Product Description

The Smart Light Dimmer Switch adds smart bulb functionality to traditional bulbs and keeps LED smart light bulbs smart so that you can dim any room with any dimmable bulb. The smart WiFi switch works as a dimmable light switch while enhancing the traditional bulb functionality to include out-of-home control, scheduling, and scene-setting. When CYNC Smart LED Bulbs are installed, the dimmable switch allows app or voice control even when power is turned off at the switch. Pair the dimmable light switch with CYNC Smart Bulbs in other fixtures like table lamps and control all your lights in the room from one wall switch. Our smart dimmer switch wirelessly connects with other CYNC Smart Light Switches so you can control the same light fixture from multiple switches. The smart dimmer switch also allows for single-pole, 3-way, or 4-way installation with other Cync smart switches. Install the smart switches on your own with easy, DIY setup or with the help of a professional in newer homes built after 1980 using 2.4GHz WiFi. The smart light switch connects directly with Amazon Alexa and Google Home devices without a hub required. Neutral wire--usually a white or gray wire--is required.

    EXACTLY what you need if your wall switch controls the "wrong outlet" in your home!
    5 Stars
    EXACTLY what you need if your wall switch controls the "wrong outlet" in your home!
    We just bought a new home and if you are like me, this product is EXACTLY what you need!In our living room the 2 wall switches both controlled 1 outlet. UNFORTUNATELY though, this outlet is where we placed our entertainment center (TV, Soundbar, PlayStation, Wii, etc). So shutting this switch off would turn ALL that equipment off! If you have a PlayStation you know what happens when you kill the power to it (hard drive inspection, possible data damage, etc). So this would NOT work!I was NOT rewiring our house and tearing out drywall to fix this so that the switches would instead control lamps in the room.Enter the Cync "wire free switch" and "Cync Smart Plugs".With the wire free switch you can control a myriad of different Cync items. From directly controlling individual light bulbs (dimness, color, and on/off) to controlling the smart plugs.The BEST part about these is the way they can mount! Not only can you stick them to ANYTHING via the double adhesive tape included with the kit but they also CAN mount into a standard wall box! Both mount options look great and even using the tape you can't tell that the switch was just stuck there. However, for my application I used the wall box mounting. Allowing me to get rid of the switches that killed my entertainment center!! After bypassing the wiring for the switch (so outlet ALWAYS has power) I removed the old switches and pitched them in the round file (trash). I then used the old screws from the switches to mount them right into the box where those old switches were.I also purchased the "smart plugs" to use with lamps that are on the other side of the room! This allows you to setup your switches and plugs any way you like! Both switches can control both plugs if you want, but we set it up so that each switch controls a different lamp in the room. The app is great and works with Google and Alexa. We have Google "home" smart puck things. Just tell Google to turn on or shut off the "lights" which will do them both or call them by the names you set up in the Cync App to control them individually. We call one "living room light" and the other "living room door light".The ONLY ISSUES we had was setting up the multiple plugs with Cync on my Samsung S9. They seem to be having an issue with WiFi connection setup of the plugs with Android.I WILL give their customer service the ABSOLUTELY HIGHEST praise I can EVER give ANY customer support though. They were absolutely amazing! They helped us through everything and even messaged me out of the blue when they hadn't heard from me in 2 days (because I was busy with the move to the new house). How many times have you had customer support contact YOU to see if everything worked out ok or if you were still having issues?!?I WILL say if you are having issues with the plugs that what we did was... Set up the new plug in a NEW room rather then trying to add it to an existing one. We also had to use my wife's iPhone to set it up. It also DID fail when trying to add it to the same room as the other plug! However, you CAN move items around after setup. So we added it the a NEW room with the iphone which DID work. Then I moved everything around and renamed it with my phone.I DON'T discredit them for this issue AT ALL because it did work and they ARE working on trying to figure out exactly WHAT the bug is with the Android version. Plus their customer support is SO amazing that it makes up for any little issues, especially since they are resolved!I am actually about to purchase more switches as well to use on the ceiling fan in my son's room. The fan is hard wired and the lights on it and fan/speed can ONLY be controlled via the pull cords. His switch ALSO activates the dang plug where we put HIS tv, and playstation!!To solve this in his room I will be buying the Cync Smart bulbs and replacing his wall switch with one of these wire free switches! Then connecting that switch to control all 3 bulbs in his fan simultaneously. I will probably get him the cool color changing ones too. Since this switch can do that as well! Even if you don't use that feature... For some reason this switch is cheaper then the "basic" version that only does on/off.Hope this helped someone because I couldn't find out EXACTLY if this switch could or couldn't do what I needed it to. Now knowing it can I figured I'd share the results!
