I'm using a EASUN ISolar-SMH-II-2.2K inverter as the power source in my camper. This seems to be a axpert mks clone, it can be configured with WatchPower software, etc.
The camper does not have wifi, internet, etc. but I have suited a nice android tablet especially made for cars as my central radio set and navigation system.
Now I want power data (solar and battery voltage, solar power, etc.) on this tablet as well.

Off course I could install a RPi clone that connects to the inverter and collects data, stores it in a database, create nice graph's, but in fact I don't need that much.

I consider adding a serial2bt adapter to have a virtual serial connection to my inverter. What I miss is a android app, that connects to that BT converter and queries data from the inverter, just like watchpower does.

Is there any known product or homemade app out there? I found some posts on github regarding Axperts and BT, but it seems nobody really finished the work.

Honestly, Solar Assistant is what you're looking for but I've yet to see a free /open source alternative that's easy to set up and fuss free to work with
