Thank you for your feedback — we really appreciate you bringing this to our attention.
We’ve looked into this issue and found that some Matter-over-Thread devices, including the T2 bulb, may occasionally fail to be added to the Aqara Home app via iOS devices. This appears to be related to changes introduced in iOS 18.4, as the issue does not occur on iOS 18.3 or earlier. We’ve already reported this to Apple and are actively working with them to find a solution.
In the meantime, we recommend using the Aqara Home app to add your T2 bulb and selecting the ”Zigbee Mode“ during setup. This can help avoid the current Thread pairing issue, and the ”Zigbee Mode“ also supports more features compared to the Matter-over-Thread version.
We understand how frustrating this must be, especially since you’ve successfully added similar devices before. Please rest assured that this issue is not specific to your devices — it affects certain combinations of iOS 18.4+ and Matter-over-Thread pairing, and we are doing our best to get it resolved as quickly as possible.
Thanks again for your patience and continued support!
