MOES WiFi Smart Light Switch No Neutral Wire, No Capacitor, No hub Required, 2nd Generation Single Live Wire Push Button, Tuya Smart Life App Remote Control Work with Alexa and Google Home, Minimum 7W

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.

The media could not be loaded. It works okay...as a "simple" light switch and that would be fine, if that's all I wanted; but I purchased this for the "smart" functions, which this seems to be lacking. It will not stay on in discovery mode for longer than a few seconds..to quick for the app [Tuya]to finish the setup process. Moes doesn't have any solutions and even though Amazon claims that there is product support, they list everything except for this switch. Is it broken? I don't know. I know It takes nearly 5 mins to allow for resets and then the whole process of failure again, due to lack of discovery mode failing to stay on long enough. I wouldn't suggest this, unless you like heart ache, continuous failures and frustration. But if you love that, this will keep you busy on a boring weekend I guess.

This was easy to install. It was nice that it included stickers to label your existing wires which makes installation a little easier. It also comes with all needed hardware. It replaces just one of your two existing three way switches. Works with the Smart Life app, as does many of the cheap Chinese smart switches. Smart Life integrates very well with Alexa making it very convenient to use by voice. It does not need a hub to operate, but it also appears to not work with a hub if you prefer the benefits of running a hub yourself. I don't use a hub so I don't care myself. The only negative thing that I see is that it advertises a countdown timer. While it does have a countdown timer, that timer is just a one time use. You can't set it to always turn off five minutes after turning on. I would knock it down half a star for that, but half stars are not an option.

I do this for a living; which is to sell IoT! And if there is one area that needs serious improvement that would be product setup. This one is no different- install was straightforward and I needed this configuration (without a neutral). After the App download, it took forever (3 tries exactly) before the device was found & setup. Don’t be fooled by the simplicity of the 5 sec hold for device reset. It takes a few tries and some decisions on the fly. Pairing with Alexa was a breeze though and the rule setup is easy (in Alexa).Although this is now a part of the home, I am only giving it 4 stars and my search for that ideal user experience continues.

Great product.

I thought I found the fix all for my 1940's era house. Install went fairly easily, the hardware is attractive and seems to be made with good quality. After installation and flipping the breaker back on you have to wait a few minutes for the internal capacitor to "charge" before the switch will work (this is mentioned in the instructions). Low and behold it worked great, I added the unit to the Smart Life app, Alexa recognized it straight away and I was good to go. I used it multiple times over a period of 2 days and then the switch completely stopped responding. Both to physically pressing the on/off button and to anything smart related. I flipped breaker multiple times, removed the switch to check wiring and nothing. I ended up reinstalling the original Lutron dimmer switch and lights work again. So whatever happened, the switch appears to have failed, luck of the draw perhaps, because I was very happy with the quality and function initially. Luckily for me this motivated me to crawl around in my attic and I've identified a relatively easy way to get a neutral wire to this switch location, so I'm just going to go that route. I returned the defective switch. I would have tried a replacement unit had I not decided to run a new neutral wire, so your mileage may vary. The switch did function flawlessly when it worked.

el producto no funciona ya que no apaga por completo el foco, se quede prendido muy tenue, con luz casi inperceptible pero de noche se ve claramente que el foco queda prendido, con otra lampara de queso se queda parpadeando todo el tiempo al estar apagada ya configurado.
