Hi, I try to connect a Kaco 6TL3 to Venus on a Pi 3. The connection starts ok, data are correct but after a time it fails.

my log is below.

THX for help!

I can neither say why the kaco inverter terminates the connection, nor can I accept this MR.

I made it wrong, this was "Unit 1", with "Unit 2" I get this

any idea?

DbusKaco - ERROR - regs.isError: {regs} Try debug/print out the that line and check what error exactly "regs" ( +str(regs) ) is. You need to fix the register numbers for your inverter based on the documentation of it.

ok, I will try thx

Modbus adresses where ak, alft updateting Kaco from 3.2 to 5.5.7 it seem to be working.

Sorry for disturbing you.

Well done, thx BR Guenter
