I have an automation that should activate a change in thermostat setting if one of my TRVs needs heat, but I’m getting some errors in the log I cannot figure out.
This is my automation:
alias: Study Ask Heat
description: ""
trigger:
- platform: template
value_template: |-
{% set therm = states['climate.big_study_radiator'] %}
{{ therm.attributes.current_temperature < therm.attributes.temperature }}
- platform: template
value_template: |-
{% set therm = states['climate.small_study_radiator'] %}
{{ therm.attributes.current_temperature < therm.attributes.temperature }}
condition:
- condition: template
value_template: |-
{% set therm = states['climate.incomfort_1'] %}
{{ therm.attributes.current_temperature > therm.attributes.temperature }}
action:
- device_id: 90ed87e3fcc7dbd52e4ad12748189c45
domain: mobile_app
type: notify
message: Living Room 19
- service: climate.set_temperature
data:
temperature: 19
target:
entity_id: climate.incomfort_1
mode: single
And here’s the error code:
