Can't control Itho via Homebridge

[prutsky]

I enabled the plugin on homebridge and filled in all necessary fields (MQ. After this, I added the homebridge hub to my "Home" on my phone. The hub is recognized and an air quality sensor and fan is added.
After this the fan is running at 47% according to "Home". In the Add on web interface it is set to value "120".
When I wan't to change value/speed of the fan, nothing happens, although Homebridge does show the value change.
The fan stays on the same speed, the Add on webinterface doesn't show the speed change either.

Note: I did not connect my RFT-N AUTO remote to the add-on.
