Introduction to IoT and Domotics
May 21, 2024
1 What is Domotics?
Domotics, derived from domus (house in Latin) and automatics, refers to home
automation. It involves integrating technology to manage home functions auto-
matically, enhancing comfort, security, energy efficiency, and health. This field
includes various electrical devices like appliances, security systems, and energy
management tools.
2 Key Benefits of Domotics
• Comfort: Automates daily tasks (e.g., coffee maker starts at 8 AM).
• Security: Includes alarms and surveillance cameras.
• Energy Savings: Manages energy use efficiently (e.g., adjusts heating
during off-peak hours).
• Health: Supports telehealth and remote medical monitoring.
3 Technologies in Domotics
Domotic systems can be implemented using different technologies:
• Wireless Technology: Uses radio frequencies (RF) for communication,
suitable for light renovations.
• Power Line Communication (PLC): Transfers data over existing elec-
trical wiring, avoiding extensive modifications.
• Wired Bus Systems: Common in new buildings or major renovations,
using dedicated cables to connect devices.

4 Structure of a Domotic System
• Central Hub (Box Domotique): The brain that processes information
and triggers actions.
• Sensors: Collect data (e.g., temperature, humidity, presence).
• Actuators: Operate devices (e.g., lights, heaters, appliances).
5 Communication Protocols
• Wireless Protocols: Include Zigbee, Z-Wave, Bluetooth, etc., for short-
range communication.
• Long-Range Protocols: Like LoRa and Sigfox, offer broader coverage
with low power consumption.
• PLC: Uses electrical wiring for data transmission, turning the home into
a smart network.
• Wired Bus Systems (e.g., KNX): Ensure robust communication be-
tween devices, ideal for complex setups.
6 Domains of Domotics
• Security: Alarm systems, cameras, and surveillance.
• Comfort: Automation of daily tasks and device control.
• Energy Efficiency: Optimizes energy use.
• Health: Facilitates remote healthcare services.
• Communication: Connects devices via Wi-Fi, Bluetooth, etc.
7 Example of Domotic Software
Home Assistant:
• Function: Acts as a central server to control various devices.
• Features: Can be installed on low-power computers (like Raspberry Pi),
uses multiple integrations (MQTT, Google Assistant, HomeKit).
• Control: Accessible via web interface or mobile app for remote operation
and automation based on conditions.
This simplified guide highlights how domotics integrates various technologies
to automate and improve home living, providing comfort, security, and efficiency
through intelligent device communication and management.
