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.

It took a while to connect, which caused me to have to watch a YouTube video to make sure I had done everything correctly. (I had.) So far, so great!

Ich habe mir diese tolle Uhr in der Farbe lila bestellt. Was soll ich sagen ? Also davon mal abgesehen das sie vom Preis einfach unschlagbar ist , dazu noch mega gut aussieht , hat sie alle Funktionen die man für eine Smart-Watch brauch. Sie hat 12 verschieden Sportmodule wobei jedes einzelne super funktioniert,sie überwacht den Schlaf und selbst Nachrichten die aufs Handy kommen , kommen bei ihr an. Und sie kann noch so so viel mehr. Also man brauch definitiv keine Uhr für mehrere hundert Euro kaufen , diese hier ist einfach super

This is my 7th Treatlife smart switch and I'm so happy with it. The installation instructions and videos are so easy to understand and make it so simple to follow. The back of the light switch is labeled with line, load, neutral and ground. Connecting to Google Assistant is a breeze. I just can't say enough about these switches.

One year ago I tried 4 smart locks and I didn't like them, so I returned all of them.This year, I decided to give this one a try. I love this smart lock - warning: requires some skills to install it - fingerprint recognition is good. Actually, I have never used the other opening methods because fingerprint recognition is the easiest way to go.I'd buy it again.

These Kasa Smart Dimmer Switches are the beginning of our smart home. They are very easy to install and the app walks you thru each step. The app also can help troubleshoot if needed. I did need help with just one of the switches. It would not connect, turned out it my phone had switched networks. But the app figured it out! They work seamlessly with Alexa or Google Home. I use both products. Kasa products store the setup configuration on each device which makes router swaps or a network issue easy to recover from! The switch dim very predictably and smoothly. Each switch has a multi-colored LED to indicate it's status. I am so excited to be building out my smart home and using TP-Link's Kasa Smart Dimmer Switches!

Had to buy the actual apple brand connector so I could watch my subscriptions and it works great so far! The sound could be just a tiny bit louder, but it works!

I've never worn a fit bit or smart watch before. I don't even wear a regular watch. But after my heart attack, I wanted to monitor my health better. Amazon sent me this watch for review so I thought I would give it a try.First of all, it is heavier than I expected. And I do not like the silicon watch band. I'm going to go in the fossil web site and order a different band. The silicon band makes my wrist sweat and the watch keeps slipping on my wrist.I opened the box and it comes with a mini book in print so small and in numerous languages on safety regs. Then there's a little piece of paper that's your intro to a quick start. That's it. I couldn't figure out how to use the damn thing till a friend told me to download the app. Even the app isn't much help but it did set up the phone pretty quick.I like the sleep monitor function of the watch. It really made me aware of how trashy my sleep was. I've been working on it. I also use the heart monitor and oxygen function regularly. But the problem with the displays is they are so small they are hard to read. I don't even bother trying to read my email or the other stuff posted. I can't see it. I would like to get my texts on there but can't figure it out how to set it up. The weather function works great. The Alexa function doesn't work- it's on there but says not available yet.I did change my watch face to the cute puppy that happens to look like my fur baby. The numerous faces you can have is fun.The battery doesn't last but a day or two before needing recharging. So I can either wear it during the day and not at night so it can charge or vica versa. That's not handy. It doesn't do a good job tracking my steps.I'm not sure it's worth the money but it did offer some neat functions. Just wish I knew how to use it more.
