[Upgraded Version] Aqara Dual Relay Module T2 with Matter, Requires Aqara Zigbee 3.0 HUB, Dry Contact Mode for Garage Doors and Boilers, Light Switch & Roller Shade Switch, Supports Homekit and Alexa

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'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.

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.

I purchased this Aqara Dual Relay Module T2 with Zigbee for its ability to control a ceiling fan with a light, turning on or off the fan or light independently. It does a great job with that, and it does much more, as well. You can configure it as a dry relay, pulse or switch, for garage doors, gates, and such things. It comes with a stripped and tinned patch wire to connect the load to the two switches for a powered switch, or simply don’t use the patch wire for dry connections. I use the Samsung Smartthings app for most of my smart devices. Initially I had significant difficulty because if I paired the switch to my Smartthings hub, it appeared (and worked) as only a single relay switch. If I connected it to an Aqara hub, which Aqara says is required, I could not make it work with SmartThings. I don’t want two different platforms, so I scoured the Internet and found a third party driver that I could download to my SmartThings hub. Once I did that, this Aqara switch detected in SmartThings with both relays. I was off to the races, with no need for the Aqara hub or its software! This is a very versatile smart switch, and I’ve since purchased more of them.

It is extremely painful to connect this to the hub. And even after you get a successful connection, it disappears after a few seconds.Update after a few days: I was finally able to connect it though I can’t tell why it eventually worked. You do have to press the reset button once for 5s, then watch the hub light. Then do it again. It only connects on the second try.Once it connected and eventually appeared in HomeKit, it has been functioning as expected.

The first night I tried to add the T2 it was hard-wired in a ceiling fan canopy. It failed to be added to hub twice. I removed it and put the wiring all back. The next day, I took an old extension cord and wired the Live and Neutral directly to the T2 as a matter of convenience, this time much closer to the hub, but it failed again. Since I was sitting at the table and not standing on a ladder with my hands full, I saw the app had a message suggesting checking 2-4 things, including that the hub was on the latest firmware. It wasn’t. After the update, the T2 was able to be added, no problem.I’m using it to allowed remote, independent control of the light and fan in an otherwise dumb ceiling fan. Works both in the app and also using the double rocker switch WITH NEUTRAL for a physical remote, having programmed the buttons to operate the T2
