2CH WiFi RF Wireless Switch Relay,Inching Self-Locking Interlock Mode,Compatible with Alexa Goolge Home (Smart Life app WiFi RF Bluetooth Relay)

I had a hard time getting it to connect to my 2.4GHz wifi, and I'm not exactly sure what I did to get it to finally connect.Now that it's online, everything is working great. I added it to google home, and now I can just say "hey Google, turn on the ventilation".

easy installation and smooth operation

Pretty nice relay. It’s actually two in one. However, Alexa will only activate the two relays together. Not a huge deal in my case but it would be nice if I could set the two relays as separate devices in Alexa.

Obviously, the designers of the case and the board were not in communication. You're not able to plug a USB into the relay board unless you do not use the case. The case housing blocks the micro usd cord form being inserted. I wanted a case to protect from dust and for aesthetics. I'm very disappointed in this design flaw. It's kind of crazy.

Very easy to program , saved hundreds over buying a propietary controller.

This does not use the same app as my single relay mhcozy so at first I could not get it to work. I reread the instructions and found out that I had to down load Tuya smart. I bought this one because I thought the initial one I bought was defective but as I said it requires a different app

Super cheap

Registration with eWeLink app mostly straightforward. I configured Interlock mode because I will be driving a linear actuator (when it arrives) to open/close a kitchen rubbish bin cupboard. Expensive, and a bit larger, compared to basic Sonoff WiFi switches I have, but I needed the dual relays with exposed contacts to wire up the linear actuator for reversing motor polarity for push/pull action. Power input can be AC/DC which is unusual, but flexible. I am using a simple mains to 12V DC power supply rated at 2A, which should also operate the 20W actuator.

This a rare beast - a low cost IoT device that works as advertised!You set it up with the "Tuya Smart" app, which is easy to do. There are one or two slightly odd English translations in it but nothing too confusing and it looks well written.Once connected to WiFi and paired with the app you can give it a name and control each relay separately. You can also configure them act as momentary or latching using the mode switch on the unit itself, which is very handy. Having done that it's easy to connect it to Google Home using the Home app.The ability to also control it with a 433MHz RF remote is brilliant and should make it much simpler to integrate with a home automation setup where it might be controlled by app, voice (Alexa / Google Home), timers and/or a remote control.The two SPDT relay outputs would make it great for controlling something like an electric gate or garage door, but you would need to carefully think through the security implications of setting it up to control something that allows access to your property.

This 2ch garage door opener has a very nice range of power voltage (7-32V).The 10A max current on the relay is quite enough for most of garage motors, and if you need more powerful relay, just add another one to the circuit.Very easy installation (in the garage or other place you need 2ch power switch.The Tuya app works quite well with this smart switch - thousands of conditions and sceanrios could be created.The only thing which bothers me, is the microUSB port under one cover - i could not be used for anything - you cannot connect the microUSB cable in it - but maybe it is only for firmware upgrade or programing.Anyway, very nice 2ch switch - low power. Could be used in a wifi network with Tuya App or directly with a generic 433MHz remote control.

I ordered this smart switch to control my garage door. The door worked with remote controls that my family was always missing. Now it works with the eWelink App and we can open the door via the phone anytime and from anywhere. And it’s exclusive when I’m not at home and I receive an order from Amazon, the postman calls me and I open the door wherever I am so he can leave the order safe and close the door. And it also allows you to turn on the garage light when we open the door. I don't know details on how to install this switch, as I asked the electrician to do it, but it took a few minutes. Highly recommended.

not yet set up but seems to do the job... it works when up
