Doorbell I use with Home-Assistant. Houses:
ESP32-c6-supermini board (e.g. from aliexpress)
TP4056 based battery protection/charging board
18650 battery with battery holder
Cherry MX-style switch as a button
5kOhm resistor for connecting the switch to a GPIO pin of the ESP32 board
See the photos for how I put the parts together. The backside can be screwed to a wall, and the main case can be slid in and fastened with a M3 screw at the bottom if you want. Id recommend to slide the parts in and out a few times to make it go a bit smoother. Depending how you program the ESP32, the battery for a simple doorbell application can last up to about 3 months. Depends what you do with it :)
Please let me know how you use it, if you use it!
