TREATLIFE 3 Way Smart Switch 4 Pack, 2.4GHz WiFi Smart Light Switch 3 Way, Works with Alexa, Google Home and SmartThings, Remote Control, FCC, Schedule, Neutral Wire Required

Previous Treatlife switches work so well that when a different brand switch failed, I ordered these 3-way switches

They work great, except they're a bit large considering the size of the 3-way cables. You just need a lot of patience and care during installation, as you'll need all 5 cables to connect. The click when it turns on and off is very soft, and it has a small light that tells you whether it's on or off (which you can turn off via the app). It's very easy to set up for Wi-Fi in just a few minutes.

EXCELENTE

Just installed 12 switches (4-three way, and 8 single pole) and overall I am pleased, but there are a few things to point out: As others have mentioned, these are only 2.4 gHz WiFi, so the hardest part of the entire install was trying to come up with a way to get my router and phone on the same page to only use 2.4 during the setup since I can't turn off the 5 gHz radio on my home router (finally worked when I stopped broadcasting the 5 gHz network ID and turned the radio power down to 25% which is the lowest it will go). Other than that, on the smartlife app on Android, when syncing with a new switch you tell it that it is a WiFi switch, put in the Network info and password, and then you get to the screen where it wants you to confirm that the indicator light is flashing rapidly and the button is grayed out. I pushed the switch button for several seconds as outlined in the instructions, the indicator light started flashing rapidly, and nothing happened as far as the button switching over to something I could push. After several attempts, I started tapping the screen in frustration and that was when the line of text just above the button had a radio button that changed state when I accidentally tapped it (it is not obvious that it is a button to push), and then the button to proceed switched over to where I could sync things up and everything from there out was really easy. Renamed the switch, linked up the Smartlife App in with my Google Home, added the unassigned switches to rooms and things worked exactly as you would expect. I am a tech guy, so going into the advanced admin settings on my Orbi router is no big deal for me to work the issue, but if you are not the sort of person who can be trusted in the settings of your home network, and you don't have an easy way to isolate things to just 2.4 gHz during the setup, you might want to get some help or find a different option for you.

UPDATED: I contacted the company by email through Amazon. They replied and told me to use the SmartLife app. I did, and it worked. Their programmers ultimately fixed the TreatLife app, too. They said we can use either the SmartLife or the TreatLife app.---------------------------I have many Treatlife switches and devices. Everything connected with Alexa until recently. All of a sudden, nothing from Treatlife works with Alexa. I have disabled and re-enabled the Skill, but nothing seems to make these products work with Alexa again. The Treatlife app still controls the products, but will not connect to Alexa. If the products do not work with Alexa, they are worthless to me and will be replaced. Treatlife has received many 1-star reviews on your Alexa Skill page (https://www.amazon.com/gp/product/B08HWJT1WD?nodl=0), but they have not responded to any of them. Until the Skill is fixed, allowing these switches to connect to Alexa, do not buy them!

The initial installation was a bit of a challenge...first, the app developers thought that small font gray text on a white background would be readable. It is not. I bought both the single-pole and the 3-way switches. Once they were set up, they worked with both my Echos and Google Home, once accounts were linked. The voice control was very convenient. But with this product, once you finally get things set up, the device may go offline. When this happens, it is almost impossible to get the switch to go back online. There is no simple reset button...you can press the switch until the lights start flashing, but the app will not connect to it. It does not broadcast a network ID, so you cannot connect to it directly using its wifi hotspot capabilities. It basically functions as an expensive dumb switch at that point.The single-pole switches get set up in the SmartLife app, and the 3-way switches get set up in the TreatLife app. Technical support is useless...I was asked to find the box that the switches came in. To access any information or identifying features of the switch requires removing the switch. Having multiple smart switches on the same breaker means that when trying to troubleshoot one switch, you end up creating problems for all of the other switches on the same breaker. It is just incredibly frustrating.I've had a variety of smart lights, switches, and outlets. This is by far the most frustrating to deal with (well, other than my GE smart bulbs, which just stopped connecting to my network). Of all of the products that I have tried, I have to admit that Philips Hue lights are the easiest to set up and the most reliable to use. I have had zero problems with those lights after many years of use. Yes, they are more expensive. But at this point, I would rather pay a little more money to have smart devices that connect to my network easily and work flawlessly over the years.The bottom line: I definitely do not recommend these switches, even if they go on sale during the holidays. The user experience for the app is terrible if you have less than perfect vision. If you do manage to get them connected to your network, if they happen to go offline for any reason (power outage, shutting off power to the breaker to install a second switch, etc...) it will be next to impossible to get them back online. Spend a little more and go with Philips or Belkin (WeMo). Or just stick with a traditional rocker switch...it will give you less grief. To be fair, the single-pole switch that I set up first has continued to work (that setup involved using the Smart Life app, not the TreatLife app). But, once bit, twice shy, especially since I've also run into a similar problem with the Smart Life light bulbs (same company, different name? Out of the 4-pack that I purchased, I'm down to one bulb that is functional, so it's not a great return on my investment). Once they go offline, they don't want to connect with a network.UPDATE: after being contacted by the company, I am even more frustrated. Their advice is to just go through the set up process again. Of course, since the switch isn't able to pair with a device, this advice is not only useless, but it is irritating. I am being reminded that my switch doesn't work as intended. My option at this point is to either use it as a dumb switch (the ones you can buy for $1) or remove it (involving turning off power to ALL of my devices on that line, and risking screwing up others that are already set up and working) and replace it with a dumb switch. So, I can at least control my light with this dumb switch. I would give this product 0 stars if I could.
