New HA Marketplace can have update issues
With the recent integration of former HACS into Home Assistant as default Marketplace integration, you run into difficulties while trying to update this integration. I have prepared a short documentation that will help you to identify and solve the current known issues here: HA_UPDATE.md
Migration from voluptuous to probatio
If you does not have a single clue what this means, your life is probably way better then mine.
This migration is really just internal technical stuff deep inside home assistant. Without going to deep into the details: it is about the format in which an integration can specify the input-form for the configuration of an integration. The change was already introduced in HA 2026.09 and there was full support for backward compatibility between (previous) voluptuous and probatio Schemas. But since the weather was lousy I decided to polish the integration a bit and make it a bit more future proof.
Please consider supporting me
Thanks to everybody who have already supported me in the past weeks or month that is really highly appreciated! Sometimes it has been a though journey so far. To the other users of this integration: 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 are using this integration for a longer period and you are satisfied, I would kindly ask you to go to https://github.com/marq24/ha-evcc and click the star button in the top right corner. This is the easiest way to support me and my work – and it costs you nothing (of course, this only apply if you aren’t one of those 502 people).
