By “everybody” you mean everybody except Amazon. And I had fun hacking those. They were often on sale for like 2 bucks and they came with a battery that was good for like a thousand presses. You had to start the online setup process but not select any products, listen for the button’s msg to Amazon which contained a unique ID. You could then have your own server listen for a “pressed” signal from that button and do whatever you want. I keep meaning to find out if there’s still a way to initialize brand new ones.
I had a couple stuck on walls where I always wished I had put light switches. They toggled lights on and off using ESP-01 microcontrollers. Another one was in my daughter’s bedroom where I had rehung the door to swing the opposite way so she could leave the door partway open without the hall light shining in her face in bed. As the batteries died I replaced them all with buttons run by newer ESP32s… if any of that makes sense.
