This file contains the main logic for the PVRouter, including the setup and loop functions, as well as interrupt service routines (ISRs) and utility functions for managing load priorities, temperature sensing, and telemetry data.

• Interrupt-Driven Analog Conversion: Uses an ISR to process ADC data for voltage and current sensors.
• Load Management: Includes functions for load priority rotation, forced full power, and dual tariff handling.
• Telemetry: Sends telemetry data in various formats (e.g., IoT, EmonCMS).
• Temperature Sensing: Supports DS18B20 sensors for temperature monitoring.
• Watchdog: Toggles a pin to indicate system activity.

Function Documentation

processTemperatureData()

void processTemperatureData

(

)

Processes temperature data from DS18B20 sensors.

This function reads temperature values from all connected DS18B20 sensors, filters out invalid readings, and updates the telemetry data structure with valid temperature values. Invalid readings are identified as 85.00°C (encoded as 8500) with a delta greater than 5.00°C (encoded as 500) from the previous reading. After processing, it requests new temperature measurements for the next cycle.

Note

This function assumes that temperature values are stored as integers multiplied by 100 for precision.

Precondition

The temperatureSensing object must be initialized and configured with the connected DS18B20 sensors.

Postcondition

The tx_data.temperature_x100 array is updated with the latest valid temperature readings.
