4CH WiFi RF Wireless Switch Relay,Inching Self-Locking Interlock Mode,for Access Control Smart Garage Door,Compatible with Alexa Goolge Home

Save me a few dollars...I was thinking on buying OEM smart garage door opener...good I tried this one...very easy to install, a lot of functions and very affordable price.

If I can do it, you can do it too!!! Power supplied by 1) generic doorbell or HVAC Furnace transformer, 24V 40VA class 2 type. You'll need to buy 2) Swimables 180 Degree Rotation 3-Port 24 Volt AC Universal Valve Actuators or something similar to fit your valves. You need basic electronic experience to do this. And a plastic waterproof box to mount it in. Used this and several KTNN-Wifi-RF-30A 220V Relays (to turn on/off lights, pumps ect), and also 1) DH101 wifi spa/pool heater controler to automate my system. Spent about $400 (all from Amazon) not the $4000 my pool dealer wanted to do this!!!

This really look like a very nice unit, but unfortunately, I was unable to pair it with my Wi-Fi nor Bluetooth. I set the Wi-Fi to 2.4 GHz and despite pairing numerous other switches, this one simply refused to pair nor showing up in the bluetooth scan. Even with the help from the support people...can never get it to pair. This does not make sence Feb 17, 2025 7:45 PM Hello, thanks for your information.it works with ewelink app.if the enclosure with din rail mount? If so,please remove power source firstly,then power it up,to check if light will flash 2 short 1 long? If so,enable your phone Bluetooth and open ewelink app,select Bluetooth pairing,it will find your SSID automatically,enter your correct wifi password. Please kindly noted it supports 2.4G wifi only,when pairing,make sure to put it close to your router,your phone have to connect to the same 2.4G wifi,and check phone settings to allow ewelink app to use location service when needed Look forward to your comments

The product it self is super good i love it but it does not have the ability to be operated like a push button on voice commands, i have tested it on google aswell as alexa and you can for example not say 'Hey google open the garage door or close the garage door. Instead you have to say turn on the garage door every time to activate the switch and then th internal functions of the switch will turn it off after a few seconds that you pre program.

It looks neat, used to control irrigation in my glass house. Can water my plants remotely from anywhere.

I've purchased 2 of these switches over a 2 year period to control a thermostat in a cabin 350 miles away. After about a year the first switch went offline. I purchased another switch to take with me to replace the failed switch. I replaced the switch, installed the new one and things worked fine again. I brought the old switch home and tried it again and it started functioning. After a year the new switch failed. I replaced the new switch with the old switch but I got no indicator lights. The switch can be powered using 7-32 volts or using a usb cable. When using it in the cabin I was using the 7-32 volt input because the thermostat is powered by 24 volts. When I checked the old switch at home I was using the usb powered input. It appears that on both switches the incoming power through the 7-32 volt has failed but the usb input still works. Just a word to the wise in case you have a power failure. Needless to say I hope the company will address this issue.

I stumbled upon this little gem awhile looking for components to assemble something that this thing does it all. It worked perfectly since I got it more than one month ago and is still working perfectly daily controlling my pool valve actuator.

Purchased 2 of them end of March 2020. Using them both with my ham radio satellite station, to control amplifiers, relays, etc.. very pleased with the result. They are working very well.

I wanted Wi Fi control of 12 volt power supplies in my observatory managing dew heaters and other 12 volt devices and this neat little unit delivered four control channels and a decent Android app that did exactly what I wanted . Considering the very good price and ease of use I can heartily recommend it as fit for purpose.

After trying 2-3 cheap PCB relay boards, but not being able to get their apps functioning, often with zero instructions and issues adding to common IoT apps, this board was a breeze to install and sync to Google Home for control. I use mine to control multi-room audio, and it's been flawless for several months, never going offline, and with almost no delay in triggering the relays.

What a cool device! I have to say this was one of the easiest smart devices to setup! It looks great in the case too. Perfect for home automation or hacking. Don’t bother with the expensive relay packages.

Easy to setup and install. Lots of applications

Very handy product - easy to install, works well. Shipping was fast. Thanks again
