Building IoT AQ Sensors / Doorbell Chimes for Ubiquiti UI Protect in Home Assistant with ESPHome

In the previous video I mentioned that I built a variety of ESP32 media speakers in Home Assistant via ESPHome to use as doorbell chimes for Unifi Protect. This video walks through the different devices, including how I ended up putting Air Quality (AQ) sensors in most of the designs. Links to STL/Code below.
