Latest production-ready version: 09/2020 – 06/2022 Deployment: Smart Home automation system in "16-njy Tapgyr" and "Gorjaw" residential areas.
A complete Smart Home automation platform built on ESP8266 microcontrollers and an ARM-based Linux server. The system supports local and remote control, integrates with multiple IoT devices, and features security, monitoring, and automated comfort adjustments.
Core features:
- MQTT-like device communication between IoT modules and a Raspberry Pi server.
- Automatic local network mode when connected to home Wi-Fi; internet-based remote control when away.
- Flexible device integration — from lights and curtains to heaters, ovens, and security systems.
- Multi-layer security with fingerprint, RFID, and motion detection.
- ESP8266 ESP-01 Microcontrollers
- Microcomputer (ARM Linux, e.g., Raspberry Pi)
- Wi-Fi router
- Relays
- 3.3V → 5V converter
- Power adapter & voltage stabilizer for ESP modules
- SIM900 GSM module (for SMS alerts)
- Various sensors: PIR, water leak, gas, temperature, current, and flow measurement.
- And yes — a bit of patience.
- Lights & light bulbs
- Heater & cooler
- Stove (SIEMENS stove reverse-engineered)
- Curtains
- TV remote control
- Smart sockets & window control
- Water pump control (with water sensor)
- Current & water flow measurement
- CCTV security
- Fingerprint access control (built-in & wireless)
- RFID/NFC card access control
- SIM900 SMS control option
- PIR security sensors
- Face recognition service
-
Entrance doors equipped with RFID and fingerprint sensors.
