Hello All! A climate sensor provides CO2 data via MQTT. The basic data of the sensor added to configuration.yaml: mqtt: sensor: - state_topic: "homeassitant/sensor/co2meter/c" name: "CO2 Meter" unit_of_measurement: "ppm" value_template: '{{ value_json.value | int }}' I h…

Solved: With this data inside configuration.yaml it finally works. The unique_id is essential to access and use it inside Home Assistant. An additional weakness of the sensor is, that it truncates the length of the state_topic string. It must include a individual name, the keyword “sensor” and the …

Hello, thanks for the reply: attached a screencopy of “Home Assistant/MQTT/listen to topic”: [Screenshot 2023-11-30 121111] In MQTT Explorer it looks similar (the payloads are integers) and each sensor is a seperate topic. The data of the sensor is available, however I found no way to get it as a…

A rule running on the Tasmota device publishes the data as a single topic:value pair. Unlike other topic messages with many components that display within “{ }” in JSON format the “L…

If there’s no json in the message, then just use value. value_template: '{{ value | int }}' Or just leave the option value_template out? Not sure, try it.

Using just value worked. Thank you

Hello, I first changed the value_template and in a second step I commented it out - however no change - still no change in the number of the entities of integration MQTT. How did you made use of the new measured value? Cheers Uli

I think this is wrong

think the json value is missing some data

should look something like

"{{value_json['array_name'].its_data_point_you_reading }}"

need to see the json message
