For most people, the thought of replacing an outlet or switch is daunting to say the least. My IKEA smart bulbs are going on 7 years old and still working great.
I did replace every single outlet and switch in my house when I moved in, but that was before I knew about ZigBee or Zwave, and well before matter existed.
I don’t feel the need to replace most of my switches and half of my outlets again.
We’re a little behind schedule.
