Thanks for the answer.
I found the problem. You have to hold the TCP connection open that the charger recognizes the command.
But I habe an oter modbus related problem.
I have also running a server on th LM
It works as it should but at the input registers only register 0 to 425 can be read, at the higher registers I get a ilegal data address error back.
Is there a limitation?
Thanks

knxclient:step()It works as it should but at the input registers only register 0 to 425 can be read, at the higher registers I get a ilegal data address error back.
Is there a limitation?
Thanks
