TOPGREENER Wi-Fi Relay Module, Hidden Smart Switch for Fans, Lights, Outlets, 120-240VAC, 10A, ETL Listed, TGWFRSM1, Black

This is the ONLY multi-scene WiFi controller I’ve ever found. With smart life compatibly it works with many devices. I’ve installed 3 units, for my daughter’s bedroom where the switched outlet wan not by the dresser, replaced the light switch with this controller and controlled 2 WiFi outlets and asked the topgreener fan controller. I’ve used the wired 3 way switch, instructions were not clear, but figured it out, worked perfectly. Maybe another company will produce a competitive unit but for now topgreener is the only multiple scene controller around.

I have almost 30 devices on my wi-fi network, mostly lights, outlet controllers, sensors, and garage doors. I used this controller in the master bedroom to allow instant access to flashing or just turning on all the lights in case of intruder threat. It also controls a siren. Probably never needed, but nice confidence boost. Easy to set up in smartlife app if you have logical mindset. Wish buttons were bigger, as the labels I affixed are hard to read. Works well, great value.

Pros: Very capable Smart Switch with very good price to performance. Integrated easily with Google Home after installing the Smart Life app. Only requires sigle-pole at 2nd switch.Cons: NOT Compatible with LED nightlight switches. The switch throws out traditional three-way wiring at the second switch location. This switch only requires a traveler and a neutral at the second box, which is great for new installation; but, not so easy for existing wiring. And, the instructions/schematics do not address existing "traditional" wiring. The Solzulamp 3way or single pole LED night light switches are incompatible with this switch. The LED circuit interferes with the Topgreener circuitry.What I did: (I'm NOT an electrician) (3-way switch NOT required) At the second box connect the Traveler "red" to hot side of switch, and Neutral "white" to Neutral side of the "non-LED nightlight" switch. Tie the Load "black" & Hot "black or (white w/ black mark)" together with wirenut.*Note* My best friend "the electrician" figured this out.Final Thoughts: Great Switch that has poor documentation for existing "traditional" wiring. I'm sure this has created some bad reviews of this product and probably many returns. DO YOUR HOMEWORK. New switches have New Wiring.

Update: I have had these switches now for over 2 years. I have dropped from 2 stars to 1. Still no improvement on the wireless recognition and Alexa support. Constant losing wireless connection and constantly losing the Alexa capabilities. I am also reducing to a single star because now this switch turns the lights on and off without us doing anything. Either someone has hacked the system or there's a major glitch. Due to concerns over fire hazards I'll be pulling these switches out and going with a different brand.I have a 3-way switch setup. There wasnt much straight forward wiring info but that's to be expected because a 3 way setup wiring could very in a house. I have had this product for some time now. Didn't take too long to get online and working. The reason for the low review is the switches have terrible wireless receivers. This product has intermittent issues of losing the network. I'm running a high end gigabit router that is probably 15 feet from the switches. The first few times alexa couldn't find them I was able to reboot and get them running, however within the last week they lost network and alexa can only find one of them now. Basically they have turned into a very expensive light switch. Both partners need to get together and sort this out. But our echo can no longer find them and the switches say we have bad internet which is completely inaccurate. Until the bugs are worked out, I wouldn't recommend this product.

It was easy to install, came with clear instructions and connected to my Smarlt Life app and Alexa seamlesly. To my suprise it came with 2 switches. It fit nicely into a 3 gang box I had. Throught the smart life app, I have it set to go on and off a certain times of the day. This is the second TOPGREENER switch I have purchased and both have worked great. The other is a wifi dimmer switch and it has worked flawlessly for 2 years now.**EDIT**Make sure you replace your other 3 way switch with a single pole switch. The instructions show this but don't clearly call it out.

I'm very satisfied with this switch. One of the two switches was defective when we got them, but Topgreener's customer service quickly remedied it and sent us a new one. The installation is very easy so long as you have some basic electrical skills or know how to watch how-to videos. Both of mine were installed in 2-gang boxes and had to add pigtails for the white and ground wires. But it is very easy and quick.Both switches work really well, and they integrate with Alexa, Google Home and IFTT easily. For use with IFTT, they have to be set up using the smart home app called Smart Life and not with the Topgreener app. The setup is the exact same for both, however, and very simple.One of my switches controls a bank of fluorescent kitchen lights and one controls an led patio flush mount. Both work with no issues.Especially because these do not require a hub, I've recommended them to friends.I do wish that the app used for setup have 2-factor authentication though.
