Wemo Smart Dimmer Light Switch with Thread – Smart Switch for Apple HomeKit – Smart Dimmer Switch – Smart Light Switch Dimmer – Smart Home Switches – HomeKit Light Switch – Neutral Wire Not Required

worked reliably on thread, it is full thread device and extends your network, no flickering
So far it has been good, haven’t dropped off at all from my apple homekit/thread network and everytime my homepod goes off or was power outage, it reconnected super quickly! (I think there was a firmware update when I initially installed it, make sure you do it), the setup via matter code was super easy, installation isnt’ the best experience as these smart swithes are bulky and hard to get into the wall, but not terrible tbh, and I don’t like slow wifi smart switches that can overwhelm your wifi in the house, there is genuinly faster response with thread network and it is noticable especially if you plan to setup automations such as contact sensor door opening triggering the lights.Another important factor is flickering as dimmers for LEDs effectively need to oscillate the electricity at high speed off and on (with more “off” than “on” to dim), and if they are not well designed, they will flicker, or at lower dim values the light will flicker (this also kinda depends on your light bulbs too, so make sure you get decent quality one) I bought the best rated ones in Amazon with this switch and so far it has been super reliable, I also like that it is well tuned (between 0% to 100%) vs Kasa or few other dimmers that basically max out at 50-60% and even after tuning via Kasa app they are not well tuned and don’t transition smoothly from 0-100%.It is just a bit expensive, but good quality and looks great and is thread!

Pricey, but really great switch!
I am usually an Elgato Eve buyer but since (as of 01/2023) they do not sell a proper dimmer switch in the US, I decided to look at the Wemo option.I also wanted a switch with thread as I have the latest Apple TV & HomePod Mini as well as a couple other thread accessories so it would join a reliable mesh. Note that although this switch has THREAD it probably will never be part of the MATTER standard. Since I’m pretty much exclusively an Apple HomeKit user this didn’t really mean anything to me since this already integrates well with HomeKit.All of that out of the way, I found this switch to be fantastic! It was very easy to install (although, like pretty much all smart switches it is very fat and sort of has to be crammed into most junction boxes which is a bit annoying, but that’s not exclusive to this switch). It performs lightning quick! Far, far more responsive than the older non-thread Bluetooth smart switches that I have. Adding to HomeKit was seamless and easy. I just installed it recently, so I can’t comment on any potential intermittent disconnection problems that may arise but again with this being thread compatible I don’t expect it to be a big issue in my experience.Some users complained about the wiring install. I agree that wrapping the wires around the screws would be very difficult, but for me plugging directly into the back worked perfectly and was fairly easy. My home was built in 2020 so was built to the latest building codes (included neutral wire etc) so YMMV, but I really don’t see how this switch is any different from others. If you have never installed these sorts of things before, I also highly recommend buying a “wiggy” or some sort of non contact electrical meter so that you can easily identify the load vs line wires.Now the only negative. At the current price of $55-60, I do find that to be just a bit too high for what it is. I anticipate this will fall over time to $45-50 which is a little more fair, but at these price levels I think you should only buy this is you are a really big techie like me. If you’re more casual or just looking for a great smart dimmer switch, I would look at cheaper options.Overall A+! Very happy!

Wiring may be an issue. Left power switch will not stay seated
The push in connectors are not the traditional lock in like most major brands. The wires can be easily pulled out of place as the screws just can not tighten enough within the clamps. The only alternative would be to wrap the wire around the screw itself but that in itself can be a challenge. Ended up returning after the second replacement thinking the first was defective. Left power tab won’t stay depressed and as a result the circuit can never be closed. Very bad product design. The goal was to replace all the older models that have been blinking red since demo decided to shift to a cloud environment and did not give the option to disable the red lights. It looks like the upcoming Eve switches will be my only option.

Wemo quality and reliability. One thing that should be made a little clearer is that this generation of switch is not controllable with the Wemo app.

I have to power cycle this thing once a month otherwise it looses its connection randomly. I’ve had much better luck with the Eve smart switches.
