Our second Powerwall was installed today, and it wasn't long before tomho's excellent Windows version had recognised it and was showing the two charge levels. I've said it before, and I'll say it again, THANK YOU tomho. The lads who did the installation were totally unaware that there...

re the battery data: IT WORKS - THANK YOU. After half an hour's frustration trying to extract the details of the Gateway IP address out of a TPLINK router (that showed every ruddy parameter except that one (in the end I had to go in via the tether-app from a phone, and there the IP address...

Ah - why didn't I think of that! Thank you, all back up and running. Great job, very grateful.

I've got the current charge level back on the Windows version, but on my Android phone I've still got NaN showing. I'm in England, if that makes any difference. I hasten to add that I am eternally grateful for Powerwall Companion.

You raise an interesting point re peak demand for a consumer during the short cheap rate period. In spite of my continued loathing of the fact that Tesla ultimately - and often dumbly - control my system, we have just ordered a second Powerwall, taking advantage of the drop in price and...

@ xWren - It says Version 23.44.0 eb113390. Is that what you were asking? Interested to hear about the fall out between Tesla and Octopus. Is that why the Tesla Tariff disappeared?

@ tomho Manually outwitting it is roughly what I do, I don't sleep very well, so pretty much always have an opportunity to fiddle with the app during the night if it's not doing what I want. For example if it's not charged fully and I know I'll need a full charge for the next day (or I...

@ JohnRatsey - I set the storm contol to 10% less than the current battery level when we go to bed, with TBC. As I almost always wake up at a convenient moment during cheap rates I then change to self powered and set the storm control to say 70% if I don't want it to charge fully, or if...

I have no idea BGbreeder. Initially Tesla said I must have requested a change to the grid code to 99, but this was nonsense. I got the impression that the adviser was clutching at straws and didn't really know what she was talking about. Then a few months later they said it was a...

FWIW, I started a thread here: https://teslamotorsclub.com/tmc/threads/powerwall-overnight-charging-rate.314066/#post-8032529 to ask about the fact that my TBC charging rate had gone from 3.7 kW to 5.0 kW at the end of Feb 2023. Initially someone at Tesla thought it was to do with grid...

Sorry, I've been very late replying to this. I made another effort to contact Tesla Europe and this time they told me that it was a change of policy and that the 3.7 kW charging rate has been superseded by the 5 kW rate, which corresponds with the max charging rate of Powerwall 2. The...

Happened on this topic by accident, but am very grateful now to be able to say a big THANK YOU to tomho. The app version of Powerwall Companion saved my sanity in the early days of having a Powerwall, on my Android phone of the time the Tesla app didn't load reliably, and was *******...

We've had a Powerwall 2 for just over two years, and for the first eighteen months (until March 2023) we had five hours per night of cheap rate electricity on the Octopus "Go Faster" tariff. Throughout that period - when using Time Based Control - our Powerwall would charge at a rate of 3.7...

I'd buy you a beer xWren if I could. Quite right, well said. But I'm afraid I don't think the wretched Musk understands anyone other than himself being a control-freak. Or the simple common-sense practicalities you describe so accurately.

Stop digging Redhill-qik :) Many of us - perhaps most of us our side of the Atlantic - don't have many of these things, and certainly not networked. I have eight satellite receivers, but only two of them are connected to the network (and that almost killed me achieving that) and the...

Thanks for the detail. What I suppose irks me is that our installer gave the impression that my providing an ethernet cable to the Gateway was a deal-breaker; it would have been more "up front" if they'd said "please provide a cable, but it's not the end of the world if you can't...

With apologies to everyone for continuing somewhat off topic: Basically xWren we've gone from bad to worse. On my Motorola G Play the app is unusable, even after a re-install, and on a Motorola G (not Play) it's slow but usable, often crashes. Ongoing complaints to Tesla Europe now...

At the moment Hubitat are out of stock at Amazon UK but when they come back in it sounds like what I need. Thanks Tim-in-CA.

@ Tim-in-CA What you've achieved fascinates me, and I'd willingly order a Hubitat this minute if I thought I was clever enough to get it to work with the Powerwall! As I really am really really not well-versed in these things, you say that you need a Hubitat device, presumably by...

I've got problems with the Powerwall Companion app as of yesterday afternoon, on two different Android devices. Keeps asking me to log in, but then just shows a black screen, apart from the Tesla Powerwall logo at the top. As the "proper" Tesla app is incredibly slow to run for me...

.... which is precisely what I have been doing up to now, but in a much more amateur way than you xWren, involving waking up between 01.30 and 03.30 and then taking appropriate steps to adjust between TBC and Self Consumption and sliding the storm watch reserve bar around..... Just wish I...

Renewed thanks, I now understand. I must see if I can get our installer to do what yours has, ie get the monitoring in place by Solar Edge. It really annoys me that I can't use the computer to see what's going on (apart from the very basic direct-to-IP facility), and for me any sort of...

Thanks JohnRatsey. I am the first to admit I'm confused, and being a bit slow in understanding, but can I ask what the Solar Edge figures you linked to are if they aren't yours? I understand the PV Output site, in fact I tried to sign up to it but it asked so many questions that I...

@Gwgan - yes, very different, it's a real money saver being able to charge up at night on cheap rates during the winter and then use that energy during the day instead of drawing from the grid. My understanding is that you over in America - and I may need correcting on this - get some sort...

Thanks - but how do *I* get Solar Edge to monitor MY system in the same way that YOUR Tesla system is being monitored by Solar Edge? Or am I still missing something?

Thanks JohnRatsey, and for access to the graphs. I'm now going to ask what I suspect is a stupid question - if it's the Tesla algorithm controlling your system, how does Solar Edge come into it. What am I missing? I have access to a neighbour's monitoring system via Solar Edge - their...

Whilst I still don't trust my TBC an inch, and still regularly wake up anyway during the night and adjust it, as I said on 2nd March (upthread) I do think that it's making some rather better informed decisions, and like you JohnR I'm finding that it does seem to have moved away from the...

Sadly we're back to the night time charging making poor decisions - I trusted ours last night when it started charging on TBC at 0130, but should have checked later in the night when I woke up, as it stopped at 80%. Now we have a cold morning, a dull day forecast, and a battery that...

Thanks ST63. Keep us posted. In view of what's going on I ended my Octopus Go Faster (5 hour 0130 - 0630, 5.5 p / 16.25 p per kWh) six months early, switching to the "new" version of exactly the same tariff (same times, 8.25 / 31 .25 p per kWh) but fixed for a year. I checked with...

@ ST63 - how odd that your and my system are doing the opposite. Like you I'm not sure I'm up to the Raspberry Pi solution, I bought the kit but then gave up when other things got in the way. Have you put in £ values for your tariff on the app? I'm wondering whether the fact I put in a...

With regard to the Time Based Control, I am noticing that - since the system has been updated to allow one to put in the cost per kWh of each period of a tariff - my night time charging is behaving more sensibly. For example a few days ago we had two days on the trot of constant sunshine...

Thanks for the further comments. I can quite see that a lot of customers do indeed desire a "set it and forget it" installation, and I suspect that the charging-decision algorithm does work a lot better in places like America where the weather is less inclined - as we say this side of the...

@ mspohr Thanks - that's interesting. There's nothing critical in this house that really needs UPS protection, and your explanation is useful to know. Having what is a relatively quick change over suffices, and with the recent storms in Europe it's been a comfort to know that the...

@ Redhill_qik I think you've hit the nail on the head. In my case it's one control freak (Musk) meeting another (me). It's not a happy situation. But I am staggered that our constructive requests - all wanting the same thing - are being brushed aside. One had hoped that a company...

@ Ampster - Sorry, only just seen your reply. If you look back through this topic (at the British contributions) you'll see that we're all asking the same thing, namely an option for the user to control the forthcoming night's charge level before bedtime, so that by the end of the night...

Another question for any other British users: We've had plenty of opportunity with the recent storms to watch the performance of the Tesla Powerwall system during very short outages, and whilst it does keep the lights on it doesn't react sufficiently fast to prevent computers shutting down...

To add to my woes the Tesla app is now running so slowly on my phone that it's next to useless. It takes over a minute to load the current status, and trying to download each day's data is a nightmare if one leaves it for a couple of weeks and then tries to go back through the calendar...

After two days of sunshine on Thursday and Friday our Powerwall has started showing its algorithmic shortcomings again, although I "got to it" during Friday and Saturday nights to force it to charge fully, last night I woke at 06.00 to find that it had stopped charging at 75%. I managed...

I've just had the chance to have a go at Tesla via a survey that came through following installation of our Powerwall a few weeks ago. Whilst I praised the installation and hardware, I told them precisely what I think of the app and of the lack of control over charging levels overnight. I...

Last night it was at about 40% in the early hours. Leaving it on TBC it didn't start charging at the start of cheap rate (in my case 01.30 - 06.30). At 02.30 I slid the reserve charge level to 95% and off it went, briefly at 1.7 kW and then the full 5.0. I think it could have got up to...

@ xWren - I have much the same experience. I'm hoping to go down the Raspberry Pi route, but in the meantime I'm controlling everything by waking up at night and fiddling with the app. In self-powered mode it charges at 1.7 kW, however for the last two nights using TBC mode it did what...

Gdotp - that really does look like good news.

Having watched the video up to where he starts copying files (whose origin he doesn't explain) it then went way over my head. I'm not sure that I'm going to be able to do this even with help! (Laters - ah, I realise that the files whose origin I couldn't work out are in fact available via a...

Thanks Gdotp. I'll have a proper watch of it and come back to you, but yes I suspect that anything (like the CRON) that makes life easier for the person I have in mind to set this up for me would be welcome. Please give me a few hours to watch the video and I'll come back after that...

@ Gdotp I'm sure it would be beyond me on my own, but I have technically-expert friends who might be able to help - would you perhaps be able please to post what I assume is a link to the Youtube video you mention, which again I assume tells one how to do this....?

Heidi who answers the phone if you ring the Tesla helpline. I think she's in Holland probably, but it's the UK number. She also answered my email about it, and was very helpful on the phone over a smart meter problem we have (power leaking back to the grid at all times, about 60W...

I'm going to have another go at Heidi tomorrow, pointing her to this thread, and asking if she can let me have an address in the USA to email.

Ah - thank you.

Sorry you're still having troubleGdotp. I'm still controlling mine manually during the night...... How did you get the updated version of the app (4.2)? I've been to the Playstore but it only shows the current version that I already have......

A classic example Gdotp. Dreadful, irrational, and ultimately costly. And I thought discharging at 5 kW wasn't good for the battery. That said I suspect that Tesla would say that they emptied the battery to leave room for the almost 100% you got back from the sun during the day...
