CT clamp goes on the new Henley EV block Live out, thus the EV live draw is not seen by the battery system.
I bought a cheap Dell Wise small PC and I have HA setup on that but so far it's not being utilised.
Yes, physically making sure your wiring is set up as you describe is one way around the problem. Not possible for many people though, and I think Gary will be discussing that in his video next week as one of the possible solutions. You could use my automation with the Ohme but you would need to install a power monitor on the Ohme's feed and create a binary sensor that is on when power is flowing, off when no power is flowing, effectively giving you a sensor that says "car is charging". You can use that as the signal to my automation (coming up next week, or live now for members/patreons) to tell the battery to start./ stop charging.
@@SpeakToTheGeekTech There is a Home Assistant integration with Ohme chargers which means you don't need the power monitor.
Home storage batteries discharging when you charge your car on IO Go must be the most common problem out there. Fixing it with a Home Assistant automation is not for the faint hearted it took me months to work out how to do it on my FoxESS/Zappi system and I worked as a software engineer for 40 years. My advice for anyone choosing a home storage system or car charger is to get a car charger that is compatible with the battery storage system so for a Zappi that would be a Libbi. Let's hope that at battery suppliers start thinking about this problem as it wouldn't be that difficult to provide functionality such that this problem could be fixed by the battery system. Also installers need to know that they can configure the wiring such that the battery is never discharged into the car as in most cases this is not desirable and can be fixed by simply moving the supply current sensor if the house wiring is arranged correctly.
Honestly it took me about an hour to put together the automation I’m going to demo in next week’s video. Takes about 5 minutes for people to install via a blueprint, but you do need to install a few prerequisite components first which will take the bulk of the time.
@@SpeakToTheGeekTech Look forward to see how you did it, For me It was easy enough to monitor the Octopus current electricity cost but I had to call a FoxESS cloud service to control my home battery system and that's what took the time in Home Assistant
I thought about rasberry pi but in the end bought a GMKTec g5 with a N97 processor, 12gb Ram and a 512 gb ssd with W11 Pro, these are often on offer and cheaper if you dont mind the wait when it ships from China. Loaded virtual VM ware and HA on to that. Works really well.
Yup a great option, but not really suitable for a total beginner due to the extra complication of running your own virtualisation host, which is why I suggested the Pi. If you're comfortable with virtualisation then nothing wrong with your approach, although I personally would have avoided VMware due to their recent licensing controversy. Something like Proxmox is considered is considered to be a friendlier product from a hobbyist perspective now and HA runs nicely on that as a virtual machine (or even a Docker container if you wanted to go down that route)
Have you got a link to that?
@@SpeakToTheGeekTech Proxmox looks interesting will have to load it and see how it goes . The hardest part of VMWare was working out how to download it, after that I followed an out of date video and for HA the instructions on the official site. I struggle more with HA.
@themorfill Proxmox comes up when googled. I opted for a nuc due to the tiny size , lots of alternatives, the GMKTec is dearest on amazon, cheapest on ali express but not too bad from manufacturer but the price does vary. I couldn't get it to work reliably on WiFi, despite fixing ips there always seemed to be confusion between the nuc and HA inside VMWare but no issues over Etherley.
It's great that you are showing how to do this. I have a similar setup and this video is exactly what I was looking for!
My only comment was I wonder if adding the extra kit to the Pi will put some people off as the price increases. I have it happily running off a raspberry pi 4 with an old SD card.
If it works for you then that's brilliant. My concern with using an SD card is that they are known to fail due to the heavy writes performed by Home Assistant although you can now get some top-end expensive SD cards that are supposed to be just as resilient as an SSD. My concern was that people would be put off if the Pi died due to the SD card failing after a few months (as has happened to me many times!).
Ditto here also : HA beginner here, I've dug out an old (but unused) PI 4 desktop kit (which came with everything incl SD Card), and in a day, I've got it taking to my Ohme API, so can hopefully adapt to my setup in this upcoming series. 👍
Update: 4 hrs later this evening, I've now got the octopus API, Victron Cerbo API & Ohme API all reporting data (sadly the Daikin Altherma API given Oli? - are not quite working yet) : but looking forward to this series in anycase.
Looking forward to seeing where this goes - I've tried to get my head around Home Assistant running under UTM on my Mac but obviously not spent the necessary 'days' learning it! (As a 20-something years ago ex-Unix and Novell sysadmin I thought it would be simple - glad I'm out of that world these days!)
The GivEnergy battery discharging is relatively simple to get round by adding the time using their Inverter Settings 'Timed Charge' slots in the app when IOG tells you that you will be getting some outside the scheduled night rate - and remembering to delete them the next day! But it's a bit of a faff.
With Home Assistant, you should start with "I have a problem that needs solving" rather than "I'd like to see what I can do with Home Assistant". If you go with the latter then you tend to end up with a server sitting there doing nothing because you're not sure what its purpose is. Hopefully this automation (coming next week unless you are a channel member or Patreon, in which case it's up right now) can be the catalyst to get you started :)
@SpeakToTheGeekTech for sure - and getting the domestic battery to charge at these odd times is exactly what I'd like Home Assistant to do!
I'll keep an eye out for how Gary gets on with it.
Thanks for this video, I'm looking forward to your & Dave's follow-ups.
I'm in the process of transitioning from a Fibaro HC3 to Home Assistant, which seems better & more flexible.
I started my HA journey by installing HA Container on my NAS but quickly discovered that this version has all sorts of restrictions, so have switched to a mini PC that came supplied with HA OS pre-installed.
I was able to backup my 'NAS' HA and transfer it to my mini PC, so hope that this will also be the case if I decide in the future that Raspberry Pi is a better option. (Or if my mini PC ever fails.)
I opted against a Raspberry Pi because I'd read that they only work with SD cards and wanted to use an SSD, for the reasons you mentioned.
Half-arsed research let met down again. 😖 (Although the mini-PC was reasonably priced and the pre-installed HA OS helped me on my way.)
As long as it works for you, that's what matters. My advice is only a suggestion based on the logic I described but there's no wrong answer I guess if something suits you better.
Why not use a thin client?
Cheap to buy, pretty cheap to run too.
I bought an HP T610 on ebay for under £15, only thing I added was a 160 GB hard drive (that I already had) and hey presto, done.
Even if you go with an Intell NUC it'll still be pretty cheap to buy and run.
Not great for a beginner though - talking someone through installing Home Assistant on a computer that doesn’t have a standard image for Home Assistant is a lot trickier. The Pi was chosen for its standardised image and wide support.
Just wondering why a PI over a ready to go home assistant green?
Home Assistant Green is lower spec than a Pi 5 and also custom hardware. As mentioned in the video, a Pi is very widely used and supported so you will almost certainly see fewer bugs overall and it'll be easy to get a replacement Pi from a variety of suppliers if something went wrong. The Green also only has 32GB eMMC storage built-in so tricky to expand if needed. By using a separate SSD you get faster storage, longer lasting storage (most likely) and it's easy to swap over or re-image if needed. Absolutely nothing wrong with a Green, but I personally think a Pi is a better choice. They're also made very locally to where I live (Bridgend), so supporting local businesses!
@ sounds good, I went with a green just for convenience, that said I have 3 Pis as well
Yeah, it is a convenient all-in-one package. But I like my Pi :) And just so as you are aware, you are on my Home Assistant Nemesis dashboard... keeping an eye on your subscriber count going up, can't have it overtaking me! I've got to put in some serious work to stay ahead :)
@ lol i am honoured to be a Nemesis, given I’m a mere beginner with HA, however do have a video or two planned for February on the topic 😂
British green-tech RUclipsrs can earn a place on the dashboard :) There's always one Prime Nemesis though which is my target to catch and overtake, with everyone else on there with a 'must keen an eye on' status. Shan from Everything Home was my first Prime Nemesis, then I moved on to Tim & Kat's Green Walk. I've currently given myself a stretch target of EV Nick but his Cosy 6 adventure gave him a boost. He knows I'm coming for him though, I'm biding my time :)
Good stuff . I’ve been doing that for a long time with HA. Following to see if I’ve done it how you will albeit with a different inverter.
Next video is hopefully out next week :)
I am also surprised that a HA Yellow or Green wasn't chosen. Having run HA yellow for some time on a fairly busy system with Graphana and Influxdb for stats, when Predbat was added everything became "a bit laggy". I have just upgraded to a CM5 and we are back to snappy responses, so I was surprised that the CPU (and probbably I/O) maxed out so easily on the CM4
A yellow is no easier than my full Pi suggestion really. A green is beginner friendly but I really think a Pi Is best for beginners in the long term for the reasons discussed in the video
I started off using raspberry pi's, but soon found that with some of the heavier add-ons (predbat) that it was beginning to struggle. In the end I bought a thin client machine (Lenovo ThinkCentre M720q 256GB SSD 8GB ram) for £90 and run multiple vms on it with proxmox. It's tons faster (x10+) and as it's replaced two pi's so it's doesn't really use much more power either.
Yup, whatever works best for you! I would say though that your setup is probably not best for beginners :) Promox is a learning curve in itself!
Strange choice of overly complex and expensive hardware. I’d advise anyone starting out to get Home Assistant Green.
I explained my choice: the Pi is a widely supported and used piece of hardware which is likely to be supported for a very long time. The Green on the other hand is custom hardware and whilst a good option for some, its smaller user base make it more likely to experience bugs (purely a numbers game) and more difficult to replace like for like in the future.
@@SpeakToTheGeekTech Home Assistant Green is certainly a better choice for beginners: as well supported as the Raspberry Pi, but less expensive. It consumes even less energy and is totally silent (passive cooling). What's more, it's already assembled and Home Assistant is pre-installed.
The only drawback is that there's nothing to do: for us geeks, it's less fun. Perhaps that's why your arguments in favor of the Raspberry Pi are weak:
Home Assistant Green is created and supported by the Home Assistant developers. They have committed to continuing to support their hardware.
Most Home Assistant bugs are common to all platforms.
There's no reason to make like for like replacement in the future. Simply choose any platform you prefer at that time and transfer your the Home Assistant backup.
I see you are setting up Home assistant on a Pi5 with a SSD. I already have Home assistant running Predbat with no problems. I have now obtained a Raspberry Pi M.2 HAT+ with a 256gb SSD. Will you be showing how to make the SSD bootable so I can migrate from the SD card to the SSD. Just need to get my head around making the SSD bootable and move data from SD to SSD.
No I don't plan to show that for your exact scenario, but the process is similar. You should do a full backup of your Home Assistant to a USB stick first. Then put your new SSD in a USB caddy, plug in to a computer, use the Raspberry Pi Imager software (from their website) to install Home Assistant to it, put the SSD in the HAT and power the Pi on (no SD card). It should just boot straight off it in to HA. Make sure it's up to date and then restore your backup and you'll be where you left off.
hmmm ... seems a load of additional work when you can get a ready made green or a future upgradable yellow, easier setup and end up being cheaper?
You can choose a Yellow or a Green or whatever hardware you like. My point with using a regular off the shelf Pi is ease of obtaining a replacement quickly if you need to. It’s not really any more complex than a Yellow/Green really
@@SpeakToTheGeekTechSays someone suffering with significant unconscious competence.
For the average non-technical solar/battery/EV user they’re worlds apart!
They’re gonna struggle enough with the software, without having to familiarise themselves with hardware concepts for no real benefit.
@@SpeakToTheGeekTech A green all in would have been a cleaner and cheaper solution.
Once again Oliver many thanks for a great informative video.
Although I already have a Synology NAS with Virtual Machine and Home Assistant it's scheduled to shut down and restart for a few hours overnight (nothing important going on midnight for 2hrs), however coming back to Gary I am currently on Octopus GO but when I can get on IOG will need HA to be on 24/7 so you got me thinking moving the HA onto an RPi 5.
I do have a spare 250Gb Jetdrive (originally used for the MAC and has it's own caddy) which I think would be ideal for the RPi5? I've already followed the HA install for Raspberry PI and that's gone okay but do you envisage any issues? 250Gb enough?
Appreciate all your help
250GB should be more than plenty, my SSD is 128GB and I’m not using more than about 20GB. If you have a Synology NAS then no harm in running it all on there though (if you leave it on!), or you can automatically back Home Assistant up to the NAS
I thought there was a built-in bootloader than could pull arbitrary images, which would eliminate the one-time SSD enclosure.
A bootloader was released in an update late last year but to my knowledge that only allows you to choose your boot media (SD, NVME, Network, etc) and not actually install an operating system - you also have to have a working Raspberry Pi OS image because you need to manually update the firmware to get it. There is an OS you can install on an SD card called Noobs which lets you pick an operating system much like you are suggesting, but again you either need to image your SD card yourself or buy one pre-imaged. There are many ways to achieve the build I am proposing, but I have attempted to find one that is guaranteed to work and is easily repeatable for others.
I too would love to do the same. However the support of Powerwalls within HA I have found to be frustratingly unreliable. I am looking forward to this collaboration!
I thought Powerwalls were pretty much read-only in terms of the control you have via HA but I've been corrected today that you can set the reserve %age too which effectively means you can stop/start the discharge. I'm assuming you know that given your comment, so are you saying it's hit and miss whether sending those commands actually reach your battery?
@@SpeakToTheGeekTechPowerwall control is not hit and miss, it’s perfectly reliable. It does however require the Tesla Custom Integration via HACS to give full control as the built-in Tesla integration is read only.
@@SpeakToTheGeekTech No, my issue is having a consistent connection to the Gateway/Batteries.
Eager to see how this works, I’ve tried setting up an automation for this exact purpose but it never seems to run!
Hopefully it'll be super-simple to set up for you, I've tried to make it as easy as possible
Just a thought but do you need an enclosure? I have an Argon case for a Pi4 and I just connected the case to the PC via the USB connectors and used it as an enclosure itself when I first installed. Not seen the Argon Pi5 case, I went down a different route for my Pi5, but I used the same technique to install software on my NVME.
For a Pi 4, you connect via USB and boot from that drive. You can do the same on a Pi 5 if you want, or you can use the NVMe interface directly (not USB) for faster disk access.
Are you publishing that ring tone?
Can people still buy ring tones? If so, yes! I don't wish to spoil the illusion though but that was added in post :)
Good video 😂 you need to check your message requests btw, Zuck has decided to interfere again!
Ahh ok I see the message now!
There really is no need to buy a NVME writer or enclosure.
You can write Home Assistant directly to the NVME while it is plugged into the Raspberry Pi.
Al you need to do is connect it to the internet switch on the RPI and write directly from the bootloader.
Assuming the person has a USB keyboard and a monitor that they could use, or I’d have to include those components in the shopping list. Most people just have a laptop now, so I’ve chosen a method that works for everyone
@@SpeakToTheGeekTech You've got a point there 😉
I have those, so didn't really think about that people might not have these.
I am looking for the same solution as Gary is!! I’ve lost count of the number of times my car has drained my house battery. I am very new to Home Assistant but have the HA Green. Will that work the same when you teach me to do the animation? 😂
Yes, the HA Green will work just fine with the automation and instructions next week. I just prefer the Raspberry Pi as a hardware solution over the HA Green for a number of reasons, but there's absolutely nothing wrong with using a HA Green at all.
I’m not the most tech savy person you’ll ever meet so the built option felt safer for me. If I can’t find a video that tells me how to solve my problem then I’m a bit lost.
