@benderl AFAIK the Smart Battery Sense really only has the voltage and temperature properties, so only these should be listed in the documentation.

Should I add another doc file for my battery monitor "BMV-712"?

[DigiH]

I already submitted that with my previous commit

https://github.com/theengs/decoder/blob/development/docs/devices/Victron_BM.md

but just realised that it should have an all caps name to be consistent with the other Victron docs ;) - Done

Ok, removed the doc change.
