I got a new zigbee thermostat that's able to take the temperature of an external thermometer as the local temp. I want to have home assistant set this value on my thermostat when the thermometer changes.
I'm a bit confused on how I can set the thermometer to the thermostat. The text box shown only allows numerical input so I can't put a variable name (I would imagine it's sensor.bedroom_temp_temperature?)
Let me know if I'm approaching this incorrectly.
Thanks

A couple things: first, you can’t use templates in device actions. You’d need to delete that action, and add a new one. In the “add action” dropdown, the first option is “device, a great was to start”. It’s actually a horrible way to start. Scroll down further and select “climate”
But, it looks like the automation you are setting up is going to set the target temp of the thermostat to whatever your Zigbee thermometer measures. Is that really what you want to do?
If your Zigbee thermostat can use an external Zigbee temp sensor, that might be by pairing the external sensor to the thermostat directly

If your Zigbee thermostat can use an external Zigbee temp sensor, that might be ...
Yeah this is what I realized, it's supposed to be for a wired external sensor, and that Temperature attribute i was trying to set isn't actually set point, its calibration
I have a new idea now though, can I set the calibration to the external - internal?
That way, the thermostat is thinking it's the temperature at my probe

Makes sense to me

So how would I go about doing that? If i use a climate object, can't I only change the set point?

Depends on the device and the integration. Probably need to send a Zigbee configuration parameter

Its this one, the id is number.bedroom_thermo_local_temperature_calibration

Stuff in curly braces are called templates. That’s what you’ll need to put in the “value” area in my screenshot

Does this look right?
service: number.set_value
metadata: {}
data:
value: >-
{{ sensor.bedroom_temp_temperature -
state_attr('climate.netatmo_master_bedroom', 'current_temperature') }}
target:
device_id: db2ea25eec51a974afc2eef31bed944d
entity_id: number.bedroom_thermo_local_temperature_calibration
wait forgot to change the thermostat name lol

You need the states() function to get the state of your temp sensor, and you have to convert it from a string to a float because all states are strings.
You can prove a default value to the float filter to handle cases when the external temp sensor is unavailable. It will just error out without a default. For example
… | float(20) …
I’d recommend putting the template into developer tools -> templates to try it out first

Thank you

Also, you just need the entity ID as the target. You don’t need the device. If you use the device, it will change every number entity that the device has.

I think i got it working now
Thanks for your help
