Hi @marko2276 , thank you for your great project. I have been testing it in my house installation since it was published, and it works bug-free and really fast (pressing buttons - DI Inputs -Automation HA - RO without noticeable latency). Can you possibly say whether there is the possibility of integrating Modbus in the near future , because I am now dependent on the extensions due to the installation(;.

Thanks in advance,
Manuel
