Description

The app is based on discovered APIs → Tesla Motors Club
The APIs from the changer can change without any notice and the APP will need to be updated when changed.

Supported Devices

  • Tesla Wall Connector Gen 3

Limitations

  • The TWC can’t be controlled.

Development plan

I welcome anyone to join the project and help with the development, send me a PM and we will find a solution.

Phase one:

  • Set up the device with all capabilities, the chargers deliver a lot of information.
  • Get good names on the capabilities, names that make sense.

If you see any names that should be changed, please leave a comment.

Phase two:

  • Add Triggers
  • Add Conditions
  • There will not be any actions as there are no
    control APIs available for the charger.

If you have any requests for triggers or conditions, please leave a comment.

Phase three

  • Translation
  • Adding new features if Tesla exposes more APIs for the charger

Bonus

There could be a way to control the max power of the charger, TWC3 Interface, if someone wants to help this can be something :smiley:

Any feedback is welcome :blush:

Great app! Finally being able to read and use the data of it!
Pretty shocking to see there is a difference between the Shelly EM that is connected to the charger (3250 kWh) and the total energy being read from this app (3600 kWh)…

It would be useful if we could use the current charging power W as an indicator for the device icon, it’s the only one that isn’t available in the list.

Thanks!
I use custom capabilities for power and voltage to change the icons, Homey should support them. I need to figure this why my custom capabilities are not usable as indicators.

New v1.4.2 is out in test:
Should be possible to set all capabilities as status indicators, you probably need to remove and add the device again to make them visible.

Thanks!

Hi.

Is it possible to stop&start charging or only read data?

Hi,

It’s not any possibility to control the TWC, it currently only delivers data.

Hi

A new version is out in test v1.4.3:

  • Added more data from the TWC.
  • Change names for some of the capabilities to make them a bit more clear
  • Removed Norwegian translation, as I will focus on the English part first.

The next step is to add triggers for the charge and contractor state.

When that’s done I’m open to suggestions, so please let me know if you miss something :blush:

Hi all,

I moved the source from GitLab to GitHub.
Renamed the app to “Tesla Power Connect”, as to not confuse it with the Tesla Inc brand name “Tesla Wall Connector”

Hi all,

There seems to be an issue with the voltage reported for the TWC with firmware version 22.41.2+gdb42f98c0aafdd (Voltage bug on 22.41.2 Gen3 HPWC Firmware? | Tesla Motors Club)

I’m with test v1.4.8 I’ve added 10v to the power calculations, and this seems to work for 230v with three phases. I’ve not changed the voltage values shown in the app but will do so when I get confirmation about the new power usage calculation.
