How do I get hass.io to publish DarkSky humidity to Mosquitto

[Elway (Morten de Melo Lyng)]

2 weeks in with hass.io - waiting for a bunch of Sonoffs and trying to figure “it all” out.

So - I got Mosquitto up and running on the same Pi as Hass.io is on. I tested it with MQTT.fx - so far so good.

Now, I set up DarkSky also, and I get DarkSky data in.

But how to I set up Hass.io to publish DarkSky humidity to MQTT? at given time intervals or whenever the state/value changes

I found someone talking about a Service called mqtt.publish, but I cannot find it under Services… lost…

Take a look here:

Automation: Reading an attribute and publishing it to MQTT

This works to send relay state 0/1 to mqtt - id: relay1_state_to_mqtt alias: Relay1_State_ToMqtt initial_state: 'on' trigger: - platform: state entity_id: switch.qubino_zmnhadx_flush_1_relay_switch action: - service: mqtt.publish data: topic: "service/hasszw1/device/relay_1/state" payload_template: '{% if is_state("switch.qubino_zmnhadx_flush_1_relay_switch","on") %}1{% else %}0{% endif %}' retain: true but this ALWAYS publishes 1 - id: rela…

Thanks VDRainer - will do.

I took another route - got it done in the Node-Red add-on for Hass.io - with some help from the Node-Red Slack community

Seeing as I pretty much did this last night (albeit with a different sensor), I thought I might as well put it on here for others anyway

Create an automation as follows, and everytime the state of the sensor (the value in this case) changes, it will trigger and publish to the MQTT topic:

- alias: 'bathroom humidity'
  trigger:
    platform: state
    entity_id: sensor.bathroom_humidity
  action:
    service: mqtt.publish
    data_template:
      topic: 'homeassistant/sensor/bathroom/humidity'
      payload_template: '{{states.sensor.bathroom_humidity.state}}'

You’ll have to change the entity_id for the trigger, to that of the Darksky humidity sensor, then set the topic in the action to whatever topic you wish to publish to. Lastly, change the payload_template to match the Darksky humidity sensor.

I’m using the above to push the humidity reading from one Home Assistant install, to another via MQTT. That way I have have a “live” system and a development system using the same sensor names and values.
