Would it be possible to add support for the BMS used in Epoch / RoyPow batteries? These are gaining a lot of ground in the RV space and it would be great to be able to monitor them!

I have a few of these batteries and would be glad to provide any info needed from them. Thank you!

Do you have more information about the battery? Which BMS do they use, an app, a Bluetooth trace, ... ?

[rubenclark74]

I'm not sure which BMS they use, but I believe it may be their own. The app is 'Epoch LI-ion'. Here are a couple of screenshots:

I haven't done a Bluetooth trace. Is there a particular app that works well for this?

Yes, the template you filled for the request gives you hints for additional context: 😎

Add any other context (documentation) or screenshots about the feature request here. For new BMS types, please provide the output of bluetoothctl info <MAC> and the service explorer script. To speed up the integration please see if you are able to capture the Bluetooth traffic on Android or iOS while using the vendor app with the battery.

Thanks, Patrick
