The video shows an application of the ESP32 custom sensor board I developed to create a Security Alarm System with Home Assistant.
Small size allows you to hide all the sensors and makes the alarm system practically invisible.
The device can be integrated in Home Assistant without any configuration, the system uses MQTT Discovery on ESP32 to autoconfigure itself.
The system is developed for a low battery consumption using an hardware timer.
You can find ESP32 source code and sensor schematic on:
