Mini Smart Relay WiFi Switch, DIY Smart Light Switch Module Smart Life/Tuya App, Compatible with Alexa and Google Home Smart Speakers, support AC100-250V/ DC15-250V/16A (4Pack）

I bought these to use on a 30a contactor for a pool pump. I only used one at the moment but so far it works perfectly. I ran 120v in to the mini switch and since my contactor has a 120v coil, I ran the switch to the coil and when it comes on, it powers up the contactor. It says these can handle 16a but I personally wouldn't put more than 10a thru them and that would only be for a few seconds. The screws are very small, and the openings for the wire are about 12-14awg and up. You would just barely be able to get a 12awg stranded wire in them. However, there would never be any reason you would ever need such a heavy duty wire for this mini switch. I ran 16awg for the incoming and out going to simply power a 120v coil on a 30a contactor. Of course the wires on the contactor themselves are 10awg for the pool pump. These are great if you want to use your existing switch in the wall. Just follow the instructions and you now have a dumb smart switch, or is it a smart dumb switch? The ones I received are for ac/dc. I have seen some that are just for AC and some for just DC. So double check the ones you are getting. I can actually use these on some low voltage projects. These work great with the Smart Life and Tuya Smart app.

Connected easily to Google hub. I didn't want to fish an extra wire and add another switch. This relay turns on a light and a disco ball motor when I tell google to. I didn't even have to use iftt. Exactly what I needed.Update: I ordered 2 more. One controls my porch light set on dusk until dawn and works exactly as programed. It's directly under my long eaves that light sensors don't turn off until around 1pm. This took care of that problem.The other is in my living room connected to a wall sconce. I can turn that off and the indirect lights stay on so there isn't a glare when watching TV anymore. All 3 work perfectly. Fits inside every electrical box.

Very easy to install. Can be wired into your switch or directly to the fixture.

The media could not be loaded.  Works great with Alexa.. If you have iphone, download Alexa, add the switch, and just say "hey siri open alexa" then say "alexa' turn on/off lights/switch.. or just use one of the apps with you fingers..I love the app for these. Plenty of timer and setup options. You can set these too remember there last setting, IE: Wire them just power in, power out, switch in wall will shut relay off..Then when you turn switch back on in 1 second they come back on. (think you can adjust in settings what it does when power is supplied.)The screw terminals are small, and tricky, make suree you got a good littler regular screwdriver.These are small, Easy too fit into a electric box.They do have switch inputs, But you dont really need to use them-CAUTION- DO NOT PUT A POWER SORCE INTO THE S1 OR S2 TERMINALS!. THEY WILL BURN UP.So if your not sure about wiring, electric, just put a power and ground/neatrual wire in, and out, thats safest way. Unless you can wire non-power switches into them go ahead.(it can be done if you read and watch videos on these.) Thou' you dont really need too.They will remeber there last status, and when you put power back too them, they will turn on in about 1-second.The app is great. My favorite so far, beisdes the other sets ive tryed that work with siri, But I actually like these better for complete control threw app. Only takes about 10-15mins if that too hook up, and connect too app.My favorite thing is the timer, and option too have these power on when power is supplied, or stay off. (So if theres a switch powering these they will turn back off even when you shut switch off for a day)I love the fact there small, cheap, and can control from phone, and have timer setting's. great for any light or outlets you need too hide this in too control something from your phone. Idk about hi-amp, like a Window unit AC, BUT any regular lights, or lower amp stuff works fine with these.

Easy to install

Used on our four gasoline dispensers to individually power cycle them when there is a network error.Normally I would have to turn off all four gasoline dispensers by the circuit breaker to do a hard reset. This causes the entire credit merchant system to reboot and wastes about 7 minutes...time I could be selling gasoline!Our gas pumps are about 120' from the store and we do have a strong WiFi network so the signal gets to these little switches easily & reliably.These units must have great internal WiFi micro strip antennas, because they still receive the WiFi signal inside of the gasoline dispenser housing.The option to add a toggle switch is effective too. Whatever state the relay is in, the added external switch allows control of the circuit without using WiFi or a smart device.Using the Tuya APP you have and option to retain the relay's state when power fails and is restored - meaning I don't have to turn all the pumps back on everytime we have a power failure.These switches are tiny, easy to mount, easy to wire and are super easy to implement.Excellent product for IoT do it yourself enthusiast!Two thumbs up.

I had an electrical box packed with 2 Treatlife smart switches and got a Colorock switch to replace one of the Treatlife switches, giving more room for wires.Wiring was straightforward with clear instructions. Once installed I was able to compare the signal strength of the Colorock switch with a Treatlife switch. My Unifi internet controller tells me the strength of the wifi connection for each device. It’s always possible to transit a signal strong enough to reach the device. But wifi is 2-way and the device needs to send a signal back. The Colorock switch transmits back signal that is too weak for my application. It is about 8-10 dBm weaker than my Treatlife switches and this is hugely significant.The Colorock switch worked in a different application for about 3 months then went dead. One died after 3 months

Pues cuando llegó no funcionaba así q no puedo dar una opinión positiva lo tuve q regresar
