TREATLIFE Smart Light Switch Single Pole Works with Alexa, Google Home and SmartThings, 2.4GHz WiFi Timer Smart Switch, Neutral Wire Required, No Hub Required, FCC Listed, 4 Pack

I've bought and installed a good number of different smart switches. This is an excellent switch, especially considering the price, and will be my new go-to if I ever need more.Install:Installation is just connecting the 4 wires coming off the switch to 4 wires behind your current switch.Install is easy if you have enough space to fit the new switch in the gang box behind the switch plate, and it has both a neutral and ground wire. (Some switches only have 2 wires behind them, line and load. You cannot use this switch.)There are 4 wires leading out of the switch and included twist connectors; I found installing these a fair bit easier than switches which have screw terminals and the connections feel more secure (I hate twisting wire around screw terminals).Your existing switch might not have line (the cable which always has power) and load (the cable that goes to the fixture and has its power toggled by the switch) wires labeled -- or labeled incorrectly -- since with most conventional switches it doesn't matter. For this switch, you need to make sure you connect them to the proper load and line wires or the device won't power on. So if your device seems dead, try swapping your line and load connections (you won't have hurt anything with them having been backwards for a little bit).The device will also not power up if the neutral line isn't connected. If your device doesn't power up, make sure that's connected properly.Connecting:All 8 switches I set up paired without problem. Hold the button down until it starts flashing, and the app finds it quickly and adds it to the app.Voice assistants and remote control:These switches connect to both Alexa and Google Home. Both have been working perfectly and respond quickly and consistently. (Since these are controlled on the cloud, I was worried latency could be an issue but it wasn't with these.)Local control:I'm not taking a point off or anything because this wasn't a listed supported feature, but I really, really wish these switches offered better local (ie, non-cloud) access and control. As a home automation geek I use Home Assistant to control my home's smarts, which runs on a little Raspberry Pi computer. Having the ability to control these without the cloud would be awesome, but isn't possible anymore due to a recent firmware version. That's a huge shame because there's a decent chunk of hobbyists like me who really appreciate non-cloud control (it's faster and more reliable). If any of the company reads this and can figure out something here, you could get a decent chunk of passionate users :)All that said... I'm still really happy because the cloud functionality has been working flawlessly and with no noticeable latency. I guess it's not a big deal if I can't control my lights if my power is out huh

The media could not be loaded. These switches are super nice. I started with the two pack to automate my kitchen and garage lights. It was so easy to install because it came with eveything needed to complete the job. The integration with the Smart Life app was easy and Alexa figured it out automatically. After becoming more familiar with smart home products and they're voice command capabilities I made the switch to google everything. Using the Google Home app on my phone I was hooked. The google mini hub was my next purchase which makes the use of voice commands even easier since I have a screen lock on my phone (you can't use google assistant when your screens locked). I bought a 3-way switch next to control my hallway lights. I love that only one of the two switches needed to be changed. I installed another 3 way in my bathroom and also at my brothers house. These switches work so well and look so nice that I have recommended them to my co-workers and my patients as well. I bought this four pack so I could automate the front entry/patio, back patio, and side door. I recommend getting some lever wire nuts instead of using the nuts that come with these switches. They will make your install go faster and you can rest assure no wires will get loose during the install. After months of use I have never had a single issue with any of my Treatlife switches. I have only seen a few negative reviews about their products and I always feel compelled to respond to them because its seems to be due to their poor installation or an outdated Wi-Fi router. This review is completely honest and I'm not paid or compensated for it. I work as an ambassador at a well known foundation hospital in Southern California. These products have helped so many of my patients with disablities have a better life using home automation. My next purchase is going to be the dimmer switch. I think that it's going to be a game changer for my bedroom light.
