This is the first Matter smart device I purchased. I have purchased and use wifi, zigbee and z-wave devices and now I wanted to test out this Kasa Smart Dimmer Matter switch. Packaging was nice, less packing material compared to their other smart devices, so a plus for the environment. Comes with wire nuts, screws, face plate attached, instructions and a qr code sticker for the device. On the switch itself is the MAC number of the device and the QR code number to enter manually. The switch has only two pigtail wires and they are for common and ground. The load and line wires are screwed into terminals. I would have liked the option to have a ground screw terminal also. Less wires in the outlet box makes for an easier installation.
Speaking of installation, that was simple and straight forward. Turn off you power at the breaker, test the line an install like a pro. Took me about 5 minutes to install, was going for record, just wanted to make sure it was done right. If the switch is in a multi-gang box and you are reusing your existing faceplate, then you might want to file down the bottom of the opening on the faceplate to allow access to the restart and reset button. It is a tight squeeze without trimming the faceplate and the buttons would not move to either position. I filed about 1mm off to make sure it fit properly.
Once I had everything put back together it was time to connect it Kasa app, Home Assistant, Google Home and Amazon Alexa. It was simple to set-up Google Home and then share it with Home Assistant, but not so much with Amazon Alexa. I spent hours trying different configurations to share it with Amazon Alexa but it failed every time. The only way to set them up on all devices is to install on Amazon Alexa separately. All other devices can be installed and shared with Google Home. Once everything was setup all voice commands and automations are working perfectly. Given time Amazon will improve their matter support for device sharing.
