Correct me if I’m wrong, but…
Buyer Beware! Aqara hubs use the Zigbee protocol, but lock out 3rd party devices!
A few months ago, I bought an Aqara hub and went deep into their ecosystem. I saw their hub and sensors had good reviews, plus they were using the Zigbee open protocol, so I figured I’d stick with their stuff. I had no reason to try other devices until recently.
I picked up a tilt sensor for my garage door from a 3rd party. I made sure it was also using the Zigbee protocol, so I assumed it would be compatable. Unfortunately, when I tried connecting it to the hub, I was wrong and it wouldn’t connect. Turns out, Aqara uses the Zigbee protocol, but locks out 3rd party devices. [source]
If anyone has a workaround to integrate a 3rd party device with an Aqara Hub (IIRC, I have the M3?), I’d love to hear about it. But until then - I’m looking for a refund. I would have never picked up their hub if I had known about their shennanigans; and consequently, I wouldn’t have picked up so many of their sensors.


This is pretty normal. Philips also uses ZigBee for Hue and you can’t connect non-Philips ZigBee devices to it. This is the major reason I started using Home Assistant. I use Home Assistant Yellow which has a built-in ZigBee radio but ZigBee radios can be added via USB to any setup running Home Assistant. ZBT-2 is pretty great for high performance unit. Sonoff have a cheaper dongle.
I’ve got the Sonoff dongle and it works pretty well. I’ve got lights from ThirdReality and sensors from Aqara, ThirdReality, and Sonoff. Everything works seamlessly in Home Assistant
Speaking of devices, I’m actually still using an ancient Conbee II and it’s rock solid. I thought about changing it recently and ordered a ZBT-2 for a more up to date product, but then I realised I was insane and set it up as a Thread Border Router instead, so I have both now.
I just got ZBT-2 for my first Matter/Thread device and hooked it up to my HA Yellow. This thing now does ZigBee, Thread and Z-Wave. 😆
Nabu Casa’s own documentation says the ZBT-2 does NOT support multi-protocols. The zbt-2 does work with Matter, but then won’t support Zigbee.

“Connect ZBT-2 cannot do both Zigbee and Thread simultaneously. This technology is often called “multiprotocol” or “MultiPAN”. Though it is theoretically possible with the hardware within Connect ZBT-2, in our experience, this functionality doesn’t work well, and we don’t plan to implement it. We previously thoroughly tested multiprotocol with our Connect ZBT-1 adapter and found its operation to be inconsistent, often causing device stability issues. We do not believe multiprotocol is suitable for operation in the home, and strongly recommend dedicating a device to each protocol.”
I didn’t mean to imply it does. I use the built-in ZigBee radio on the HA Yellow. The ZBT-2 is only doing Matter/Thread. I also got a Z-Wave radio hooked to the Yellow’s GPIO.
Fair enough. I just didn’t want others who read your post to be misinformed.
Winning at protocol mastery. I commend thee.
