[Compatibility Features] With an Aqara Zigbee 3.0 hub (Excluding the Camera Hub G2H), the Dual Relay Module T2 is compatible with a variety of mainstream ecosystems, like Matter (A Matter compatible Aqara hub is required), Apple HomeKit, Alexa, IFTTT, and the Aqara Home app. This broad compatibility allows for easy integration into diverse smart home setups and usage in smart home automation.
[Dry Contact Mode] The Aqara Dual Relay Module T2 supports dry (or potential-free) contact mode with both pulse and on-off switching, allowing for the integration of a wide variety of electrical devices such as boilers, garage doors, and more into your smart home setup.
[Wireless Switch Mode & Motor Control Interlock] The T2 provides easy and secure control of tubular motors and can also function as a roller shade switch. Utilizing the Wireless Switch Mode, the T2 can convert an existing wall switch into a scene controller without requiring any wiring changes. For instance, a button can be assigned to arm your wired doorbell or security system, enabling the integration of other wired sensors into your smart automations (AC only).
[Energy Saving & Power-off Memory] With advanced energy monitoring, the T2 helps maintain optimal control over energy consumption (Note: The energy monitoring feature is only available in wet contact mode). Leveraging the Zigbee protocol, the T2 features significantly lower idle power consumption compared to Wi-Fi relays, leading to reduced energy costs. Additionally, equipped with a power-off memory function, the T2 retains its last state even after power interruptions.
[Safety and Installation Flexibility] The T2 supports overheat protection, overload protection, and a customizable power limit that automatically shuts off the device if consumption exceeds specified settings, directly safeguarding your home and energy footprint. Additionally, it can be installed near a light, behind a switch* or wall outlet, and includes a DIN rail mount. (*Note: The T2 dimensions: 1.80 × 1.89 × 0.95 inches)

Simple & extraordinarily versitile. Kind-of made me a big fan…
The use cases for this are nearly endless. I’m using two of them to control the boiler-driven radiant baseboard heating in my home. Because these kind of heating systems have a simple two wire thermostat, the fancy Ecobee or Nest wont work to modernize the controls. So, I bought these and I have to say, I love them. With Matter, Apple/Amazon/Google, and Home Assistant, you can pretty much do anything you want with these from easy automation in the apps, to more advanced JSON-based code.I like them so much, I’ve bought a couple more to just have on the shelf in the garage. I think I’ll smarten my rooftop evaporative cooler next spring with them (as there are zero “smart” controllers for those on the market as well).Couldn’t recommend these more.

Pretty reliable but the firmware and documentation are lacking
I’ve been using this for holiday decorations for about a month now and so far it has worked very reliably. But there is minimal documentation, you can’t set a default power on state and it keeps reporting the incorrect output states when off (cycles back and forth between reporting as on and off, sometimes as frequently as every few minutes). I’m using a ConBee II/deCONZ so it might be better/worse on different hardware but this is definitely a bit glitchier than the other Aqara devices I have. The build quality is very good and it’s fairly compact but might still be a bit big if you were trying to fit it into a electrical box behind an existing switch.

Finally, my ceiling fan is smart
This relay is well designed and constructed. It can power larger fans, many similar products do not. While on the large side it includes two independent controllable outputs which is perfect for a fan with attached light. The included, antenna allows the relay to be hidden within a metal fan housing. The package also includes a plastic bracket which I found very useful. I did find the bracket’ which is supposed to hold the relay with plastic tabs friction mount, to need a little work. It seems to work well if attached to a wall but I was forced to mount it upside down in the fan housing. Space limitations meant the relay was very close to the revolving fan blade mounting bracket. The vibrations caused the relay to partially slip out of the bracket, falling to within a few mm of the revolving fan mount. I solved this with duct tape and the installation is now secure.My only quibble is with the antenna with a self sticking pad on the end. Again with revolving fan blades, it is very important the antenna is secure. I cleaned the painted steel fan housing with alcohol. Let the surface dry and pressed the adhesive pad for a full minute. It seemed to be secure. But, after several hours of the fan running, the adhesive failed and the antenna almost became entangled with the fan blades. Fortunately, I caught it in time. I reinstalled the antenna with black duct tape which is not very noticeable in my case as the housing is black.I coupled Aqara Dual Relay Module T2 with the “Aqara Smart Light Switch (with Neutral, Double Rocker). I now can control the fan’s on/off and the light individually. I can preset timed operation and contol both fan and light through the Aqara Ap or through Alexa.

It worked for a few days, now it doesn’t.
It’s always something with the smart home stuff. I even bought the Aqara hub just to ensure compatibility with my network. After hours of frustration in the Accra app and the Google home app, the garage door finally started to work. I have no idea what changed, it just suddenly worked. Then about a week later it stopped working. So I set it up again and it was fine. Then there was a power outage. Once the power came back on a whole bunch of my devices were no longer working including this Aqara relay module.It was a pain to set up, and I don’t remember exactly how I did it and I’m avoiding doing it again so I’m back to having a dumb garage door.

Great for homes with one light switch ceiling fans
Great if your ceiling fans have one light switch that sends power to both light fixture and ceiling fans, now you can send power separately to light or fan.
