AdPower PSU-level Power Logger

A simple Python-based tool to log power consumption data from AdPower Wattman measurement devices via serial communication. This utility enables PSU-level power monitoring and logging for energy profiling and diagnostics.

Features

• Collects real-time power usage (in Watts) and power factor (PF) via serial input
• Supports logging at configurable time intervals and durations
• Compatible with AdPower devices using /dev/ttyUSB0 serial interface

Requirements

• Python 3.6+
• AdPower power measurement device connected via USB serial
• pyserial

Install dependencies:

pip install -r requirements.txt

Usage

The monitoring start time is adjusted so that the first measurement aligns with the next full-minute boundary based on the interval.

python powerlog.py [-i INTERVAL] [-t TIMEOUT]

• -i: Logging interval in seconds (default: 5 seconds)
• -t: Total monitoring duration in seconds (default: 120 seconds)

Output

Each log entry contains 4 columns:

• Date and time (MM-DD HH:mm:ss)
• Average power (Watt)
• Accumulated energy during the interval (joules)

Example output:

07-17 15:24:54 153.6000 304.8745
07-17 15:24:56 153.2000 306.4358
07-17 15:24:58 153.3861 306.8286

Notes

• By default, this script assumes the device is connected to /dev/ttyUSB0. Modify adpower.py if your serial port differs.
• Ensure your user has permission to access the serial device (e.g., add to dialout group on Linux).
