I have been using the dimmable version of this brand for a while. My LED Pedant lights came without dimming option. I got this switch for 3 way installation and it works very well including Google Home + Alexa. Super happy with the quality.

How to wire in 3 way
I’m writing this to help anyone else who has bought this and struggled with installing it as a 3 way switch. So here goes:The original 3 way will have 3 wires connected and maybe a bare copper ground. One of those wires has a black screw. That’s the common, meaning the switch connects that terminal to one of the other 2 terminals when it switches. In standard wiring, this is either the line power or the load (the light fixture), depending on which of the 2 3-way switches you’re looking at. This switch must be installed on the 3 way switch that has the load connected to the common. You’ll be able to tell which one you’ve got by where the wires are coming from in the electrical box. If all 3 wires are coming from the same bundle, you’re looking at the power side, and it won’t work. If the red and white wires are coming from the same bundle, but the common wire is coming from a different bundle, you’re looking at the load side and that’s where you need to be. At least, that’s how the electrician wired my house.This switch is not a traditional 3 way switch. It uses the other switch as an input to turn the itself on or off. As such, you will only need 2 of the wires from the switch you’re replacing.Connect the red load wire to the common wireConnect the green to groundConnect the white to neutralConnect the black to line powerConnect the blue to one of the other 2 wires from the original switchCap the 3rd wire from the original switchIf you don’t have line power or neutral available:You can open up the other switch box and use the unused wire to run either neutral or power to the box you need it in. Just so that no one in the future gets electrocuted, use red for power or white for neutral and also make sure that the power you connect to is from the same circuit breaker.As for my rating, great switch once it’s installed. Locked off a star for terrible instructions.

Great purchase
Easy to install. Connecting them to the app is very straight forward. The app is very straight forward. I have fitted 10 which is fine but if I fitted 20 or 30 I would want to group by area and this one cannot do. They have been up for a couple of weeks and so far no performance issues. They look fine.

Scary! A house that talks to you?
My younger neighbor always brags about his SmartHouse & how Alexa & Google are trained to meet his demands. So he insists I make my house smart too! These light switches have blended gently into our lives w Google & Alexa!
