A great Alexa compatible switch for 3-way circuits
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.

This switch requires a 2.4 gHz WiFi connection
Great product!I bought the Moes Smart WiFi switch because the circuit that it is on does not have a neutral wire. The good news: the Moes Switch doesn’t require a neutral. This brings up a quirk: you must wait about 10 minutes from power up before the switch is operational. The instructions say 5~7 minutes. Mine took about 10 minutes. A bit hard to say exactly, since I was going back and forth from the breaker panel in the basement and upstairs.The next challenge was that the Moes WiFi switch requires 2.4 gHz WiFi. I have Google Home and use Google Nest Mesh WiFi. Google Nest can’t be forced into 2.4 gHz, it cycles between 2.4 and 5gHz. This isn’t a very convenient or user friendly option, but it is what it is. I ended up installing a TP-LINK WiFi AP that works exclusively on the 2.4 gHz band.Things you should know:- The Moes Switch works without neutral wire.- There is a gap of about 10 minutes from the time of power up until the switch will work.- Requires 2.4 gHz WiFi- Pressing the power switch for 5 seconds performs a resetAdmittedly this wasn’t Plug and Play, but it works admirably in a challenging installation. I haven’t seen any other product that could do as well. Go for it!

Very easy to install
Very easy to install and setup. User friendly app controls. One of the easiest WiFi switches I’ve ever used.
