🚯 ♈️ 🏜️ We make an access control and management system (ACS) for a smart home 🏳️‍🌈 🏵️ 💋

Introduction

About a year ago, I started preparing for the move and putting together a prototype of a smart home. As a control system, I chose the most popular and actively developing solution - Home Assistant. As the smart home grew overgrown with sensors, the question arose about the security system, which, if something happened, would raise the alarm and inform me (neighbors) about uninvited guests. I don't see the need for a system from private security companies yet, so I decided to do everything myself.

How it works: an opening sensor is placed on the front door, which, using the Zigbee protocol, informs the smart home server that someone has entered the apartment. An alarm is triggered in "quiet mode" ( "triggered" event in embedded integration ; this does not appear in any way, but the countdown goes until the siren starts). If the lock is not removed within the time specified in the settings (by entering a code or NFC tag), the siren and light indication will start.

What is collected from:

ESP32 WROOM DevKit v1 (in theory, you can replace any ESP by changing the config for it)
RFID / NFC module PN532
Connecting wires (6 pieces)
3D printed case
Xiaomi Gateway 2 (which is locally controlled) I plan to use as a speaker and indicator light
Door opening sensor from Aqara
