Description

This is a box with a beeper and a switch. While using a Konnected Alarm Panel with Home Assistant I was looking for a door beeper leveraging the existing system. Additionally I was looking for an easy way to switch it on and off as needed.

As I was already using Konnected it seemed logical build something around that.

Follow instructions on this page to flash the firmware

2

Install ESP8266 into breadboard

The mini breadboard doesn't have the room to fit the ESP8266 and the beeper so offset the board and have the unused pins not connected to anything.

Connect the Piezo Buzzer

The + pin on the buzzer connects to D7 and the G pin next to D5. This corresponds to "zone 5" in the konnected firmware.
