Plugged in a usb cable. Opened the Smart Life app. Tapped + to add a device, and there it was. Connected to WiFi, and was added to the app. If it works well, I'll buy a couple more. The first one's to use as a garage door opener.

It's versatile and simple to set up, and it just works. Connect it to the garage opener wall switch, power up via the built-in USB port, and you've got a reliable Wi-Fi control of the garage door.

Really cautious based on the "regularly returned item" warning, and the reviews weren't great.Already had Tuya app installed for some smart plugs. Wanted to be able to open a driveway Gate from the house (no 'clicker') or from a range beyond the clicker.. Setup was SIMPLE. Directions are good (although you may need a magnifying glass to read !) , used USB port to power and connected to Gate control. Built an Alexa routine and done. I believe there's a timer function built in but couldn't find (once the circuit is closed it DOES need to be re-opened), but the Routine with a WAIT step solved this. Gate manufacturer offers a similar product for $90.

Easy setup, directions not the greatest but easy to figure out. One second momentary closure works well for garage opener.

If you are buying this to control an All-O-Matic or Lift Master entry gate, it will work but if your gate auto-closes after some time, you will need to build a custom routine in Alexa/Google Home that toggles the switch on and then off after a few seconds. If you do not, the gate will not auto close because the device is built to be on or off which works fine for a garage door. I created a custom routine where the voice command "move the gate" will initiate the command "turn on the device (I named "Gate"), pause 5 seconds, and then run the command turn off the gate. Without the pause, it sends both commands at the same time which causes the turn off step to fail. Google Home does not appear to have a pause feature like Alexa but you can add a step to have the google say a custom statement like "OK, Moving the gate" which by default delays the turn off command while it's speaking.

Certainly a DIY, yes instructions to small to read. I suggest a link to PDF or something. Missing USB type as well.Update: Found a plug so I was able to test a mobile use. It was functional enough to go ahead and rough fit and test reliability next. Set up was simple after downloading QR link and starting up with Google home. Going to try to find a remote next.

Great little unit that instantly connects to the Tuya app, I use mine to control a high power 12 volt water pump so used the units onboard 10amp relay to switch a larger 40amp relay which runs the pump. Very versatile little unit with limitless possibilities when paired with the Tuya app and Alexa

I bought this to remotely control (with phone and Alexa) a variable flame fireplace using a standard wall "on/off/on" rocker switch and 6v DC adapater. It took a little bit to figure out the correct wiring configuration, but once I did this works great! Using these parts cost a LOT less than what the fireplace manufacturer (Peterson RealFyre) wants for their remote wall switch or manual remote, neither of which can work with a phone or Alexa.This relay connected quickly to my existing Smart Life app. I do have Smart Life coordinating with SmartThings app, but SmartThings only shows this as 1 switch rather than the 4 relays. No problem though... I setup the relays using "scenes" in Smart Life and those were immediately recognized within SmartThings and Alexa. (Now I can just say, "Alexa turn on light flame" to turn on the fireplace, "Alexa, turn on smaller fire" to turn it lower, "... extinguish fire" to turn it off, etc.
