ISR-based projects demonstrate how to use ESP8266TimerInterrupt, ESP32TimerInterrupt and TimerInterrupt Library
Turn a cheap, dumb smoke alarm into a somewhat smart version. Connect an ESP8266 to it so you can use smoke alarms in Home Assistant automations.
Universal sound alerts for deaf residents: one microphone detects smoke (T-3), CO (T-4), doorbell and knocks by beep pattern, then strobes a light and buzzes your watch. Rule-based, auditable, ~EUR 40.
Get alerts for smoke detector / smoke alarm by listening with a microphone and taking a FFT. For my dog.
Home Assistant component for FireAngel Pro Connected using custom Arduino-based controller
