A low cost (sub $20) smart doorbell based around the "TTGO T-Camera ESP32".

Features:
* Live video feed
* OLED screen
* PIR motion sensor

*Firmware is based on ESPHome, so a home-assistant install is required.*

Required parts:
* TTGO T-Camera ESP32 (fish-eye version)
* cherry mx style switch
* us #8 or similar countersunk screw (2x)
* m3x6 bolt and threaded insert (at least 2)
* short bit of cable to connect switch to esp32
* some sort of way to power it

Most likely isn't waterproof so probably install somewhere it won't get wet.
