Lost connectivity after installing a comfoclime cool

[maschbaer]

Hello,

I have been using this HA Plugin since 4 years without major issues to have advance control over my Q450 e.g adjusting the fan speed depending on day time, humidity, presence of residents.

However, since I installed a ComfoClime Cool 24 on top of my Q450 the HA plugin does connect to the Q450 anymore. The comfocontrol app connects normal. The IP and pw of the comfoconnect are unchanged.

As soon as I unpower the ComfoClime Cool the plugin reconnects to the Q450.

Any idea how to fix this?

Regards, Jan
