Overview

The ThingsBoard module provides integration with the ThingsBoard IoT platform. It allows for telemetry data to be published and commands to be processed via MQTT.

Features

• MQTT-based communication with ThingsBoard.
• Configurable settings for server, port, access token, and publish topic.
• Telemetry data publishing.
• Command processing (future implementation).

UI Hardware / Pinout Configuration

No specific hardware configuration is required for this module. It relies on network connectivity for communication with the ThingsBoard server.

Telemetry Provided

• Custom telemetry data as defined by the application.
• Example telemetry attributes include:
  • time: Current timestamp.
  • voltage: Voltage readings.
  • freeram: Available free RAM.
  • rssi: Wi-Fi signal strength.
  • wifiUptime: Duration of Wi-Fi connectivity.

Telemetry Consumed

• None at the moment.

Commands Provided

• None presently implemented.

Commands Consumed

• None presently implemented.

Additional Information

• Web Interface: A web-based configuration page is available at /tb. This allows users to configure MQTT settings such as server, port, access token, and publish topic.
• Settings Management: The module saves settings to a file (tb.settings) and loads them on startup. Invalid settings are automatically reset to defaults.
• Telemetry Posting: Telemetry data is sent to the ThingsBoard server only when changes are detected, reducing unnecessary network traffic.
• Dependencies: This module depends on the MQTTClient class for MQTT communication and requires network connectivity to function.
• Future Enhancements: Command processing is planned for future implementation, enabling bidirectional communication with the ThingsBoard platform.
