I had been in the market for a Wi-Fi enabled dimmer to control 6 recessed lights in my family room for several months and was excited to see that the Wemo Dimmer announced earlier in the year at CES 2017 was finally becoming available. I had also recently purchased an Amazon Echo, so wanted to combine the voice control capabilities Alexa provides as an added plus.

The unboxing was exciting and it seemed more like a smart phone channeling Apple with the minimalist packaging and polished aluminum back to the device (plus 1). The instructions were pretty straightforward and having changed out other switches in my home over the years I felt comfortable doing so. The instructions even led you through what to do if you need to swap the hot and load lines which (even though there is a 50% change of getting it right the first time) always seem to get reversed (plus 1).

After installation and confirming that the switch in fact did control the lights, my next step was to connect it up to my Wi-Fi using the Wemo app on my iPhone. This is were things started to get more complex. Having just configured my Echo using a similar approach, I was familiar with how to attach to the Wemo device from the Wi-Fi control panel and then open the app to finish the configuration. This is where I got stuck with either the app crashing part way through the process or the app being unable to connect to the Wemo. Tried many different approaches (power cycling the switch, restarting the app, etc.). I was finally able to get it to work by trying from another device, but this too required several attempts (minus 1).

Finally, I was able to get the app configured and then was able to set the bulb type and dimmer range. This is where I had my biggest disappointment with the product. About six months ago I had converted the incandescent cans into LED fixtures and had no problem controlling the dimming using my previous analog dimmer switch. Was able to dim to I would estimate around 10% of full brightness with an analog switch. The Wemo Dimmer gives you the capability to configure the type of bulb (LED, CFL, or incandescent) in the app and then adjust the minimum and maximum brightness to ensure you have smooth dimming with no annoying flashing. Unfortunately, I was only able to get Wemo to dim my lights to around 50% of their full brightness before they would strobe/flash. This seemed like pretty poor dimming performance compared to my previous analog switch (minus 2).

Overall, I love the Alexa integration but was frankly disappointed by the performance of the dimmer. At the time I looked, this seemed to be the only dimmer product that was Wi-Fi enabled with Alexa, so will stick with it for now, but really only have "bright" and "brightest" for my end range of controllable light levels.

We've graduated to the tech age, lol. Our daughter bought us an Amazon Alexa and we've gone crazy turning our home into a Smart home. We have these on every lamp in the house. The Wemo App is pretty easy to set up and then you just have to add it to your Alexa App and the Wemo App allows us to customize it tons of different ways. No more whirring red pin/green pin lamp timers, these do it all and are completely silent. You can customize on and off times and these can be overridden by Alexa voice commands so if the lamp is set to auto shut off at 11:00 PM I can simply tell Alexa to turn it back on if I'm still up doing things. We have even added Wemo light switches to a few of our lights and now have Echos throughout the house to voice control or autoset those lights to come on and turn off at specific times as well. We are having so much fun!

We've been waiting for a wemo dimmer to be released for a while now. We have four other wemo devices in the house and have never had a single issue with them. This one is a bit different, though.

Installation was a breeze, and we got it added to our wemo account within minutes of installing it. The only issue was that it didn't show up on our iPads (wemo iPhone app) for several days, while it was listed on our iPhones almost immediately. Eventually it showed up on our iPads, so I'm glad that's not an issue anymore.

The other issue is I can't figure out how to best control the capacitive touch slider. If I tap on the brightness level dot that I want, nothing happens. If I slide my finger up and down the brightness level indicator, usually nothing happens. Sometimes it will work, and sometimes it won't. Thankfully using the iOS app is pretty reliable, so I usually set the dimming level through that.

Good first attempt Belkin, but please create a Universal iPhone and iPad app for wemo, and please fix the capacitive touch slider.

I really, really wanted to like this product & technology, but the failure modes and failure rates are astoundingly high.
Relevant background to my skill levels:
I bought a couple of the plugs so that I could experiment with how to automate my home. I am neither a software or hardware engineer, however I am a (very highly) qualified engineer and I have self taught myself a lot about network hardware & application of software packages. I have an advanced router with repeater, fully LAN & WAN connected house, with network switches, POE devices etc. that I installed & runs pretty cleanly.

First of all the app - I am still on 2nd level support waiting for a response to an issue where I am patient zero. I can create a rule, but it does not give me the choice of days. It is the same rule every day or no rule at all. I have tried installing the app on 2 i devices, same issue(the even have different itunes accounts to further firewall them from each other) So the app is highly buggy. App version 1.17.1.

2nd, the switch(es) I have RMA'ed one of my 2 as I still could, the first one I am stuck with. The 2nd one experienced worse functionality issues than the first one. It had to go as this is a defective unit.
The rules limited me, so I tried anyway.
Initial first time setup was quite smooth & I was initially impressed. (Hadn't realized the rules issues yet)
Paired it to Alexa, that was pretty smooth too (Still impressed)
Ran it for a few days, had fun having Alexa switch it on & off etc.
Then we had a power outage. Big system failure on the WEMO.

After restarting power, everything else came back up properly.
I tried restarting the first switch (the still semi functional one that is not RMA'ed) several times to see if it would boot up, it actually would not boot up until I had pushed the power button several times & actually physically unplugged & replugged it several times.
The WEMO devices were not recognized by the app on my phone, until I switched it to the same wifi network as they were running on. This i snot helpful when you are trying to make a remote access switch.
So after trying & rebooting I have given up.
I cannot set up a smart house with devices that require a full factory reboot and me to delete the app, reset all rules from scratch, every time the power fails or blips.

So sadly I have to say the devices are junk, the app is junk and they need to be fully redesigned before both parts of the system become stable & reliable.

Sorry Belkin, but you also have a lot of people on your own Community pages with many similar problems & your own support is not the one finding solutions, it is other users who have more time to do this than most of the rest of us have.
So, folks, if you read this far, don't waste your time & money, these devices are great in concept, but are far from Implementation Ready for mainstream use.

I have never been paid to write a review - good or bad and I have never been given anything for a review, except for one thing that was sent to me that I didn't want & I contacted the vendor & asked for an RMA (They said donate it - so I did). What you read is my genuine experience.
Sadly 1 star reviews get pushed out of sight on Amazon & they are hard to access (even your own ones).
Thanks for your time.

Updated 3/17 to add rules screenshot showing the app issue with no days selectable. App version 1.17.1 (420001) that I am trying to deal with on 2nd level support. I still struggle with the concept that I am the only person with this issue & that it is identical on 2 unrelated Apple devices that are on different accounts.
Just a side note - when Customers are on the phone with your reps, when discussing the product, it really makes a better impression of your company when they are aware of who your major competitor(s) are. 1st level support had never even heard of TP Link (check the recording it you don't believe me).

3/30/2017 update.
I found a workaround out of sheer frustration & anger &, well, it is still strange.

I had a blank screen for the days selection when creating rules. Nothing showed up at all, ever, I have deleted & reinstalled the app 3 times, done a full hardware reset on the switches 3+ times, had Belkin 2nd level support on the phone - you name it. (That was a whole different story - see the response comments!)

So I was giving it one last try to see if it would work, I reinstalled everything from scratch.
Set up a new rule - still nothing snowing in the days area of the screen.

So I was really very angry about how much time & energy I had spent on this whole exercise & I was absentmindedly tapping my phone screen repeatedly, when I suddenly noticed that it was highlighting days of the week.

So I played around some more.

I can get it to highlight, at most, 6 of 7 days, in any combination.

I have to guess where the day is to be selected on the screen, then I can find it.

I sometimes have to tap that spot several times to get the day to select (no it is not my touchscreen, both devices have the same response)

What I then found out was, if I select a day & I can now see it, that means that day is one in which the rule will NOT work. It Will work on the days that are not selected & still invisible on the screen.

I have attached a couple of random screen shots so you can see what is going on.

Is the issue fixed - no, not at all, it is still there & the software still has a huge flaw.
Does it work enough that I want to continue to try to experiment with it - yes
Will I want to see a software update to fix this issue - yes
Do I want to continue to use this switch for the short term - yes
So in short, I will not send it back, yet. There is something going on.

I tried this workaround on 2 different Apple products (Iphone 6 & Ipad Mini 3) and the workaround works on both.

Is it still fatally flawed - yes.

Please can you pass this on to your 2nd or even higher level Engineers as there is still a problem that must get fixed, but this is a partial workaround.

By the way, I also tried changing the screen color settings to see if it was screen contrast or color related - no it is not, the Apple devices are working exactly as they should, it is your software with the bug.

If you want me to try anything else, have your engineers get in touch & we can see what we can do.

I have still lost significant confidence in the product & am very unsure if I want to invest in any more of them to automate other parts of my home at this time.

I purchased 4 mini plugs. Started to install them in an environment that has two wireless routers linked together. The first went in just as expected..I took the second to our bedroom but it would not connect.
I called customer support and they were of little help. Language barrier. Being somewhat knowledgeable about networks I took the second unit to the same plug where I attached the first. It loaded up quick and correctly.
I then took unit 2 back to the bedroom and it continues to work, then after looking at app and lack of documentation on details I noted a small switch that says use same setup as previous units. This works fine unless you have multi routers then you have to turn this switch off so you can pick a different router
I plan on expanding my WeMo system through the house. The app is very good and simple Love the link from amazon-echo.. can even use the amazon remote to turn light on and off. One question. Can I get this to work on my wife
