Help Needed: VALLHORN Motion Sensor and TRÅDFRI Light Setup Issue ZIGBEE

Configuration Zigbee
1

Hi everyone
I’m new to Home Assistant and recently purchased the VALLHORN motion sensor and a TRÅDFRI light from IKEA. I set them up in my closet with the goal of having the light turn on when the door is opened (or motion is detected) and turn off when the door is closed (or no motion is detected).

Here are the settings I configured, but for some reason, it’s not working as expected. Any advice or suggestions would be greatly appreciated!

You should also (and foremost) post the automation you created (as text, please, not screenshots)

A few thoughts: use the “occupancy” state not the “opened” state and instead of targeting the area, target just the entity you want to turn on. Also, you can test if the light turns on by manually running the automation and you can see if the trigger works in the automation editor as well.

Another two things to consider: you can use the motion activated light blueprint (click new automation then choose “motion activated light”) and motion sensors take 15-60s to reset after each motion, so they can be a bit difficult to test.

Define “not working as expected”.

I have vague memories of having to manually reassign the types of one or more binary sensors because they were not correct in the default quirk. As long as you use the correct entity that shouldn’t really matter though as it just changes what the states are called. One of entities will immediately deactivate when it no longer detects motion, while the other has a 1 or 5 minute delay, set by one of the buttons on the back.
