Gen3 Wall Connector API?

[rrlevy]

Did anyone found out a way to EDIT settings on the Wall Connector via API?

I was hoping to be able to change the max current, but since the web interface requires you to manually click the connector or turn it off and on, I haven’t been able to automate this

Tesla Wall connector API has some pretty significant flaws. For example the TotalEnergy attribute is constantly giving false information. I've got days when it just jumps by 200+ kWhs, which is impossible, because the car cannot hold more than 70 kWhs, I never charge it to 100% and my house meter does not increase by more than 40-50 kWhs that day.

This is not an exception, this is happening regularly. I think the wall connector's API is similarly buggy as Tesla's software in general (door locks, windshield wipers, phantom breakings, etc.) Probably that's why they don't publish the API because it's just not ready to use.

I'm sure the reason they don't publish is because they don't want all the hassle that goes along with it. They have to keep it up to date, they have to notify people of changes in advance, etc...

I've got a bunch of these at my office and want to start querying them so I can see if they're in use or not. Share a visual for people at the office so they can see when what chargers are available. Excited to dig in to this.

Boy I wish there was an easy way to set amperage via the API. I'm going to have to get an OpenEVSE and use the Tesla cord if something doesn't change. I don't believe in using cloud tools for things that can be abused, but I need to be able to manage charging so that when the dryer is running maximum charge current is reduced. (I charge at 24A without the dryer and 18A with to stay within my power budget of the PV system.)

Have I mentioned TesSense.py? It talks to the car and adjusts the power the Tesla charges with from Any EVSE. It's designed to be used with a Sense Energy Monitor, but it can be modified.

Or Charge HQ, that works with lots of hardware.

What do you mean by "I don't believe in using cloud tools for things that can be abused?" The Tesla cloud talks to your car whether or not you use the Tesla API, so your use of it won't add to any vulnerability that exists. Might as well use it, as it will solve your problem easily.

I wonder why Tesla hasn't added the Wall Connector the app yet. This information is awesome and really helpful in understanding how much it's costing to charge at home.

I'm going to shoot you a PM, if that's okay. I want to discuss this further.

Anyone found a comprehensive list of status numbers? I've seen a few different sources, but nothing very complete. I know 11 is charging. 4 and 9 are disconnected?
