Linkbox+ Home and Building Connectivity Hub - Introduction, Specifications and Use Cases

1. Introduction
Linkbox+ is the core connectivity hub of our AbraOS ecosystem, designed to serve as the central unit for managing residential connectivity, energy and smart home and building systems.
Our Linkbox+ enables seamless integration of home automation, energy management, and safety solutions. This makes it a powerful and versatile solution for OEM and Whitelabel partners aiming to offer reliable connectivity in residential and building environments.

2. Connectivity and Integration Capabilities
Linkbox+ offers multiple connectivity options that ensure robust operation and communication with the Abra Cloud. Cloud connection and internet access is ensured via 4G, WiFi, or Ethernet, allowing remote monitoring and control through the Abralife app or Abra Portal. Locally, it supports communication with devices through Zigbee, Bluetooth, WiMEA (our proprietary wireless protocol for critical systems), as well as Modbus and BACnet over RS-485 or Ethernet/IP. (See complete technical specifications further down)

Key Features:

• Multi-Protocol Support: Linkbox+ integrates various protocols, including 4G, WiFi, Zigbee, Bluetooth, WiMEA, Modbus, and BACnet, providing flexibility to connect diverse smart devices.

• Local and Remote Control: Connects up to 80 wireless devices and allows remote management of systems via the Abralife app, available on both Android and iOS.

• No Internet Dependency and Battery back-up: Linkbox+ can function without an active internet connection, enabling it to continue detecting leaks, managing alarms, and controlling water valves locally even when the power supply is disrupted (in case of black-outs etc.) thanks to an integrated battery.

3. Benefits for OEM Partners and Developers
Linkbox+ serves as an ideal connectivity hub for partners looking to integrate robust, multi-protocol communication into their smart home or building automation solutions:

• Centralized Building and Energy Management: Provides a unified solution for managing a wide range of devices, safety sensors, HVAC and energy management or access controll management systems, making it a convenient choice for OEMs developing comprehensive residential connectivity products.

• Advanced Safety and Security: Integrates advanced safety features such as water leak detection, smoke alarms, and tamper detection, enhancing the value proposition for smart home users.

• Reliable Performance: With options for 4G, WiFi, and wired Ethernet, Linkbox+ ensures consistent connectivity, while an integrated backup battery offers power during outages, ensuring uninterrupted service.

Key Functionalities
