Review: 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.
Review: 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!!
*by B***R on April 12, 2025*

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.
