could not get mqtt value

[ExPalm]

Hello Sieren,

thank you for this very nice project. I could run switches by using the ArduiTouch device but unfortunately I could not find a way to show values from my ESP sensors. I use Mosquitto as MQTT Broker. Devices are sending from FHEM and I can get the values with an ESP/OLED device but I could not find a way to confinger the config.json tho get the values on the AduiTouch.
For example I can get values by using other devices by using the gettopic /draussen/temperature. When I put this topic in the
config.json like this
"type": "singleValue",
"firstIcon": "temperature_small",
"jsondata": true,
"firstKey": "Temperature",
"getTopic": "/draussen/temperature"
I get only 0 displayed.
Do you have a hint for me?

Thanks

In this particular case, what does /draussen/temperature actually return? Is it a JSON String (e.g. { "Temperature": 12 }) or the raw value?
If it's the raw value, you need to remove jsonData and firstKey from the config.

Are you sure your MQTT topic is /draussen/temperature? MQTT topics normally don't start with / like file paths.

Here is a screenshot from MQTT Explorer. It looks for me like a raw value but when I remove jsonData and firstkey only the icon is shown on the display.

It looks to me its a combination of what @koenvervloesem and I said.
The path of this topic is a bit odd to me too. Is there a blank space before the first / ?

[ExPalm]

No there is no space in front. Here is a screenshot from FHEM where I defined the MQTT Bridge

Even when I take off the first / there nothing displayed only the icon

Thank you I got it. It was the issue with the raw data. Thanks a lot and enjoy the coffee

[Matt Sieren]

Nice! Glad you got it sorted. What issue was it exactly? Always keen to learn in case someone else has this issue

[ExPalm]

The hint to remove jsonDate and firstKey when only raw data are transfered was the solution
