Hi,
if the Selectronic inverter can 'speak' the Pylon protocol then it should be no problem. Otherwise I would need a CAN communication specification for the Selectronic.

And your setup would be the JK BMS -> Selectronic inverter right? Or JK -> Fronius? I got a bit confused reading ;)

Sorry, a lot of inverters. JK to selectronic is what I am looking at. When I contacted Batrium about their bms (they advertise compatible with inverters that speak pylontech) they said they had issues with selectronic not working and wouldn’t guarantee it would work. Where would I find a can communication specification? Sorry, I did say I am a noob :)

thanks for your prompt reply

Ah ok, so you can test if you get reading using the JK BMS binding (choose JK_CAN in the Configurator app). For the test please enable debug log-level and as inverter choose NONE for now.
Which CAN hat do you have for your Raspberry PI? If none yet, I would suggest the Waveshare 2CH CAN hat as you'll be needing 2 can ports (one from BMS to RPI and one from RPI to inverter).

NOTE: We have discovert that the Waveshare 2CH CAN hat does not (currently) work with a RPI 5. If you want to buy a PI for this project I would suggest to go with the RPI 4B for now.
