Premium hardware, inferior software + firmware, and a "we always know best" corporate attitude. There is no easy way to know just how little control you will have over the Powerwall before you buy it, or how internet dependant it is. Pretty poor design of a backup device - when the power is out...

Jay I can only agree with you, and I have frequently moaned about the frustrating lack of control of a device I own, and what control I do have being internet dependant. The software is created by children that know nothing about resilient engineering or that the cloud is not always accessible...

@BGbreeder looking at my winter data (high use, low solar) my peaks in consumption are around 6kW, less than half the 14kW I have to play with. If Tesla would give me the control I can manage my resources really efficiently

No aircon or heated pool.... our electricity use is very moderate compared to so many of the graphs I see on this forum. But lack of owner control of devices is an issue, the big corporation and the software they design does not know best and is not able to predict my use.

Nope, single phase, and 60A seemed more than enough when installed. Now if they continue to incentivise small windows of cheaper electricity, then I do need to be able to manage the rate things consume grid power and/or time when they do that.

The random erratic behaviour when charging in Time-Based mode continues. Some nights are fine and others do things like this: The mystery drop to 1.7kW as if it is in self-consumption mode, this time for 20 mins. My internet was working fine, I happened to wake up and check during that 1.7kW...

@mw963 my understanding is that Powerwalls in the UK were by default throttled to 3.7kW by a setting configured by the installer. This limit was to match the OffGen rules that allowed equipment that could output to the grid (solar panels and batteries) to be installed without additional...

Yes Battery SOC has reappeared now, it sounds like Tesla broken something their end for a while.

@tomho I'm seeing an error on the Windows UWP version this morning, and not seeing battery SOC

I created a Third-party developer account with Tesla yesterday, but my attempts to request access for app credentials using valid business details got the immediate error "Unable to Onboard, Contact your account manager....". I suspect my current lack of a web page is the issue, I have a domain...

Interesting, I'm in UK also and get 3.6kW (the supplier limit in and out unless permission gained from the DSO) in time based mode and 1.7kW in self-powered. So curious @bruce_miranda that you see 2.34kW, what firmware version are you on?

Thanks for your input @offandonagain . I do have a tech business I could register with, however I don't have a website any more nor do I have an oAuth provider, and both seem to be necessary aspects of gaining permission and getting FleetAPI working. Have I understood correctly? Just how many...

Sorry @Vostok,possibly a false alarm on my part. My scripts are based on Tim Drossers TeslaPy and had unnecessary use of api/1/vehicles endpoint. That endpoint is what vanished over night, so I can get around it. But it has kicked me in the pants to look at swapping to Fleet API, just not sure...

I've been using the Owner API to control when my Powerwall is charged from the grid, using Python scripts based on TeslaPy running on a RPi. This API is being turned off this year so I will need to move to using the new Fleet API. I'm hoping that some of the app developers and script writers...

Well @Vostok my script (setting mode and backup reserve percentage) using the Owner API failed this morning with "HTTPError: 412 Client Error: Endpoint is only available on fleetapi" so I'm looking at how I get permission as merely an owner to use the Fleet API. At 00:30 GMT scripts ran just...
