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)

Great relay - it just works. The external antenna gives it connectivity far superior to other relays with just an internal antenna, which makes this relay a great choice for difficult locations. I am using one of these in a metal shed inside a grounded, metallic electrical box (antenna poking out of the box) and found no issues whatsoever.

This product didn't work for my application but the company made it right. Totally change my opinion about them.

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.

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