Everything that I am using in my smart home can be found here on my Amazon page:
I use Home Assistant running on a Raspberry Pi 4. I'm using a solid state drive plugged in with this cable so I don't have any SD card failures. Also, I'm using this Zigbee/Z-Wave combo USB stick plugged into this USB extender.
I'm mainly using HomePods with some Google Smart Displays as well.
Almost everything I cover in the sensor video I made is still what I use.
Here's a list of devices I use in my smart home.
