Im working on a homey EMS system that will calculate the solar production of tomorrow in order to plan its strategy to load home batteries and charge your car. First approach is to connect EV’s in general and Tesla, Batteries planned is Marstek. Solar production kan also be monitored by homewizard. …

This would immediately supp…

Yes that is a very nice app indeed. Also an inspiration on how to develop this one. User interface in homey is limited but the rest should be similar to evcc, perhaps on some points easier. evcc needs to make a lot stuff to make all the different devices work, in Homey devices have their capabilitie…
