    I use Smart Life app for all of my smart switches and outlets. This light switch was immediately found when the power was connected. I don’t know if it’s the light or the app, but I do feel it could be brighter. The installation did give me a bit of trouble as the first switch I had would get power, but not turn on the light. Also, since this is a three way smart switch there are two red wires. I did have to switch them around (once I got a working switch) to get it to work properly. It turned out that the switch was defective, and customer service did try their best to help me figure it out. I ultimately figured it out by replace another treatlife three way from a different room to the location. When I told them this, they immediately sent me a new switch. It works perfectly. I changed all my switches from wemo to treatlife. They are fully integrated with Alexa and work perfectly while wemo never stayed connected. I also have a mesh system! Always an issue with wemo NEVER an issue with treatlife. I will probably need to change my smart plugs to treatlife too!

    The media could not be loaded.

    I bought treatlife products before and love this brand very much, prefer it to other well known brands. This item comes with two switches that could be used independently which is extremely convenient because I wanted to install one to replace a current three way setup in a hallway and wanted to use the other one in a bedroom. I only had to buy this item because it serves both purposes and comes with two switches.

    The switches come with accessories needed to install the, such as instructions, screws and wing nuts. The instructions explain the different setups and were very easy to follow. The back side of the switch has all the wires labelled. After removing the old switch I it was extremely easy to install the new one since I already had a neutral in the junction box. After installation and turning in the electricity, I was able to turn on the light manually before even setting up the switch with the app. The switch displayed a red circle at first so I pressed the switch for about 8 seconds and it started blinking fast. I then logged in to the app and chose the add button and selected dimmer switch. I connected the tablet to 2.4 GHz WiFi and put my tablet close to the switch. It took the app about 30 seconds to detect the switch and set it up automatically. I the changed the name of the switch and was able to use it with google assistant since I already has the smart life app linked to google assistant. And that’s it, setup couldn’t be any easier.

    I highly recommend this switch. I put the rating of the google assistant integration in place of the Alexa integration rating because Amazon does not let us choose between Alexa and google.

    Overall great product. I’ve been having some mobility issues and decided to add Treatlife light switch dimmers, outlet dimmers for my lamps, light switch and ceiling fan combo switch throughout my house. So far, I love it! My friend was able to easily install all the light switches, download the app, and do the complete set-up without any issues. I’ve had the Treatlife products for 6 months and haven’t had any major issues with the app or switches (I have an iPhone). The only issue I do have is sometimes I select a light switch to turn on and a different light will turn on. For example, say I select the “Kitchen” light to turn on, but instead the “Bathroom” light will turn on. It’s a little strange when I have guests over because they freak out wondering why the lights are randomly turning on and off. LOL I haven’t connected it to my Google Nest, so I can’t speak on that. I like how this switch has a routines, timer, countdown, and dimmer settings. That’s been very convenient. The cover plate is really nice. It’s a matte white color and screwless.

    Also, these switches work well with HALO canless recess LED lights. I bought mine at Home Depot. When the lights and switches were first installed there was a strange flickering when they first turned on, but after a few days all the flickering went away on its own.

    Their customer service is great. I bought all the switch at once during a home renovation. My electrician didn’t finish rewiring my kitchen until 5 months after I purchased the switches. I thought it was a long shot, but decided to email the company for a replacement despite their 30 day return/replacement policy. I explained the situation and they gladly sent me a replacement. It arrive quickly and I didn’t have to ship back the other one.
