2 channelsWiFi Wireless Smart Switch Inching Self-locking Relay Module, be applied to access control Tuya SmartLife APP,DIY WIFI Garage Door Opener With 433 MHz RF remote control

I had this installed and running in about 15 minutes.I have about 25 WiFi smart devices in my home, and from my experiance I recomend any device that supports the Tuya/SmartLife application as this device does. I say that because Tuya has reciently updated their app thats used by most Smart Home devices to support local (off the grid) integration with Home Assistant, and other Home Automation Software. Also can be flashed with Tasmota or ESP Home.Anyway (For what it's worth) here's my quick install guide.1. Use the Smart Life app (by Tuya), Not the other one2. Use one of your old Cell Phone Chargers for power (Mini USB) just plugs into the board.3. Plug the charger into the Board and yo will see the blue light immediatly, Then Press the (Relay 1) button down until the blue light flashes rapidly. It's now ready for pairing.* Assuming you have installed SmartLife on your device and already connected to your home WiFi.4. Next Hit the add (+) button on SmartLife app and just follow the prompts.5. In like 2 minutes you will be up and running.Each Relay is able to be turned on/off with the App. Also many other automation features on the SMartLife app. Choose what name you like for the 4 relays.Also Alexa will automatically pick up the device within a a couple minutes.In my case, I say "Alexa turn on (or Off) Relay 1" (or Relay 2,3, or 4), the the relay is switches on.Note by default the Relays are set to momentary, so I changed the setting in SmartLife to Stay on or Off.So to sum this review up. I got this device to experiment with some simple scripts to turn on/off not only low power (5-12 volt) and also high power 110 volt circuits with.In my opinion the Board Looks well made and solid, so I will assume it will be reliable.If I run into any problems I'll update my review.But for now A+ Rating on this device..

I originally got the 4 channel and spent over an hour getting it to work... And it run great now... So I added this 2 channel today. AND Spent another half hour playing with it to get it connected.... Flakey things, but once they are registered and set up they are fantastic! Fast too.... Works great with Alexa, and cheap!A few things to do when setting these up....1 - Make SURE your phone/Wifi is on a 2.4GHz... Set up a temp channel on your router is needed. Once you are set up you can use 5...2- Put your phone in airplane mode with just Wifi and location on....3 - Place the device and you phone CLOSE to your router/Wifi source... I'm talking a few feet....4 - If the setup fails or times out, try try again... I may take several times, doing the same thing, for it to work (????)The directions that came with this (2 channel version) shows a picture and directions for a one channel.... Yikes! Anyways, the middle button of the 3 is the pair button... Power on and then hold it down until the LED flashes fast.... On power up the LED flashes twice then one long. This is NOT pair mode.... Constant flashing fast is....Once set up, it works great at long distances and on 5g.Good luck!

So the instructions were great. I would love a 8 or 16 channel version of this device...First you setup an Access Point (WIFI) for 2.4 NOT 5Ghz so rename the WIFI SSID for 5G and not the same name as the 2.4. Then follow the instructions. I logged my phone onto that network when I started and if you follow the instructions with it I was able to do this in 2 minutes minus the reading of the instructions to see how to do this. Also if you long press the APP buttons you can rename the switches. Also you can name the board with a meaningful name. So I just got the other board that I ordered after the first one was ordered. This is really cool. IF you create a Smart Automation you can set it up where if you press the button on one board and then turn relays on on another board. Think of this you have outside lights front and back yards. You can set up control to switch them ALL on using multiple bards via the Smart then Automation and then pus the Plus sign go to When devie status changes select a control and then the switch position then when you turn it on or off then select run device and select the next control which switch and on or off it creates the control. Also go in to the modules and activate the offline notification to let you know if a module is not responding on the network. I set a message sms task so that when the relay is activated it sends a notice and then created another for the off condition.I am having fun with these.So either the bad reviews were a older revision of board or someone that did not follow the instructions. Wish my battery tender monitors were so easy to set up.The main key is 2.4Ghz WIFI if you try to use a dual band named SSID 2.4/5Ghz you will have issues adopting the board can not determine the difference and the WIFI will insist on being right.Home=2.4GhzEverything-else5G=5GhzThat is what you should see on your phone when you setup. Worked very fast for me.I think I want a few more of these. The buttons and the ability to add a remote set are a hug plus. The MODE switch I might remove to easy to change to modes that I do not want to use but that is my install yours may vary.I also check this and it works via cellular across the internet as advertised.Under setting, There is a power on mode when power is applied all relays turn on from a power loss. You can also turn all switches on at once. You can change the device mode there and set the momentary time. unless you set the power on setting when power is returned all relays are in the off state.I did a pretty solid check of the device.I have a project that I am working on that I will try to make a video of you wont believe it until you see it.

The listing for this relay board says it supports IFTTT, but once installed a look at the info page on SmartLife shows only Third Party Support for Google Home and Amazon Alexa. They have not paid their IFTTT support fees. Several manufactures and Apps like EWELINK are no longer paying the fees for IFTTT, so the hardware no longer functions on IFTTT. Control via the SmartLife Phone App is fine. The board is nicely made, and should be fine if you don't need IFTTT automation for the card. I purchased the board for IFTTT automation, so the board is useless to me.
