I built this: Charge the car and ignore energy prices if there's an appointment coming up

TLDR;
Problem:
You charge your car automatically when energy is cheap(great!) but you have a scheduled appointment and need a “fully” charged car in the morning, no matter the energy cost.

Solution:
Check Battery level and calendar events daily and force charging if needed!

So, my GF has to travel around 150km per day if she plans to work at the office and not at home.
At the same time, the car is only charged if energy prices are low - that could lead to the car hanging around at 25% for 2-3 days.
2 office days in a row are no problem, 3 become an issue. So I built this automation to check the calendar for events that have the office’s location set and then force charge the car and ignore energy prices, if necessary.

this automation uses:

  • the calendar integration and our shared calendar events
  • the Wallbox API, a go-e charger
  • the Tesla integration to check battery level and set the charging limit
  • a proximity sensor to determine if the car is even at home
