feature request: kWhDelivered/kWhCounter in WebUI, HASS status and MQTT

I’m working on a solution for a simple view of the consumed/charged kwh, preferably recorded by car/model (M3 and non tesla), just to get an overview of how much kwh each of the cars consumed in a year.

I think this fork is the closest to beginn with and fits quite good, as my idea was to integrate it in HASS anyway and/or make it available via MQTT.

I use TWCManager in a passive way, in fakemaster = 2 mode and like to capture the consumed kwh (on newer fw). As a second step I’m planing to readout part of the VIN to figure out if its a telsa or not to assign from-to charged kwh to the individual car.

is it possible to integrate kWhDelivered/kWhCounter msgpart from debug output in HASS and MQTT the same was as “total_amps_in_use”, “totalAmpsInUse” ?

@nean-and-i, to your last question, if a non-Tesla car is charging the result will be all zeros.

With 6365098 we add VIN polling for TWCs which support this in their firmware. When a vehicle is detected charging on a Slave TWC, we will send the command to prompt the TWC to send the first 7 bytes of the attached vehicle. If it responds, we then go on to request the next 7 bytes and finally the last 3 bytes.

This is stored as current VIN and last VIN for each Slave TWC. This is now visible in the built-in web interface, and is published via MQTT and HASS:

• last_vehicle_vin or lastVehicleVIN per TWC
• current_vehicle_vin or currentVehicleVIN per TWC

I am going to use this opportunity to do some work on the two Status module docs pages now to reflect all of the various published values. They are:

• https://github.com/ngardiner/TWCManager/blob/v1.2.0/docs/modules/Status_HASS.md
• https://github.com/ngardiner/TWCManager/blob/v1.2.0/docs/modules/Status_MQTT.md
