Ikea tradfri motion sensor turn on lights living room

Hi people,

I am trying to make my tradfri motion sensor let to go the light in the living room on when motion is detected.
But in my place it doesn’t do nothing at all.

  • id: ‘1542726560916’
    alias: Lights livings room turn on when motion detected
    • entity_id: sensor.tradfri_motion_sensor
      from: ‘off’
      platform: state
      to: ‘on’
      condition: []
    • data:
      entity_id: light.tradfri_bulb_e27_w_opal_1000lm_2
      service: light.turn_on

Can someone help me?
When you need more information from me, let me know.


Unfortunately it isn’t working that way. HA can only retrieve the battery status from the motion sensor and not the sensor state itself. You have to group the bulb and the sensor with the Tradfri app so the light can switch on when the sensor senses motion.
You can do it indirectly. Buy another Tradfri bulb and group that one with the motion sensor. Turning on that bulb will trigger th other one by HA.

Allright clear.
Is there any other way to make it work or is it just not possible?
Are there other motion sensors where HA can get the trigger from? Or is it allways this way?

I hope Ikea will change their firmware some day so it becomes possible to read the sensor state. Every other compatible motion sensor should work. I did not try the myself.
I think the Tradfri sensor is not very good at all. To save energy it checks for motion every 5 seconds or so. That’s too slow for many purposes.
