That looks to have fixed that error, but we get different errorrs now

Sorry @reedy I made quite significant changes and obviously not a lot of testing here, can you try the “dev” version. I’ll try to combine these two later

[reedy]

Yeah, switched over now :)

Minor config changes needed, but looks to be up and running now again.

I should work out how to do the fancy dashboard things rather than just having the list of sensors

[kellerza]

Energy management is the first step - here (kWh)

The other one is the power-distribution-card that you can install via HACS. You can use it for displaying all the instantaneous power measurements (Watt)

It didn't crash though... :D
