I had a few Google Home devices, they had a switch to turn off the mic. I assume it was legit switch, because the thing literally yelled at you and had bright red lights any time you muted it. It literally said “The mic is turned off” every time it booted up in a voice that reminds me of a child tattling on their sibling.
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.
