Reliable inexpensive hardware to control remotely any low voltage actuator
Very easy to install the app. I can control my gate through my phone app. Definitely worth the money. Good quality, it’s all you need for turning something on/off remotely. It works with low voltage devices, such as garage door remotes or relays. I like the NO/NC option offered, you can control both types of relays. Connectivity is good, it’s far away from the wifi router, but works like a champ.

Affordable smart gate.
I bought this to make my regular gate smart. At $12 the price is unbeatable. It 100% does the job no problem. I connected it through the SmartLife app and then to Alexa. I’m able to use it with Alexa routines flawlessly. I wired it to one of my regular remote controls and put it in a waterproof box outside. Great connectivity, it never goes off-line. Nice small footprint with a sturdy enclosure. I’ve had no issues at all. I’ve actually ordered another one to make the door at my office smart.

Works with power entry gates when you create a custom Smart routine!!
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.

Almost perfect
This works pretty well so far and since I'm using it with a little ear actuator, I appreciate the picture included of how to wire it up. Easy to set up using the Tuya app. On the cons, see puc, but there isn't enough space for the USB micro plug when using that jack.

Well Made

WARNING - this device will lose its ability to connect to wifi after a short period of time
I had high hopes of this, as it looks well built, however, exactly 2 months after the purchase the device began to loose the wireless connection (as others have reported) at first a reboot would cause it to reconnect, but after a couple of days it would no longer connect to the wireless at all. I have another brand relay purchased at Amazon which is located in the same location and it has kept it's wifi signal without failure for over a year. Based on my experience and the reports of others, this brand of relay will eventually loose its ability to connect to wifi rendering it useless, and since the failure takes place after the return window, I am stuck with an items that is useless. To be fair the bluetooth still works, but it does not serve the purpose for which I purchased as it is advertised as controlled by wifi.

Awesome device to automate front gate despite mediocre instructions
This device is absolutely brilliant. I attached a wiring diagram because the diagram from Amazon & the instruction manual didn't make sense to me. I also downloaded the Tuya Smart app to get it setup and linked to Amazon Alexa. After setting up in Tuya, need to goto "Timer" & enable "Inching" in the app. I set mine to 5 seconds. Now when I'm in my house, I can say "Hey Alexa, Turn on Gate" which will both Open & Close the gate. I can also open & close from my phone wherever my phone is connected to the internet via Alexa App or Tuya App. I'm considering getting the 2 channel version for my 2 garage doors if for no other reason than to show off :^P

Works great - using for variable fireplace switch
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.

This worked great. It allowed me to create a smart actuator that opens and closes my duck house door via the Tuya app. Connection was quick and easy, it worked out if the box. It's compatible with the Tuya app but not sure if it works with any other app. You can set it so that on one relay can be on at one time. And you can use the Tuya app to create automations. Wifi distance seems great this is about 5 meters away from my nearest WiFi hub and through an external wall. Great value for money as you get 4 relays.
