Directy after installation but already before the required (?) restat (at least HA told me so), Battey Notes discovered some devices.

But unfortunately only a few. A lot of others, which are in the battery library as well.

Is there a force discovery or have an idea, why so many batteries are missing?

Even on manual add it seems, that they are not in library but according to the list, they should. Some of many examples:

Hi, thanks for the detailed information, this allowed me to track this down easily.

This is a bug introduced recently. Because the library does not have the Model ID it does not match, this shouldn't be the case, it should find the library one without the model id specified.

I'll work on a fix for this.

@andrew-codechimp Your fix is working. Found now many many additional devices and added the helper.

Thanks and best regards!

Not only related to Homematic devices, but epaper, Sonos, etc. as well.

Thanks for confirmation, I didn't anticipate you grabbing the code directly. I'll include it in a release in the near future.
