1 Channel USB 5V AC/DC 7-32V Smart WiFi Wireless Relay Switch Module,Tuya Smart Life app Remote Control,Compatible with Alexa Google Home (1)

Doesn't work with Samsung Smarthings directly, but it is possible to link between Samsung's service and this company's service. Triggering via SmartThings stills work very quickly.

I've got this unit powering off and on a 12v battery powered fence charger on schedule with the app. It works very well for that purpose. The app is very easy to use and has enough features for my use case. The same battery used for the fence charger is used to power this device, as 12V marine battery.No issues at all! Just needs a case for outdoor use as the plastic housing feel light and fragile, and definitely not weather resistant.Overall very satisfied with this product, and may buy more for other uses.

The media could not be loaded. Great product easy to set up works flawlessly with the Smart Life app. Great way to turn the fireplace on and off get rid of the remote.

I use this to remotely trap cats. It can be tricky to program, and I have to usually use a hot spot that is on 2.4 GHz. It can be tricky to pair if you change the hotspot or WiFi. However, it does work good once set up. I had to look up instructions online from other sources to figure out how to change the hotspot last time I used it, which took me a long time. Because of that, I only give it 4 stars. It wish the instructions better explained how to use and program it.

Other brands wouldn’t stay connected. This one has been dialed in without any issues.

Took me less than 5 minutes to install. I had an old 12V DC wall wart to power it. Used to turn the Rinnai control-R wireless box on and off. Works perfectly! It's all I could ever ask for in a wireless relay switch!

I'm very familiar with diy electronics and AC and DC circuits, I've never had an issue with a circuit simply not working no matter what and have done wiring for homes, RVs, and trucks. I've wired in IR and blutooth controlled switches/relays many times. I tried adding this to control my RV ceiling lights. They run off a 12v dc circuit, and the light is 6W with a positive and negative terminal only. The unit received power from both the micro USB plug-in and the 12dc input (not simultaneously) and I could connect to my tuya app and turn it on and off, hearing a click and seeing the led indicator turn on/off, but no matter how I wired it- positive or negative on com, NO or NC circuit, didn't matter, none of the 4 possible wiring configurations worked with either power source connected. So I called Amazon and got a replacement unit which also had the exact same issues. I checked with voltmeter as well to see if it was sending any power, nothing. For now, the ceiling light has been reinstalled into the original circuit design and still functions normally. I understand all items mass produced occasionally have defects, so I wasn't bothered by the first one not working, but to have 2 in a row is concerning and disappointing.

Functional. A bit exposed in making connections and placing.
