Any progress on this ?
I'm thinking of using RPI4's built in Bluetooth to connect to the EPsolar charge controller and the batteries' Bluetooth interface.
(I hate pulling cables around the boat
).
What I have gathered at least the EPsolar controller uses Modbus protocol for the Bluetooth communication.
It should be possible to program the built in Bluetooth to connect to the controller, batteries in a round robin fashion and download the
current data and forward them to SignalK and display the results on a page, could be a tab only for charging and power. Possibly storing
battery status in the influx database.
I have not see references to such a project, this is a common topic and should be a simple programming only project with no extra hardware since all
are already present.
