This is a box designed for a button. You can connect it to Home Assistant and start automations with it. It uses an LED ring to give the user feedback or to block the button by showing a red color.

On the bottom side, there is a slot where you can slide in a wooden stick. The lid is glued on the top with hot glue. The hole for the power cable is also glued so no moisture can enter the box.

The button has a diameter of 12 mm, and the LED ring is a WS2812b smart LED ring. I used a normal ESP32 and flashed it with ESPHome.

Materials: 

LED Ring: WS2812b LED Ring, 50 mm, 16 LEDs
