Solution in case address 49 does not work #4

Just in case someone faces my issue, I had to set INT49 on the koolnova master remote but address 1 on homeassistant configuration, koolnova customer support helped me in that way, now the communication works.

Feel free to close the issue as it's solved

Hi Mauro,

Glad to see your setup works with this. I modified the README to warn future users. I have always configured the default koolnova address on my installation without encountering any problems. The official documentation says : "System address : Each control unit has a specific address (default 49). Possible addresses are 1 to 247, so you can put up to 247 control units in a parallel-connected project"

There is a modbus register (40078 in Read/Write) that set/get koolnova modbus address. this integration doesn't interact with this register. Maybe this address was changed in your controller ?

Maybe, it was installed by a third party I didn't install it by myself, so it is possible they reconfigure the controllers. Anyway thanks for the update in the readme. I hope that could help other people too :)
