Aqara Dual Relay Module T2,Smart Relay Switch Dry Contact Mode for Garage Doors and Boilers,Light Switch Roller Shade Switch,Supports Homekit and Alexa,Requires a Neutral Line and Aqara Zigbee 3.0 Hub

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.

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.

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.

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

Produit impressionnant, et fonctionne bien pour une porte de garage. Il faut cependant utiliser un shortcut dans homekit pour définir un délais si la porte reste ouverte (afin de la fermer)

Instructions not very clear. But works very well. Will purchase another for HVAC fan.

I’ve used this product for a few home automation projects! It reliable and easy to program! Great value!

It is not stated anywhere that the device would not work without a hub. I now have a relay that is unusable. Be careful: I am completely dissatisfied.
