Hi, I’m trying this automation:
trigger:
platform: numeric_state
entity_id: sensor.living_room_t_set_cal
above: 1
action:
service: mqtt.publish
data:
topic: "sensor/heating/living_room/master_msg"
payload_template: '{"type": "Tset", "value": states(\'sensor.living_room_t_set_cal\')}'
#"{\"type\": \"Tset\", \"value\": {{ sensor.living_room_t_set_cal }} }"
however, I’m failing to create the payload_template
containing the value
of the sensor inside of the json payload.
any hints?

Change:
data:
to:
data_template:
I’m not 100% certain it will fix everything … but it’s a start.
NOTE:
I’ve never seen this format before:
payload_template:
type: "Tset"
value: "{{ states.sensor.living_room_t_set_cal }}"
It’s not described in the documentation . Where did you learn how to define the payload this way? I’d like to learn more about it.

Sorry @123 , I just noticed your edit. I did a major edit of my original post, as I found several errors and fixed them. Now I’m just having 1 error. Will try your solution. regarding the nested payload_template, well, that was just me being inventive. it makes kind of sense, no?

It does make sense but, as you’ve discovered, it’s invalid.
Try this:
- alias: 'example 1'
trigger:
platform: numeric_state
entity_id: sensor.living_room_t_set_cal
above: 1
action:
service: mqtt.publish
data_template:
topic: "sensor/heating/living_room/master_msg"
payload: >
{{'{{"type": "Tset", "value": {}}}'.format(trigger.to_state.state)}}
I tested a slightly different version of it on my system and it successfully published payloads like this:
{"type": "Tset", "value": 19.0}
