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.

I have used this great little relay to control gate openers (dry contact) and to power cycle 110 volt devices and it works great. The instructions provided with the product are not good but the Aqara website provides a lot more information and ideas of how to use this product. I use a 24 volt AC low voltage transformer to power the relay and the Aqara M2 hub. Overall this is a reliable product.

Huge. Relative to most compact in box switches this one is near 2x the size of others I've used before.On the other hand only 1 of those were dual relay but still 1/2 the size easily fitting behind most switch or outlet types.For USA exterior usage to control 1 duplex outlet (each receptacle on a relay) I had to install a dual gang pvc surface mount box with wet service in use cover box just to fit this giant in 1 gang space.It's too tall wide & deep to fit along side or behind any outlet...might fit very snug to a simple single dtsp switch 🤷‍♂️.If you were to install it in a deep plastic single gang new or existing construction box you may be able to get it to fit, but I'd recommend using stranded thhn wire over solid romex for the terminations between device and fixture.It looks and feels substantial so they get kudos there. In the US we really don't use din rails all that much but I certainly have had cases where it could come in handy for other purposes.Functionally I like it. Being it's zigbee saves some wifi bandwidth in a residence with 200 plus ip devices. The switch or sensor connections give it additional flexibility for usage. The power tracking, scenes & automation abiliies work as expected.Also appreciate substantial lugs which can accept 12 gauge wiring and sufficiently torque it down without fear of stripping the threads.It would be nice if set up (schematics) were included in the print manual since the aqara documentation for it on their website is near impossible to locate.Still feel it's a skoche overpriced for what it is. But it definitely tries to make up for that by doing it's job well while being we constructed. If they could miniaturize this more perhaps by going w SSR or triacs over mechanical relays it would be a real winner.

gives me two separately controllable relays with either wet or dry contact mode. easy to wire up if you have any electrical experience. use it to control a light and exhaust fan that was wired together in my bathroom.

Works as advertised. Used it to integrate the legacy garage door into my Smart Home. I could have paid $40 for a regular garage door remote but with this I get lots of additional features for $35. Primary ability is being able to disable the switch/garage door remotely so even the normal interior button doesn't work. Now I have to figure out what else I can automate with this thing.

I’m a smart home guy. Mainly, I use Apple Home as my choice for user interface and Aqara is awesome with Apple Home. I also love smart relays. I am a huge fan of Shelly relays, however, Shelly is not user friendly if tech isn’t your thing and for someone like my mother who lives by herself and occasionally forgets to close the garage door when she goes out of town. She needed an easy solution to make her dumb garage door opener smart. For way less money and zero subscription fees than buying something that a brand like chamberlain offers out of the box. This relay, was able to solve this problem and it works flawlessly. I only wish it existed before I replaced my garage door opener.

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.
