Move entity 1 to entity 2

Hello all,

I can’t find the answer on google or in the forum because I don’t know a good searching term.
But is it possible to move a entity to anoter entity? I read the room temperature with a zigbee device and I want that room temperature to another entity. It is possible in HA to set a fixed value to an entity but I don’t want a fixed value.

Do you mean you want to add that entity to another existing device?

If so, no that is not possible.

You can group together whatever entities you want in an entities card though.

Yes that’s what I want, but unfortunately that is not possible.

It is also not possible to make HA an ModBus slave device?

I don’t think so, but I don’t use modbus.

I found in another topic the solution.

That is completely unrelated to the question you asked?

Maybe I didn’t ask the question quite right. But in this case;

alias: tv02 automation
description: ""
trigger:
  - platform: state
    entity_id:
      - input_number.tv02
condition: []
action:
  - service: number.set_value
    data:
      value: "{{ states('input_number.tv02') | float(0) }}"
    target:
      entity_id: number.thermostat_wz_boost_timeset_countdown
mode: single

The “input_number.tv02” moves to the “number.thermostat_wz_boost_timeset_countdown”. That’s exactly what I want. Entity 1 to entity 2. And for my case I changed the “input_number.tv02” to the room temperature sensor.

Yeah that’s not adding an entity to a device. That is setting the value of one entity to another.
