House alarm system based on ESP32
Copyright (c) 2017-2020 by Danny Backx
This alarm system is designed to work with a bunch of similar controllers.
The basis is an ESP32, which can be equipped with a small touch display, and a 433MHz radio receiver. In all, less than €20 (or $) per controller. A design for a small PCB to connect them all is available.
The nodes communicate with each other. Auto-discovery via multicast, communication via JSON.
You can choose which hardware and capabilities go in each individual controller, and configure them accordingly.
The software needs a bit of configuration to talk to the hardware, this is set up as small json files.
Remote cheap sensors (motion, smoke) are readily available - they usually send their ID via 433MHz radio when in alarm.
Remote control via (Android) smartphone is work in progress.
Build environment is ESP-IDF, as recommended by Espressif.
