Hi
I am using Home Assistant and thought I would share what I have done so far (more incomming)
I have an adaptive charge for my batteries based on a prediction of solar and a simple algorithm based on historic performance
I then dynamically take the entire system off grid when charged. The system returns to on grid when the battery falls either too low or too high (for some export)
I have auto configured the EV Charge Station to revert to auto mode but will give overnight full current charging during cheap night electricity rates
I have a colour light strip that changes scene based on the solar system (battery SOC + Excess Power + absolute power draw)
The Charge Station will also slowly charge the car in the evening (after the main draw of cooking etc) if the car will not be fully charged overnight during the cheap rate (this is still testing so I wont post the code as it may change)
Then I display many many parameters of the batteries/solar/etc
Hopefully this is of use
Any other fun automations always welcome
Cheers
