Tags: #<Tag:0x00007f5c966fefd8> #<Tag:0x00007f5c966fef10>

I have to monitor and control my heat pump havc system.

Brand “innova energie”
Comunication protocol for heat pump, convector and web server Is MODBUS RTU/TCP.


HAVC Webserver is “Web Server BUTLER ESW544”.

I would integrate the HVAC system on openhab

Some suggestions ?

I have to binding with MODBUS or I can communicate with TCP/IP protocol directly to the HVAC server ?

Hi, i have the same request. I need to connect INNOVA ehPoca with openHab. I control this heat pump with native tcp protocol Butler.
