Pass temperature to sensor

[charred sorrel]

Hi everyone,
I am trying to pass a value from a webhook to a sensor (helper template with °C as unit). Everything seems to work fine except passing the value to the sensor.

I am using the GUI for automations and using the following YAML for passing the value:

action: number.set_value data: value: "{{trigger.json.temperature}}" target: entity_id: sensor.living_temperatur

Unfortunately, the trace of the automation shows the following, including an error:
Error: expected float for dictionary value @ data['value'] Result: params: domain: number service: set_value service_data: value: 23,2 °C entity_id: - sensor.living_temperatur target: entity_id: - sensor.living_temperatur running_script: false

I am not really sure how to fix this but I suspect the error occurs from the transmitted value containing " °C"?

Thanks for helping me out 😄

You could just pass the value and strip out the units:

data:
  value: "{{trigger.json.temperature | select('in', '1234567890.,') | join }}"

The comma as decimal seperator will also cause issues

data:
  value: "{{trigger.json.temperature | select('in', '1234567890,') | join | replace(',', '.') }}"

Thank you guys, this fixed the error. You are amazing!

May I ask you what the "select" function is doing and what parameters it is taking?

The select function is defined here: https://jinja.palletsprojects.com/en/stable/templates/#jinja-filters.select

The quick explanation for this application: it takes the string supplied to it and outputs a list of only the characters that are in (1st argument) the 2nd argument (1234567890,). The join filter then combines that list back into a single string.
