Smart Single Live Switch

We have a number of wifi wall switches and receptacles throughout the house that we have interfaced with Alexa, but until now I had not tried inserting one in any of our 3-way circuits. With 3-way wifi switches costing about twice (or more) what regular single pole switches cost, we had focused on the light circuits having only one switch. However, reading the vendor's description of the Moes switch, it sounded like they may have circuitry that senses current actually flowing because they claim that in many cases only a single switch is needed for a 3-way circuit. So, I recently purchased one to check it out.The answer is: this switch works great as a single wifi switch in a 3-way circuit without needing to change the existing second switch as long as the neutral wire for the circuit is available in the box that will contain the switch. There will be circuit wiring configurations where this unit can't be used at one end of a 3-way circuit because there is no neutral wire available, but assuming you select the box where either power enters or the load exits (or both), it will work fine. This switch has connections for line (or load), neutral, the two travelers, and ground. The 3-way circuit where I've installed this switch has wires for both line and load in the same box (making it a tad crowded), with the other switch simply switching power between the two traveler wires. With this configuration, I had to install the Moes switch in the more crowded box containing both line and load wires (again, because the neutral wire for the circuit is available).I connected the Moes switch to line (power), neutral and ground in the box containing it; connected the two traveler wires to the cable running out to the distant existing switch (red and black wires); and then connected the returning switched power wire from the distant switch (the white wire with a couple of black electrical tape stripes wrapped around it) to the load. FYI, if you have no idea what I'm talking about, get some help! :-)In this configuration, the Moes switch knows when the lights are being powered and when they're not, regardless of switch positions. So switching the distant switch in either direction will change the state of the lights from whatever state the Moes switch is in, and if you tell Alexa to turn the lights off or on, they will always go off or on correctly, independent of which position the distant switch happens to be in... just like 3-way switches are supposed to work.I more recently installed another of these switches in a 4-way circuit, and it also works great in this circuit with the other existing switches. This circuit is wired with the line wire entering one end of the three switch chain, and the load wire (running to a string of recessed ceiling lights) exiting the far end. The remaining midway 4-way switch simply exchanges power between the travelers. Since neutral is available in both end boxes, I installed this switch in the box nearest my wifi router. It could not have been installed in the box containing the 4-way switch as neutral isn't available there.In truth, you probably CAN install this switch in ANY box associated with a 3-way, 4-way or more-way circuit because ground is always available in every box (at least since the 50's), and neutral is nominally at the same electrical potential as ground, barring any wiring failures. However, using ground as neutral is not code compliant, nor is it generally advisable in some circumstances. Ground wires are not intended to carry current as part of a circuit's normal operation, so don't do this... just select a box that has neutral available.Set up of the switch was straightforward, although it took two attempts to get the app to see it for some reason. But on the second try it configured correctly, and then Alexa connected easily. The app itself works well by itself for remote control if you don't do Echos and Dots, but with Gen 2 Dots selling for $20 right now, there's no reason not to set up voice control. We've had this switch in use for about three weeks and it has operated dozens of times with no issues.The only real issue with this switch is that it's face dimensions are a few thousands larger than a standard switch plate, so it's likely you'll have to trim or file the switch plate hole a small amount to get it to fit. While it's an annoyance, it's easily done. Actually, a second minor concern is that this switch has five short wires coming out of it rather than having "ports" in which to clamp wires like some other wifi switches... meaning you must use wire connectors to connect it into the affected circuit. The downside of this is the amount of space these wires and connectors may require in some installations. One of my installs is in a 3-gang box containing three 3-way switches fed by two different feed wires, and it was a bit of a challenge to get all the wires tucked into the box.Hopefully it holds up well over time. Assuming it does, I highly recommend this wifi switch for 3-way applications.

I bought two of these switches because it is one of the few options for Wi-Fi light switches without a neutral wire. On first impression, the quality of the plastic used to make the switch housing feels extremely cheap. The light switch itself felt sloppy at best and had to be pressed a few times to get it to work. I installed one unit and it was dead on arrival. I switched it out put the other switch in, and that one worked fine at first. I downloaded the app and was able to connect it to my Alexa and home Wi-fi without too much hassle, so it has that going for it. After a few minutes, it lost connection with my Wi-fi and I could not control it with my Alexa. It did this several more times through the day connecting on its own and then a few minutes later would lose connection. The issue was not with my wi-fi as I have a very strong signal and the switch was approximately 10 feet away from the router and the Alexa unit. I was willing to live with it but the next day when I tried to turn my lights on the switch was dead flipped it on and off several times and nothing. I installed the old switch back in and the lights worked fine so clearly, the problem was the switch died. I’m not one to really write bad reviews. I know luck of the draw every once in a while, you get a dead product no fault to the manufacturer just happens in larger-scale production. I usually just return it and get a replacement; However, the fact that two of these failed on me and the overall cheap quality and construction, I felt I had to write a review so that hopefully no one else has to deal with the cheap product that wasn’t that cheap to buy. I ended up just running a neutral wire to my light switch and using a KASA switch from TP-link and I’m glad I did. It was more work for me but the switch is 100x better quality.

I am not sure if I should give 4 or 5 stars. This is my second one. Bought this to replace another one fron this brand that only last a year. I like that this one does not require nutural line because my old house does not have it. My old one disconnected montly. But I found out that my internet connection was not stable. I just had the issue fixed. I hope this one wont do it. I will come back to update and reduce stars if it has the same issue.This brand/app connect to Alexa easily. Make it easy with my house design. I dont have to walk around to turn on or off the light.

good switch: 4 stars only because app pairing is a challenge...needs to fully shoot down 5ghz frequency on your router. by default, routers broadcast both frequencies simultaneously...

The media could not be loaded. I live in a 100 year old house and all of the wiring is two-wire with no ground so finding a switch to work without the ground wire was a challenge. I read the reviews and saw that some people struggled with connecting but I have a software engineering degree so I thought I could figure it out. One thing to be very sure of, is that you connect your phone to a 2.4ghz wireless network when trying connect the light switch to the Moes app. My wifi network will automatically choose the network 5ghz network on my phone and I couldn't select the 2.4ghz. I had to create a second network SSID and I made it a 2.4ghz only network connection. That enabled me to connect my phone directly to the 2.4ghz network. Once I did that, the Moes app connected the device and it was a breeze from there on.

The media could not be loaded. That which simply does not work, when connected it seems to work as a normal switch, but when you try to enter the pairing mode to make it a smart switch, it fails to connect.Yes, I let the capacitor charge, yes, I have it wired correctly. Yes, I know the password for my wireless. Yes, it’s a 2.4 channel. Followed directions perfect. At least 5 times. Just always fails during. WiFi set up.Edit: upped to 3 stars because it’s working. But only 3 because they are janky. The trick is to let it stay plugged in for much longer than the recommended 7 minutes. And when you’re pairing. Pair really fast.
