Hello, help please.
Here’s is my blueprint to calibrate Tado offsets, based on an external zigbee sensor.
blueprint:
name: Update Entity Offset
description: Update the offset attribute of an entity based on another sensor's state
domain: automation
input:
sensor_to_monitor:
name: Zigbee Sensor to Monitor
description: The sensor whose state will be used to update the "offset" attribute
selector:
entity:
domain: sensor
device_class: temperature
entity_to_update:
name: Tado Entity to Update
description: The entity whose "offset" attribute will be updated
selector:
entity:
domain: climate
threshold:
name: Threshold
description: The maximum difference between the two sensors to trigger the automation
selector:
number:
min: 0
max: 10
step: 0.5
unit_of_measurement: "°C"
trigger:
platform: numeric_state
entity_id:
- !input 'sensor_to_monitor'
- !input 'entity_to_update'
value_template: "{{ (states('sensor_to_monitor')|float - state_attr('entity_to_update', 'current_temperature')|float)|abs }}"
above: !input 'threshold'
action:
- service: tado.set_climate_temperature_offset
data:
offset: "{{( state_attr('entity_to_update', 'offset_celsius')|float if state_attr('entity_to_update', 'offset_celsius') is not none else 0 ) + ((states('sensor_to_monitor')|float - state_attr('entity_to_update', 'current_temperature')|float) if states('sensor_to_monitor') is not none and state_attr('entity_to_update', 'current_temperature') is not none else 0 ) | round(1)}}"
target:
entity_id: !input 'entity_to_update'
All looks fine but the offset value that should be calulated in the action, just doesn’t get values from the entity and the sensor… It looks like input variables aren’t rewritten with the actual name of the entity/sensor I choose from the automation.

It is an input, not a variable.
You need a variables block to access it like that.

Wow, that worked but only if I run the automation manually. It ignores the threshold of 0.5°C I set in the automation. There must be something not working within the trigger section. I know you would probably know but the value_template is an absolute number so either the difference is positive or negative the threshold should trigger the automation anyway.
It basically gets the difference between the two sensors, and if the difference is higher than the threshold set it triggers the automation. The value is all wrapped up with an absolute parameter so whether is -0.5 or 0.5 the value is always 0.5. Despite setting a 0.5 value and forcing one of the two sensor’s value to a higher number so the difference is >0.5, the automation won’t run.
If I change the variables with entity/sensor names in the dev tools I get the correct value. It seems like the expression isn’t set in the right way so variables are replaced with real entity/sensor names.
Replacing by hand the names of the entity/sensor I get a correct value:
I still had to use quotes around the entyty/sensor otherwise I couldn’t get any result. I am wondering if something like what you suggested for the action part has to be done also for the trigger part.
