A companion device for door close alerts from automations

[CrazyCoder]

Just to document my little project. It's ESPHOME esp2866 simple device with a buzzer and 4x4 WS2812 LED matrix I use to alert when any automation is about to close the door.

ESPHOME config: gdalert.yaml.

Bottom shield is completely optional, and I use it only for mounting with a Velcro-like adhesive tape. You can opt for a custom 3D-printed enclosure or your own creative way of attaching it to a surface.

BOM:

• ESP8266 D1 Mini
• x2 proto shields for D1
• Active buzzer module (use 3.3V for VCC and D5 for control, inverted)
• 4x4 WS2812 matrix (controlled via RX pin)

You can use any 5V addressable LED strip/matrix/etc, but this one was easy to mount and looks nice.

Trigger a switch from Home Assistant automation. 5s and 10s switches turn off automatically after the specified time. You can control the light and buzzer independently.
