Setup The SMLight SLZB MR3 With Home Assistant - Part 3

Setup The SMLight SLZB-MR3 With Home Assistant - Part 3

In this third part of this video series I will be showing you how to setup the SLZB-MR3 in Home Assistant and get it setup for Matter over Thread as the Open Thread Border Router in Home Assistant and then I will show you how to adopt a Thread Smart Plug, in this example I will be using a Meross MSS315 Smart Plug as I found it one of the easiest to use & setup with Thread.

I have had suggestions for a Part 4 video, so I may well add another video to this series, so keep a look out for some more videos in due course on my YouTube channel MrTimTech.

Please note that this tutorial series should also work just the same for the SLZB-MR1 and SLZB-MR2, so you should be able to still follow along even though I am using an SLZB-MR3 in this video series!
