DIY Smart Doorbell

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.
