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)

If you're actually using this for a tradfri remote, note that it's not been necessary for a long time - zigbee2mqtt improved their support for the device and it just works out of the box. If you're using it to do other state manipulations... carry on :)

I can't believe this doesn't have more stars, perfect! Works for switches just as well.

Just saved my day mate! Very odd that HA doesn't have this as a built-in action type...

My thoughts exactly. Very odd in deed.

Well, actually my original thought was more along the lines of "WTF? Why is this even necessary? Why isn't this built-in?". But I like yours better, for it's way more polite.

Hello,

When i set this in my automation :

  - service: python_script.set_state
    data:
      entity_id: sensor.energy_spent
      state: ''

I got this error : "Message malformed: expected dictionary @ data['action'][0]"

Do you have an idea on what is happening ?

Are you sure "sensor.energy_spent" holds a state? It looks more like a value type to me.

yes you're right it s a value type, but when I m using set state from developer tools, setting state to 0, it clear the value, I was thinking that this script will do the same...

sorry it works when I do it like this :

service: python_script.set_state
data:
  entity_id: sensor.energy_spent
  state: '0'

thanks for your help !

State reverse back 5 seconds after set_state when running latest HA.

Is this happening with an entity that was previously holding its state for a long time after being set with this python script? It might depend on the entity you're setting the state of. Some update very frequently. I've set states in the Developer panel before and they updated and override my change within a very short period.

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.

Yes. I have tested under dev tool. It behave same.

I.e If you set the state in Dev Tools it reverts automatically? In this case, nothing can be done to override the constant and continual state updating that HA/componets inherently do.
