Transfer value from one entity to another

Configuration
1

Thought this would be rather simple, but have not managed to find out how. Would like to take a value from one entity (eg weight registered in garmin) and transfer that value to another entity (eg color temp for a hue bulb). Tried to get a value from an entity into an input number and then from the input number into another entity, but without success.

Any guidance would be much appreciated

Create a template sensor

To use it to set another existing entity you would need to call the appropriate service call to do that. Aka, just make an automation! :smiley:

thanks, and sorry for my ignorance, but thought I could do something like this

service: input_number.set_value
data:
value: ‘{{ sensor.weight }}’
target:
entity_id: input_number.weightnow

… but does not work

You can, if you get the syntax right. Here’s my max power recorder automation that copies the power sensor value to an input_number for long-term storage:

- alias: Energy - max power recorder

  description: Updates the maximum power recorder whenever prior maximum is exceeded

  id: 1fef4933-5115-4055-91d2-48d5d3a051b7

  trigger:
    - platform: template
      value_template: "{{ (states('sensor.power_meter_house')|float > states('input_number.max_power')|float) }}"

  action:
    - service: input_number.set_value
      data:
        entity_id: input_number.max_power
        value: "{{ states('sensor.power_meter_house')|float }}"

You cold also use '{{trigger.to_state.state}}'

service: input_text.set_value
target:
  entity_id: input_text.input_text_test
data:
  value: '{{trigger.to_state.state}}'

thanks, worked

Just adding my latest addition (new to HA).
If you have multiple sensors and heaters and if you can keep the naming, you only have to add the temperature sensors under entity_id.
My sensors are always named room-name temperature and my heaters are always named room-name heater.
Hope it helps!

alias: Sync Room Temperatures to Heaters
description: Automatically sync temperature sensors to heater numbers
triggers:
  - entity_id:
      - sensor.livingroom_temperature_temperature
    trigger: state
conditions:
  - condition: template
    value_template: >
      {{ trigger.to_state.state | float(0) != trigger.from_state.state |
      float(0) }}
actions:
  - target:
      entity_id: >
        {% set room =
        trigger.entity_id.split('.')[1].replace('_temperature_temperature','')
        %} number.{{ room }}_heater_external_temperature_sensor_value
    data:
      value: "{{ states(trigger.entity_id) | float(0) }}"
    action: number.set_value
mode: parallel
