Reading Powerwall / Solar

I was wondering if anyone has tried to tie into a Tesla Solar & Powerwall system where it stores the excess electricity in the car instead of sending it back to the grid. Solar Priorities should be the following during day: 1. powering the house 2. Charging the powerwall 3. Charging car. At night: Powerwall charging car with max 25% of his capacity. Has anyone figured out something similar?

Yes, here is a python script to grab data and send to a MQTT server to do exactly what you describe. On OpenEVSE you would enable Eco mode - Solar divert and the station would follow along.

The script prioritizes filling the Powerwall until it gets to the target State of Charge Default is 90%, then the Vehicle gets all the excess production.
