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.

• Automatic logging of entry events with timestamp and captured photo.

• Motion detection with failed-attempt recognition.

• Instant alerts to the mobile app and via SMS for:

  • Unauthorized access
  • Fire, gas, or water leak detection

• Backup power for continued operation during power outages.

• Kitchen devices control — Video |
• Curtain control — Video |
• Lights control — Video |
