LEEHUR Sonoff 5 Pcs Smart Wifi Switch Wall Timer Switch Smartphone Remote Controller, Compatible with Alexa

I purchased these myself and was not given anything in return for this review. I am leaving it to let you know how good these wifi switches are and to explain how mine are setup and what they do for me with ease and what they can also do for you and beyond.I wired these up a few days ago and appear to work very well and are VERY EASY to setup. My only suggestion would be to keep them within 75 feet of your wireless router if it's not high power. If it is you can go beyond that without issue. Remember the load capacity is 10 amps max so you can only pull 8 amps continuously which is fine for lighting and even pumps depending on size. One is running a water fountain pump in my front yard which is 1/3 hp. The second is running my landscape lighting around my entire properly. I have them energising a 20 amp contactor which has 120 volt coil and the contactors are rated at 20 amps continously so no néed to derate 20 percent off the rated amperage in this scenario. Oh did I mention they DO work with Alexa? "Alexa turn on water fountain" and she does it while confirming. "Alexa turn on landscape lighting" and a second later its on while she confirms they are now on. Just do a google search and you will see how highly rated these wifi switches are and how diversified the usage applications are. You can also set turn on and turn off times any day of the week and set schedules which appear unlimited in configuration. Wiring is simple, hot and neutral in and the same out. Programming took about 30 seconds each using the eWELink app on android and I have it set up to work on 3 android devices, my 2 cellphones both Galaxy S5's and my Samsung Tablet without hitch. If you have the app open on 2 devices and use one to turn a device on the other in seconds shows you the device is now on. They are very compact and definitely could be used behind light switches but this is not a 3 way wifi switch so you'll need to be creative with how you wire it including wiring it to a 3 way switch in an untraditional method to feed a switch that is in the off position.Pros-Very easy to setup to your wifi with the android app.Range us surprisingly long considering such a small compact device.Options are almost unlimited with your creativity.While switching on or off it is almost silent with an ever so soft click.Device has programming options you can search for online (wink wink) allowing almost infinite installation options.Oem app is good and very well laid out.Integration with Alexa takes maybe one minute to accomplish but Google the process because it includes no instructions.Cons-With the android app it will not upgrade the firmware which the app tells you is available. Once clicking UPGRADE FIRMWARE and selectin OK it does nothing at all. I do not know what the upgrade accomplishes or adds but I do know these can be flashed with other firmware from around the web allowing even more options for home automation and compatibility with many other apps if you decide to. The configuration file can also be edited (search online for how to) allowing even more flexibility with your projects above and beyond its stock abilities though that and a firmware change would likely void any warranty the device has.Be extra careful when tightening connections on the switch itself because they are delicate it seems and do not over righted them or they may break.Conclusion: These wifi switches are a very low cost way to add wifi control to almost anything if properly setup and are very easy to integrate into almost all lights and or appliances. Alexa compatible! Yes for under $13 they are! (An auction site has them even more competitive) No other apparatus comes close to the flexibility of installations you can accomplish with this WiFi switch. Since buying the first 2 I added even more. One turns my outdoor shed lights on at dusk and off in the morning. I added another to turn my pool pump on and off on a schedule which saves me on my electric bill each month and are so much easier to change times compared to an Intermatic timer. Now think about what I've used them for and consider your possibilities! I am day and night lol

Setup was a breeze. I use a dedicated wireless access point for my smart devices to reduce load on my main wifi network and to help isolate issues should they arrise. This switch went out in our chicken coup to control lights for feeding and egg collection in early morning and heat in the winter. The temp probe is used to monitor outdoor temps and activate lights automatically in winter for freezing temps. We use Alexa on our echo dot to control the lights for feeding. The only issue I ran into is there is no ability to toggle the switch on or off while in auto mode and I cannot set the switch to control itself via the scenes feature leaving the only option of getting another th10 and probe and use that device to control the chicken coup via a scene and retain manual toggle abilities. I picked up a waterproof box from Lowe's and placed the switch inside that to avoid moisture damage. some say these are not user friendly but i think anyone with a basic understanding of electrical wiring and knows their way around a smart phone can use this item with ease.

I have my frontage lights that come on @ dusk and shut off at midnight on a cheesy wall switch timer that lasts for about a year until it needs to be reset manually. After the 3rd replacement, I found this online. It works extremely well thus far. The app is intuitive and easy to use. The only downside is that the module can only handle 10 amps. I'll repost after Christmas time and I'm able to test it under a greater load than 4 fluorescent bulbs. I'll probably get another one to run my attic fan.

The switch only works with 2.4 GHz WiFi. I've got Google Wifi set up in the home, which broadcasts at both 2.4 and 5 GHz, but the switch isn't able to identify the 2.4 GHz signal that the Google WiFi generates. Repeated attempts to set it up with the eWeLink app only resulted in the app giving me the alert that the product "only uses 2.4 GHz". For whatever reason, it couldn't "see" the 2.4 GHz.A Google product forum thread talks about this issue - apparently, there are a host of 2.4 GHz-only devices that can't connect easily to the Google WiFi signal. But a chat with Google support provided a two step solution!1) I set up a mobile hotspot on my phone, and gave it the same name and password as my home's Google WiFi, and the switch connected successfully to the temporary WiFi network my phone was generating.2) Then I shut off the hotspot, and the switch looked for network again, and THIS time around, was able to ferret out the 2.4 GHz signal emanating from the Google WiFi router. It was now able to "see" Google's 2.4 GHz signal after being introduced to the identically named, temporary network my mobile hotspot created!So, it works great now. I connected it to my Google Home and am able to issue voice commands to Google Assistant shut the device on and off. I have it connected to an exhaust fan in the garage so we can safely warm up a car with remote start for a few minutes in the morning.Some users have pointed out that the switch is not that sturdy, but I think it's built well enough for certain uses. I would NOT use this, for instance, to interrupt an appliance or a lamp cord. The wired connection wouldn't withstand the rigors of everyday use.Your wiring is connected to the device with tiny circuit board-style screw terminals that are not meant to be stressed in any way. While there are plastic pieces that screw over the terminal connections and clamp the wires in place, I wouldn't trust the switch's housing to be out in the open, especially where foot traffic might be possible. This switch would be better off protected, maybe inside an appliance's housing (if possible) or used in conjunction with a wired device in the wall, like my exhaust fan, or to power an outlet.I do plan on installing drywall over the void in my wall, but before I do that. I'll put the switch in a blue box directly under the wall switch and slap a cover on it so it can be accessed after drywall installation. It's never a good idea to bury something like this in the wall where you can't get to it. Plus, that's against code. It will fit, diagonally, in a standard single-gang blue box.
