Warning since updating to Homebridge 1.3.0
Hi, I See this error in Homebridge log since I upgraded to 1.3.0:

[22.2.2021, 20:15:16] [homebridge-homematic] This plugin generated a warning from the characteristic 'Target Temperature': characteristic was supplied illegal value: number 5 exceeded minimum of 6. See https://git.io/JtMGR for more info.

It appears when I turn off the heater in a room via home.app. If I turn them off this will set a temperature value of "5". I didn't find a way in Homebridge or Homematic to set it to 6 via home app. It seems like there is a wrong value in the plugin. 

I am not sure if this is a plugin issue of if I have to configure something in Homebridge or Homematic. I searched for this problem and I searched for a changeable value in both applications but didn't find one. This error started appearing in 1.3.0 and disappeared when I reverted back to a plugin version below 0.2.
