Motion activated lights automation

This gets asked a lot so here is an example for automating a light to come on with movement and go off after there is no movement for a short time.

  - platform: state
    entity_id: binary_sensor.your_motion_sensor_here # change this
    to: 'on'
  - platform: state
    entity_id: binary_sensor.your_motion_sensor_here # change this
    to: 'off'
      minutes: 2 # adjust as necessary 
  - service: "light.turn_{{ trigger.to_state.state }}"
      entity_id: light.your_light_here # change this
mode: single

Hehe…you should pin this one :face_holding_back_tears:

For the Node-Red folks:

I prefer this one for NodeRed :grin:

This is great, thanks for providing it @tom_l.

I’d like to have a group of 3 lights pulse on/off for say 1 minute after motion is detected. Is there a way to achieve this using your example?

Start another topic. It’s beyond scope for this one.

Since not all motion sensor return to an ‘off’ state, you might end up with using a delay.
In that case, you need to put the automation in restart mode, so it will reset the delay when re-triggered.
f.e. my mqtt motion detector:

alias: Hallway Downstairs Light on Motion
description: Off when no motion for 3 mins
  - alias: When motion detected hallway downstairs Pir] was trigged by MQTT
    platform: mqtt
    topic: Tasmota/tele/RESULT
    payload: D4A0EF
    value_template: '{{ value_json.RfReceived.Data}}'
condition: []
  - service: light.turn_on
      entity_id: light.hallway_downstairs
  - delay:
      hours: 0
      minutes: 3
      seconds: 0
      milliseconds: 0
  - service: light.turn_off
    data: {}
      entity_id: light.hallway_downstairs
mode: restart
