I have Solar Power which uses Fronius Primo Gen 24 Plus so has the Datamanager and the SolarAPI available. It also includes a Fronius Smart meter so all import and export data is available and I have a few BYD HVM batteries. I currently use HA for controlling the use of excess Solar to storage heaters and it is working brilliantly so I hardly export much at all.
I am also on Octopus and it may be a forelorn hope that at some time they may get my Grid Smart Meter working and then I may be able to move to Intelligent Octopus Go.
I now have an EV on order and I want to know which offers the best Open source integration into Home Assistant now in 2023 and is available for install in the UK? Looking around there are an amazing number of EV chargers available, many of which offer ‘Solar Ready’ but I really do not believe that it means Solar and battery ready. Their systems just seem to offer a current clamp that monitors export but I need higher level of control that can dynamically prioritise and say, have Immersion as number 1, house batteries as 2, car as 3 and storage heaters as 4. Or perhaps in winter just charge the EV from an ecomomy night rate.
From my research so far it looks like Easee, Zaptec and Hypervault are the front runners as they seem to be best for integration, having PEN fault protection included and have many installers. I had initially thought that going with the Fronius Wattpower would be the obvious choice but it doesn’t incorporate PEN fault protection so looks like an expensive untidy option. It may not be mainstream enough for Octopus tariffs as they don’t even list it as an available charger even as an incompatible one.
The number of OCPP EV wallboxes seems limited but is this going to be the future for home units?
Does anyone have direct experience with what is available now and can recommend what will work best for me ?
