Problem with Alexa Skill/Homematic 105155 Funk Heizkörperthermostat


(jb) #1

Hi, i have problems to control “Homematic 105155 Funk Heizkörperthermostat” with alexa.

  • Device is found in alexa
  • The Device get the commands and set the temperature

But in most cases Alexa says “The thermostat just not responding”

Group gWohnThermostat "Wohnzimmer Thermostat" ["Thermostat"]
Number WohnThermostatCurrentTemp "Wohnzimmer Thermostat Aktuelle Temperatur" (gWohnThermostat) [ "CurrentTemperature" ] { channel="homematic:HM-TC-IT-WM-W-EU:c74b6b1f:LEQ1056617:2#ACTUAL_TEMPERATURE" }
Number WohnThermostatTargetTemperature "Wohnzimmer Thermostat Soll Temperatur" (gWohnThermostat) [ "TargetTemperature" ] { channel="homematic:HM-TC-IT-WM-W-EU:c74b6b1f:LEQ1056617:2#SET_TEMPERATURE" }
String WohnThermostatHeatingCoolingMode "Wohnzimmer Thermostat Heating/Cooling Mode" (gWohnThermostat) [ "homekit:HeatingCoolingMode" ]

The state “WohnThermostatHeatingCoolingMode” is set to “HEAT”

Any ideas?

Did you use homekit and homematic things?

I’ve got it working for lights through the Alexa Binding but can’t help for thermostat though as I’ve connected directly to my nest. Looks like the tag may be missing?

I deleted the devices in the alexa app and search for new devices.
It worked for several times and i get the current temperature for the room.
Now it stopped working again…
But i never can change the TargetTemperature with Alexa… :frowning:

Switching Devices working without any problems…

Switch sw_it_tv “Multimedia” (gWz) [“Switchable”] { culintertechno=“type=raw;address=0F0F0F0FFF;commandOn=FF;commandOff=F0” }
Switch sw_it_wz1 “Steckdose links” (gWz) [“Switchable”] { culintertechno=“type=raw;address=0F0F0FF0FF;commandOn=FF;commandOff=F0” }
Switch sw_it_wz2 “Steckdose rechts” (gWz) [“Switchable”] { culintertechno=“type=raw;address=0F0F0FFF0F;commandOn=FF;commandOff=F0” }

Nobody any ideas ? Where can i found logs for this problems? Can i increase Log Levels for this problem ?

My nest item is as shown:

Number dining_room_target_temperature_c "Temperature [%.1f °C]" <temperature> { channel="nest:thermostat:c1c98214:xxxxxxxxxx:set_point" }

Yours doesn’t seem to have the tag - does that help?

Does it work via OH w/o Alexa? If so perhaps a workaround would be a virtul number item linked to alexa and linked to the thermo with a rule? Clumsy but would work.

Unfortunately not, sometimes it works but sometimes and very often not. So i think the binding is correct. It seems, the openhab Cloud responds too late…
