Hi everyone,
The new IKEA MYGGBETT door/window sensor is officially marketed as a Matter-over-Thread device. However, I’ve been researching online and found several reports suggesting that newer IKEA Matter products (like the Kajplats bulbs and Bilresa button) might have “hidden” Zigbee compatibility.
Since IKEA often uses similar chipsets across their range, there is a theory that the MYGGBETT might still have a Zigbee stack that can be manually triggered. I’ve compiled a few methods found across the web and would love for people with a Zigbee sniffer (Z2M/ZHA) to test these out.
Methods to test for Zigbee pairing:
-
The “4-Click” Standard Reset:
-
Press the pairing button 4 times rapidly within 5 seconds.
-
Observation: The LED should pulse orange/red. While this is the official Matter pairing mode, check if your Zigbee coordinator picks up any signal.
-
-
The “12-Click” Hard Reset (Successful on Kajplats bulbs):
-
On some newer IKEA Matter hardware, pressing the button (or power cycling) 12 to 15 times has been known to force a fallback to Zigbee.
-
Action: Rapidly tap the pairing button 12 times and see if the LED pattern changes.
-
-
The “Long Hold + Multi-tap” Sequence:
-
Hold the pairing button until the LED flashes red.
-
Release and immediately tap the button 4 times.
-
Wait 2 seconds, then tap another 8 times.
-
(This specific sequence has been used on other dual-protocol IKEA remotes).
-
-
Battery Induction Reset:
- Hold the pairing button while inserting the battery. Continue holding for 10 seconds until the LED stops flashing, then release.
Why test this?
If we can confirm a Zigbee fallback, this sensor becomes much more versatile for those without a Thread Border Router. However, there is a possibility that IKEA stripped Zigbee entirely from battery-powered sensors (like MYGGBETT and the Badring water leak sensor) to save power.
Please let me know if you manage to get a “Join Request” in your Zigbee logs! Any feedback or logs from ZHA/Zigbee2MQTT would be greatly appreciated.
