MQTT Dash Commands (json) to Jinja2

I am having a hard time inputting my sauna controller json commands into HA. Any easier way to do this?

Have you got some examples of the mqtt published.

This is the info published to sonoff/sauna:
“celcius”: 19,
“fahrenheit”: 66.2,
“state”: 0,
“active”: 0,
“setpoint”: 100,
“autooff”: 0

And this is the message published by sonoff/sauna/set:
“state”: true

Power ($.state), Active ($.active), Temp Celcius ($.celcius), Temp Fahrenheit ($.fahrenheit), and AutoOff ($.autooff) all subscribe to sonoff/sauna and extract from JSON path with $.value format (i.e. $.value).

Power and Active are set as buttons on MQTT Dash with ‘enablepub’: ‘false’. Temps and AutoOff are text tiles with ‘enablepub’: ‘false’.

SetPoint is a multi-choice tile with options ranging from 60 to 110 (degrees F) in format ({“setpoint”:65}) labeled 65. SetPoint is subscribed to sonoff/sauna and publishes to sonoff/sauna/ set.

I have gotten the On/Off button, Temp fahrenheit and AutoOff to work by inserting this into yaml:

  • platform: mqtt
    unique_id: sauna_switch
    name: “On/Off”
    command_topic: “sonoff/sauna/set”
    payload_on: ‘{“state”: true}’
    payload_off: ‘{“state”: false}’
    state_on: ‘{“state”: true}’
    state_off: ‘{“state”: false}’
    optimistic: false
    qos: 0
    retain: false


  • platform: mqtt
    unique_id: sauna_temp_f
    name: ‘Fahrenheit’
    state_topic: ‘sonoff/sauna’
    qos: 0
    value_template: ‘{{value_json.fahrenheit}}’
    unit_of_measurement: ‘°F’

  • platform: mqtt
    unique_id: sauna_autooff
    name: ‘AutoOff’
    state_topic: ‘sonoff/sauna’
    qos: 0
    value_template: ‘{{value_json.autooff}}’
    unit_of_measurement: ‘m’’

Stangely, Celsius ‘{{value_json.celciust}}’ outputs Fahrenheit value with " unit_of_measurement: ‘°F’ ", and Active/Power:


  • platform: mqtt
    unique_id: sauna_power
    name: “Power”
    state_topic: ‘sonoff/sauna’
    command_topic: “sonoff/sauna”
    payload_on: ‘ON’
    payload_off: ‘OFF’
    state_on: ‘ON’
    state_off: ‘OFF’
    qos: 0
    retain: true
    value_template: ‘{{value_json.state}}’’

Does not update when ‘On/Off’ changes state (I figure it has to do with the ‘command_topic’ HA requires for ‘switch’ since it has no ‘enablepub’ option.
