I wanted to check if anyone is successfully using SLZB-06 with Aqara bulbs (T2-E27).
Previously, I was using a Sonoff Zigbee 3.0 USB Dongle and all my Aqara bulbs were working perfectly (on/off, brightness, etc.). Recently, I migrated my Zigbee network to an SLZB-06 coordinator and since then the Aqara bulbs have stopped working.
Current behavior
Bulbs are discovered successfully
Devices appear online in Zigbee2MQTT
State/brightness commands timeout
Bulbs do not respond to any control commands

Any confirmation, workarounds, or recommendations would be greatly appreciated.
The error about the missing manuspecificlumi cluster & the failed to configure error say otherwise.
Hit Reconfigure for those bulbs & check whether the missing cluster shows up & configuration completes successfully.
Otherwise try deleting & pairing them again via a closer router.
I have pressed reconfigure button didn’t help. I have deleted them and added them multiple times. They get discovered within 2-3 seconds the whole interview process takes place where there is a wheel icon rotating next to bulb icon. Once that is complete the issue remains same. Doesn’t change any state or anything.
I replaced controller back to Sonoff and the bulbs after repairing started working again.
Bear in mind that I don’t own the T2 bulbs, so the advice below is simply based on google searches:
Did some digging around in the Z2M Github and someone mentioned that the bulbs establish a binding to the coordinator.
I have a feeling that’s what you’re seeing - the bulbs are still bound to your Sonoff, which is why they work with the Sonoff but not the SZLB-06.
You should be able to confirm this by opening the bulb device page in Z2M & clicking the Bind tab. If you’re still using the Sonoff, you should see something like this:
I think the cleanest way to get them to pair with the SZLB-06 is to reset the bulb itself so that it gets disconnected from your coordinator. Note that this might cause the bulb to switch back to Matter mode according to the instructions, so try it with a single bulb first:
Alternatively, take note of the current bindings, unbind the device from the Sonoff, force delete the device, restart Z2M then try to pair it to the SZLB-06. I would only do this as a last resort though, since the bulb might still think it’s bound to the old coordinator if you don’t reset it.
