Temperature rule does not fire

Hello, my name is Bastian and I just started on Openhab. In my first little setup I am using a Shelly H/T via MQTT (internal broker) and a Homematic IP thermostat (HmIP-eTRV-B) via Rasberrymatic. I am getting values and am able to control the thermostat via sendcommand in the console and via BasicUI. The next step was to create a rule that will turn on the thermostat, when the temperature from the shelly drops below a value.

Here is my configured rule and item:

//Shelly H/T
Number:Temperature StubeTemp “Raum Temperatur” (LivingRoom_GF) {channel=“mqtt:topic:8be44631:Stubetemp”}

Number:Dimensionless StubeHumidity “Raum Luftfeuchte [%.1f %%]” (LivingRoom_GF) {channel=“mqtt:topic:8be44631:Stubehumidity”}

Number:Dimensionless StubeBattery “H/T Batterie [%.1f %%]” (LivingRoom_GF) {channel=“mqtt:topic:8be44631:Stubebattery”}


//Thermostat Stube Homematic
Switch Stubethermolevelsw “Ein/Aus” (LivingRoom_GF) {channel=“homematic:HmIP-eTRV-B:3014F711A061A7DA498F9F9A:00201BE99339CC:1#LEVEL”}

I found a simple rule in the turtorial which I wanted to test


rule “Stube_temp”


Item StubeTemp received update


if(StubeTemp.state < 26) {



else {




When I mouseover the items in Visual Studio Code I can see the correct values and states.

I tried to change StubeTemp via the console to 22. smarthome:send StubeTemp (22) but nothing happens. When I send smarthome:send Stubethermolevelsw ON the valve is opening to 100.

Here are some eventlogs:

Thank you for the quick answer @rossko57, that did it. I was totally looking at the wrong places :blush:
