Home Assistant script to set an entity's state, used with the IKEA Tradfri remote control.

set_state.py

if 'entity_id' not in data:
  logger.warning("===== entity_id is required if you want to set something.")
else:
  data = data.copy()
  inputEntity = data.pop('entity_id')
  inputStateObject = hass.states.get(inputEntity)
  if inputStateObject:
    inputState = inputStateObject.state
    inputAttributesObject = inputStateObject.attributes.copy()
  else:
    inputState = 'unknown'
    inputAttributesObject = {}
  if 'state' in data:
    inputState = data.pop('state')
  logger.debug("===== new attrs: {}".format(data))
  inputAttributesObject.update(data)

  hass.states.set(inputEntity, inputState, inputAttributesObject)

My entity is create by broadlink RF. Got Switch,Fan. It should be an offilne entity.
Previously this entity just send RF code to control switch or Fan.
The reason I use this python script, I built an RF receiver so that when I use original remote controle to send RF code I can use my RF receiver to receive the code and set the correct state for the entity.

Interesting use case. If you set the state in HA under the Development panel does it revert? Testing that would either confirm it's the python script or rule it out. Also does the Log book or logs show anything?

Yes. I have tested under dev tool. It behave same.
And just checked logs, no any logs shows about this.
Current log level set to debug.
Please advise how should I troubleshoot this.
