I am trying to create a gauge based off the lux value of the MQTT feed from a camera. When trying to add a gauge I see the message as follows: Entity is non-numeric: sensor.office_lux
Here is what I get from the camera
{“lux”: 9.4}
My configuration.yaml has the following…
sensor 2:
platform: mqtt
name: "Office Lux"
state_topic: "/merakimv/<camera SN?/light"
unit_of_measurement: "lux"
value_template: '{{ value_json.lux[0].value }}'
qos: 0
Could someone point me in the right direction or provide some assistance?
Thanks
