IKEA BILRESA events firing twice

Configuration Matter/Thread
1

I setup two BILRESA remotes today through Matter over Thread with a ZBT-2 as the router, everything works fine except that quite frequently the state machine will show two duplicate events back to back when the remote was only pressed once, this happens on both buttons and all the different types of presses, single, double, long and long-release.

This can lead to problems for example when a press action performs a toggle action on an entity which leads to the automation toggling the entity twice back to its original state.

I’m not sure if the issue is with the button itself sending two events or if the issue is somewhere else down the line. I doubt that it’s with the button itself as the events can reliably be detected and debounced as the state updates in the state machine are consistently ~0.15ms of each other/less than 1ms between the duplicate events.

Has anyone else seen this issue with the IKEA BILRESA remotes or other Matter remotes?

The best way I know to test this is to create an automation which triggers on the remote events and sending a persistent notification or performing some other visible action if the following condition is met

{{(trigger.to_state.last_changed - trigger.from_state.last_changed) > timedelta(seconds = 0.001)}}

I have the same issue with IKEA Bilresa, using a SLZB-MR3, duplicate events

What kind of batteries have you put in? I think those devices work best with Nmh rechargeables. I have had strange results myself when using Alkaline.

I’ve only used genuine Eneloops in the IKEA products, specificially the BK-4MCDA 800 mAh AAA batteries

Sharing what I have come across:

  • This Forum user sees the same and captured the two events on the Event Bus.

  • I myself am only seeing one event on the Event Bus for single press. Note: For long press I am seeing long press and when released I see long release. For comparison I am running 2026.1.1 and the following is what is shown on the Device page:

for me restarting the Matter integration solved the issue

I need to investigate further, but it seems that I can no longer replicate the issue so it’s possible that restarting HA resolves the issue. I’ve got some new unpaired Bilresa remotes so I’ll try at some point with those.

Did not try the reboot yet and the issue persists on 2025.12.5. Can I help debugging this by exporting logs or so? Would be happy to help but need instructions :wink:

I would restart Matter integration and see if it’s gone.
