Homey self hosted - Aqara T1M ceiling light - unable to add

Questions & Help

Hi

I been using first the 2019 pro then the 2023 pro but decided go HAOS.

Both in 2023 pro, Aqara M3 hub and HAOS i had no issues adding my Aqara light.

It shows the guide, starts adding, then shorty after it comes up "(translating from norwegian) cant connect to. Something went wrong when the device was to be added, try again. If battery powered, try pushing the connection button to keep active.

Everything else zigbee seems to working, termostats etc adds fine, also Aqara lightstrip.

If i try adding them back to homeassistant or Aqara hub they get added.

Anyone got any idea whats wrong?. When adding to Aqara hub i try look for new firmwareupdates, but they are updated.

Using homey bridge (also updated).

Bought lifetime for HSH.

Not much life on these forums. Maybe best stick with HAOS :smiling_face:

How many routers (mains powered Zigbee devices) and end devices do you have? Homey only supports up to 15 directly connected devices, the other devices need to be connected through a router.

Also, did you follow the Zigbee best practices guide? In short: connect your routers first during setup, and then connect end devices afterwards.

“HAOS”? Is that another Zigbee gateway? Note that you can only connect the device to 1 Zigbee network at a time

HAOS is Home Assistant Operating System.

Similar issue with Aqara T1M here.

Existing Aqara T1M paired earlier still works on Homey Pro 2023.
Same model T1M, reset and updated via Aqara M3, can be added to Aqara M3, but cannot be added directly to Homey Pro 2023 or Homey Pro 2026.
Homey finds the device, but fails at final inclusion with “Something went wrong”.
This suggests a regression in T1M pairing support.

For the new T1M light, does any of these descriptions match in any way?

I am unable to pair an Aqara Ceiling Light T1M (Zigbee 3.0 version, model CL-L02D [verify on box], LED driver ATD-40WHC) to my Homey Pro (2026).

Setup:

  • Homey Pro (2026), firmware [version]
  • Aqara & Xiaomi Smart Home app, version [version]
  • Light firmware: [version, if known]
  • Distance to Homey during pairing: [x m]

Steps:

  1. Factory reset of the light (power-cycle sequence per Aqara manual).
  2. Add device → Aqara app → Ceiling Light T1M.
  3. Homey starts pairing, then shows: “Unable to connect – Something went wrong while adding this device, please try again.”

Already tried:

  • Repeated resets and pairing attempts
  • Restarting Homey
  • Pairing close to Homey
  • [Pairing as an unknown Zigbee device – result]

Other Zigbee devices pair and work normally. Several users on the Homey Community Forum report the same issue with T1M on Homey Pro 2023 and 2026 since spring 2026: the device is found but final inclusion fails, while previously paired T1M units keep working. This looks like a regression in T1M pairing support.

Could you please check the logs from my latest pairing attempt?

Thank you,

The challenge (problem) is that pairing of Zigbee devices is handled by the Zigbee core, until a match towards an app and driver is found. An apps diagnostics report therefore does not show any logging of the pairing process (sandboxed).

You trigger me here… So the end result is that the pairing of the device is succesfull, but the device is added as an unknown Zigbee device?

If so, it looks like that Homey core is not able to find the correct app-driver match. Can you share the manufacturer ID and product ID of the unknown Zigbee device as shown in it’s advanced device settings?
