I noticed today that I was exporting to the grid even though the battery was not full. I’ve had set up the utility rate plan to have an off-peak buy price (0.05)and peak buy price (0.15) but NO export prices. However I suspect there is a bug as with this config the power wall WILL export. I’ve...

I hope not! It did start charging the second the script ran and when I tested it earlier in the day it started immediately and stopped immediately so I’m hopeful. I’ll report back on tne next few days of usage. I’m on 21.35.0.

I’ve been using time based control as the default so this solution works well as it simply switches the power reserve level from 0 to 100 and back. Doing this charged at full rate last night so it was more than enough to to fill it in the 4 hour slot. I also like it as it’s controlled with CRON...

Of course. This is the link: It’s actually very simple and these instructions are pretty good and even show how to set up the pi. I set up a pi zero in “headless” mode rather than 3/4 because it’s really really cheap (less than £10) and I had one in the cupboard, a 3 is about £35 if you have...

I’ve implemented a manual work around on an old pi zero today from Git and yotube that manually switches between Tou and backup during my off peak period. A simple Cron schedule Runs it . I’ll. See how that works tonight and report back. I’ve also submitted a ticket to Tesla to ask that they...

Heidi who? I’m going to start to contact Tesla on this as the more pressure we can put on them to address this the better.

I’m on iOS but the only change appears to be the version number. I’m trying at the moment to set up a raspberry pi so that I can automate goi g to backup mode during off peak times.

I’m in the U.K. and on v4.2. My app however does not have the ability to set the cost of each rate plan. The last week the system has been HOPELESS at predicting any usage vs generation getting it wrong every single day. My off peak cost is 3 times less than my peak so I was hoping setting...

Thanks for the tip on storm watch but I’ve disabled this as I wanted it to avoid topping up with peak electricity for no reason. I’m not sure I do misunderstand it. Even if it did look at my previous days consumption it’s not working. The consumption is pretty consistent day to day and it...

Even worse. It did not learn from yesterday, only charged to 7% off peak and ran out before the sun even came up. Currently sitting at 7% because it’s dull again today so we will tun out soon after the sun goes down. I’m starting to think the powerwall is pointless.

It’s even worse today…..it was forecast to be dull and cloudy ( only 7kw generated all day) so you’d have thought it would have done a precautionary top up off peak but not it did not. As a result I’ll be out of charge by 7pm

An example of the issue and dumb algorithm. Last night in the off peak period I was charging the car. For some inexplicable reason the battery decided to dump its remaining charge at the end of this into the car leaving it empty at just after 04.30 even though it was forecast to be a pretty...

Thx. Me neither

Hi are you sure it can’t charge at 3.4. It looks like mine did the other day and I’ve certainly seen it get to 90% in the past. See below. The usage shown is 3.6kw but I’ve got an overnight load of 200 to 300w. Could you share your RPi script, I do t have the skills but can probably tinker...

3.5 *4 = 14 in theory but you can’t force it to do this as it’s down to the so called AI to do it. You can influence is by setting the off peak period and if you are dedicated by setting the minim charge level at 0.30 to 100% and then back down again at 04:30 manually (octopus Go) The biggest...

I could not agree more. It seems like such a simple change. Due to yesterdays issues we ran out of charge at 7am and by 8pm we will be out again.

An example of how brain-dead the Tesla algorithm is….at least in the Uk where we have weather. Last night it decided not to top up in our off-peak period starting at 00.30. I presume because the previous day we had a bit of sun and it had topped up the previous night to 50% meaning it was full...

@xWren id be very interested in trying your Pi code out if you could post it to Git. I’ve already a couple of Pi’s about the place and I’m getting a bit fed up with the brain dead Tesla code making incorrect assumptions of the next days generation (if that’s what it dies) and getting it wrong.

Thanks for the update.

I’m sure someone has spotted this but the graphs don’t contain all the data. My iPhone seems to randomly cut off each days collection but the same view on my iPad shows the full day (usually) iphone Ipad
