Switching Optimizer Sensors
Unfortunately the current evcc implementation will switch the objects for the different batteries, depending on the connection state of your vehicles - currently there is no real solution in the HA Integration to detect this switching dynamically and handle it generally - so you must handle this in your local templates.
Therefor the new release will add the attributes name, type and capacity (also title when available) to the attributes of the three optimizer sensors that have been introduced with https://github.com/marq24/ha-evcc/tree/2026.1.2
Please consider supporting me
Thanks to those who have already supported me in the past weeks or month that is highly appreciated! To the other users: I am putting quite an amount of energy and passion into this integration. Perhaps you could give yourself a little push (if you can afford it) and become a sponsor.
If you haven't starred this integration in Github yet - please do so - TIA
