About
OT Control establishes a Bluetooth Low Energy (BLE) connection to Optimum Tracker’s Solar Tracker Control Unit (TCU) and provides a real-time overview of the tracker’s operational status.
The application allows technicians to:
Discover nearby TCU devices via Bluetooth
Connect securely to a tracker control unit
Monitor device status and operational values
Configure essential system parameters
Perform maintenance and diagnostics
OT Control communicates with Digi XBee 3 devices via Bluetooth. These devices are connected to the tracker controller through a serial interface and expose operational data through a Modbus RTU interface.
This application provides a safe and convenient interface for interacting with the tracker control system used in Optimum Tracker solar installations.
OT Control is intended for use by trained technicians operating Optimum Tracker equipment.
