Matter Smart Switch Module DIY Light Relay Switch, Works with Apple Home, Siri, Alexa, Google, SmartThings, Matter Switch Relay Smart Home Automation with Remote Control (2 Gang, 1 Pack)

Great item tiny. Used for my double light switch to make them smart switches then covered with a always on tablet to be a smart home monitor

Very very disappointing. One module had the wiring reversed internally to in software. Another module shorted out. All modules do not report the “HomeKit” ID in iOS so repairing is very difficult (you have to get the unit out of the electrical box unless you have a picture of the ID and/or QR code). I do not recommend these at all. There is also a terrible delay with the switching when using the hardwired switch.

Easy to set up and was easily connected to my HomeKit network. The unit is compact and fit easily in my ceiling fan. This version supports two circuits that are accessible through HomeKit.

I’m using in my garden is working ok

Make sure your Iphone is on the same 2.4 Ghz wifi as the device (for setup) AND your router has IPV6 enabled. I am still debating on that last point but it can't hurt to have IPV6 enabled anyway.

I spended several hours trying to pair it onto my wifi network without those annoying HUB, but still not successful!

I won't be using this since it isn't UL or ETL listed

I had the hardest time getting this to pair with Home Assistant and Homey Pro. Not sure if this is a Matter issue, a device issue, or a hub issue as the process seems way too complicated compared to Zwave and Zigbee. Neither of my setups allowed me to pair directly I had to use the android option and then I was finally able to get it to pair with Home Assistant. I never could get it to pair with Homey Pro.I knocked off a star as this device does not have any UL or ETL markings on it so I honestly would be concered putting this in the wall.
