Battery-operated Devices

Battery-operated devices are usually in sleep mode until they are awakened, e.g. by a button press or detected motion. They do not contribute to message forwarding in a mesh network but are pure transmitters. This design approach is crucial for several reasons:

  • Energy Efficiency: By spending most of their time in sleep mode, these devices can operate for months or even years on a single battery

  • Specific Functions: They excel at specific tasks like:

    • Motion detection
    • Switch operations
    • Environmental sensing
    • Door/window status monitoring

  • Network Interaction:

    • Wake up only when needed (user interaction or sensor trigger)
    • Send their messages to nearby mains-powered devices
    • Return to sleep mode immediately after transmission
    • Receive messages only during brief wake periods
    • Rely on mains-powered devices to store messages for them

  • Installation Flexibility: Can be placed anywhere without requiring power cables, making them ideal for:

    • Remote locations
    • Mobile applications
    • Hard-to-wire areas
    • Temporary installations

While these devices don't participate in message routing, their energy-efficient design makes them essential components for flexible and comprehensive mesh network solutions.
