Ikea Parasoll sensors (via Matter Bridge) not triggering flows after recent update

Hi,

I’m using several Ikea Parasoll sensors in my home. I originally had them connected directly to my Homey Pro (2023), but since they were draining batteries very quickly (some of them died within a week), I switched to using the Ikea Gateway, which I connected to Homey Pro as a Matter Bridge.

Since the latest Homey update (I’m not entirely sure if it started with version 12.7.0), I’ve been experiencing an issue where activity on these sensors no longer triggers my flows.

In the attached flows, I’m using the trigger “when a zone becomes active”. This should also work with door sensors — and I can actually see on the device status in Homey Pro that the sensor registers the activity. However, the flow doesn’t start.

In Flow 1, it only triggers if I manually turn on the light via an Ikea switch (also connected directly to Homey Pro).

In Flow 2, the flow only triggers when a Philips Hue motion sensor (connected directly to Homey Pro) detects movement.

I have both Ikea Parasoll door sensors and Valhorn motion sensors added via the Ikea Gateway. Interestingly, the Valhorn motion sensors seem to work fine — they trigger flows with the same configuration — but the Parasoll door sensors do not, even though I can see their activity updates in Homey.

Thanks a lot for your help with this.

Best regards,
Jirka

Do they actually activate the zone they’re in?
There’s a device setting to enable zone activity.

Did you cut the power to Homey for 10 minutes already?
This is known to solve the weirdest occurring issues after a firmware update.
