TREATLIFESmart 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

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!

I've been putting off installing smart switches, unable to justify the cost of installing so many around the house, and concerned the cheaper options wouldn't cut it. I finally pulled the trigger on these, and couldn't be happier. They're simple to install (about 15min per switch, once you know what you're doing), the Smart Life app is responsive and reliable, and with a bit of futzing, you can fully integrate with Smart Things, Alexa, etc. I'll comment on a few concerns I had going in, based on other comments I'd seen before purchasing:Potential Concern 1: The device is too deep to fit well into the box. I didn't have any trouble. I've installed two into a 2-gang no problem. My house was built late 70s, then extensively renovated in the early 00s, so I've a mix a shallow, 40 year old boxes and deep newer boxes. The shallow boxes were a bit of a puzzle to get the wires folded in well, but I got them all.Potential Concern 2: Wifi based switches are less reliable, power outages cause issues reconnecting, etc, etc. I have only had these installed for 3 weeks, but haven't had any trouble. Note that I've repeated caused "power outages" by throwing the break switch while installing other switches, and they've always immediately reconnected. In the most extreme case, I installed a switch, then a week later replaced it with a smart dimmer from the same company and left the original switch on my work bench, then a week later installed it somewhere else--smart life immediately recognized the switch and everything was fine (though of course I then renamed it). If it can handled a 1 week power outage, I'm sure it will be fine for any real world scenario.Potential concern 3: Wifi based switches have too much lag. I don't have any trouble with this. I have numerous automations in which once switch flips on many others (how annoying is it to always flip the same 5 switches when you walk into the kitchen? Problem solved!). There's essentially no lag, provided your internet is reliable.Potential concern 4: Limited interop with Smart Things and Alexa. I do like the Smart Things app better, and I have some smart devices (notably, a Door Lock) that don't work with Smart Life. But the internet is full of wonderful hacks. I followed one in which I set up a virtual switch in Smart Things, then used ifttt to have Smart Life switches flip the Smart Things virtual switch. That Virtual Switch implements the contact sensor APIs, and so can trigger Alexa, the door lock, whatever. It's a bit annoying to set up, but provides infinite interop between Smart Things, Smart Life and Alexa, which covers just about everything. The main issue here is that ifttt has significant latency, so this only works for links that can tolerate substantial lag.Two Annoying Things:1) The switch doesn't implement the contact sensor API Alexa uses. So you can't trigger Alexa routines when you flip a switch. The ifttt/Smart Things Virtual Switch hack fixes this, but adds considerable latency and it's annoying to have to do that.2) Smart Life has a limit to the number of automations you can have. I've no idea why, couldn't find documentation of what that limit is, and it was annoying when I hit it. Also, the Smart Life app has some questionable UI choices that make it a pain at times to work with (at least on iOS).A final note: These are single pole switches, which means they're not intended to replace 3 way switches. BUT, if you understand how 3 way switches are wired, you can hack two of these to serve as a three-way (or arbitrary-way) switch. The trick is to make sure both switches have a constant power source (ie, the Line). Often, one of the three way switches doesn't have that, but you can use the Traveler to run power to the switch that lacks the line. Then chose one switch to be connected to the light via it's Load, and cap the other switch's Load. Finally, use Smart Life to link the switches together. I used a similar hack to change a three-way switch in my kitchen so that the switch by the door to the garage acts as a master switch that turns on all kitchen and dining lights. As a matter of cost, this is significantly cheaper than buying two 3-way switches, but more expensive than using a single smart three-way switch and leaving the other dumb.

Installed the smart switch and they were easy to do. I can control them via my Alexa.

Cant get to set it up with my phone

The media could not be loaded. As perhaps many of you out there, I really appreciate a detailed review of products I find interesting on Amazon but unsure of the manufacturer or vendor, and I rely on such reviews to influence my purchasing decision. Sometimes, the price of the product is reasonable enough that I'm willing to take a chance on it regardless of the review. In this case, it was a little more of the latter since on BF2019 I was able to purchase a 4-pack of these Treatlife wifi switches for less than the cost of a single switch my friend paid for a name brand based on Z-wave technology that required a separate hub at additional cost a couple years ago. After installing these switches, my initial impression is very positive, and counters some of the concerns expressed in the reviews I had read while making my purchasing decision; I won't mention any by name, but these were some of the issues that had concerned me the most from the reviews...Concern 1: Yes, these switches are a little deep, but fortunately the electrical boxes in my home are sufficiently deep enough to accept the switches. I especially found my multiple-gang boxes to be more accommodating, since I had only modified one of the switches with the Treatlife, and was able to neatly tuck most of the conductors and wire nuts behind the other standard switches. It also helps to employ some wiring space-saving techniques such as eliminating excess wire length, folding wires accordian-style, and tying a single hot wire across all your switches in a multi-gang box. For extra safety in a crammed box and to prevent shorting, make sure to tape up your wire-nuts and screw terminals on the other switches in yourbox (a shortcut I find too many installations skip out on).Concern 2: Yes, these Treatlifes are all-plastic switches, and so the mounting tabs are a bit thicker than the stamped metal for standard switches. When I first installed the Treatlife switch, I noticed the thick tab would create a gap between my switch plate and the wall. However, the quick fix to this was simply to take a utility knife and/or side-cutters to trim down the small plastic boss on my switch plate that screws onto the Treatlife switch (see marked up photo). After trimming the boss, the switch plate looks great flush against my wall.Concern 3: Bright LED indicator on switch. I didn't find this to be the case at all for the switches I installed. They are certainly no brighter than any of the other LEDs on the devices in my bedroom and I find them actually to be a feature that enables me to see the switches better in the dark (although that really isn't an issue anymore since my lights are now voice activated!)Concern 4: Need to reprogram whenever the power goes out. Okay, I found this posted concern to be legitimate, and I wonder how many others have experienced this issue? I wasn't sure if it was my modem or router, but whenever I was shutting down circuit breakers to work on installing the next Treatlifes switch, my Alexa devices would no longer recognize the switch and I would have to reprogram through the app. However, I have four different brands of smart switches or plugs in my home, and I have similar issues with all of them except for my Amazon-branded smart plugs. I was also wondering if it was an issue with Alexa, however I also have some Google Home Minis that do not recogize the off-branded smart switches/plugs when the power is cut as well.The other issue/concern I have that I'm not sure I've seen posted is whether these Treatlife switches might overheat since they are packed in a rather tight electrical box. I haven't noticed them getting hot so far, and so I hope this is an unwarranted concern.Overall, I am very happy with these switches, and I would recommend others to give them a try, especially if you can catch them on a deal.

I have many of these switches around my house already. Love these devices. They're dependable and high quality. Definitely recommended. I went with this brand because they were the only brand that had a smart variable fan speed switch too.

Easy to install, work well with the app on the phone.

Great value
