Problem with OpenHAB Mycroft skill

Tags: #<Tag:0x00007fe72e32db20>

I’m using mycroft openhab skill, it works well with switch on/off lights, but I have a problem with dimmer

13:09:28.271 - mycroft.skills.core:wrapper:1102 - ERROR - An error occurred while processing a request in open HAB Skill
Traceback (most recent call last):
  File "/home/pi/mycroft-core/mycroft/skills/", line 1093, in wrapper
  File "/opt/mycroft/skills/openhab-skill.openhab/", line 208, in handle_dimmer_status_intent
    if ((int(brightValue) < 0) or (int(brightValue) > 100)):
TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'

It seems he is trying to send 50% instead of 50.
If I issue a command set dimmer to 50 it works, but if I say 50 percent it doesnt work.

Dimmer        LivingDimmer       "Living Dimmer [%s %%]"               <light>                        ["Lighting"]                { channel="knx:device:bridge:generic:LivingDimmer" } 

How should I configure the item?

Also, when I ask him for what is current living room temperature, he says 36 degrees (he gets outside temperature from the internet, completely ignores the item

Number        RoomsTemp          "Living Room Temperature"                 <temperature>                  ["CurrentTemperature"]      { channel="knx:device:bridge:generic:RoomsTemp" }
