MHCOZY WiFi Wireless Smart Switch Relay Module for Smart Home 5V 5V/12V?Ba Applied to Access Control, Turn on PC, Garage Door (1CH Smart Life app)

My entire house is integrated with the treatlife app, so it was nice to be able to connect this device to their program. Because I’ve already connected treatlife with Alexa, it immediately connected to Alexa.Something to note because it’s not super clear: it is a relay. If you’re using this to run a low voltage device off the same power supply, this does not work as a pass through. It does not provide voltage on the other side of the relay.What you need to do is jumper or pigtail a low voltage wire to the common terminal from the positive on the power supply. Then hook the negative of your device to the power supply negative and the positive to the NO (normally open) terminal. The relay will open and close that contact and it should work as a low voltage switch.Apparently the relay is capable of running high voltage as well. Great for small spaces where you’re either controlling a portion of a device (given you have access to a 7v to 30v system within the device).I can already think of a few things I’ll be using this for. Especially if I can find a dimmable one 🤩

Facile da configurare comdo per la doppia alimentazione, la app da utilizzare almeno per la mia esperienza consiglio tuya.Per apertura cancelli si può anche temporizzare il relè.

Produit qui fonctionne à la perfection, d’installation simple et d’un prix imbattable.

Having lost a fob to the garage door, I explored these wifi switches and I am so glad I did. 2 of these, total cost of just over £30, has now given me wifi control on my phone and it was easy once you identify the connectors you need to connect to (just one common and then the other 'Normally Open' connection to the relevant connector (up or down). Note, I needed 2 because my old garage door shutter (a 20 yr old elero) is controlled by a fob (no wall switch) but clearly it had to be switched somehow. I did explore the 'Meross' route but had a 'lazy' reply saying they couldn't confirm if their product would work. Having explored a bit further, I was convinced this would work and indeed it does perfectly. My type of roller shutter door has a connector strip numbered 10 through to 17, with 12 being the common, signalled by a continuous solid line underneath on the surface mounting, 13 to bring the door down, signalled by a 'switch' icon and 14 to lift the door up (signalled by another switch icon) all icons printed on the surface mount backing. The app was easy, just scanned the QR code and installed. I had no problem with needing to change router settings to 2.4ghz, it just worked first time for me. Set up both switches on the app, named one 'Door Open' and the other 'Door Close'. Changed the inching settings under the 'Timer' function to 2 seconds so the switch immediately turns off once activated, because on my old door the fob had just 2 buttons which needs the alternative button to be pressed to end the action of the first button. Finally put the wifi relays in a separate box under the current controls to prevent any issues by trying tocram in the relays to the original control box. So far so good, great value for money.
