README

Watto-Meter

Description

Watto-Meter is an open-source project designed to measure the power consumption of a device connected via USB-C. This project combines dedicated hardware and embedded software to provide the following features:

• Power measurement: Voltage, current, and power are measured.
• Data logging: Measurements are saved on an SD card in CSV format.
• Web interface: Data is accessible via a web page hosted on the device. The interface also allows:
  • Starting or stopping measurements.
  • Downloading or deleting recorded CSV files.
• Web API: A REST API enables remote control of the device and access to the data.

Key Features

1. Measurement:

   • Voltage (Volts)
   • Current (mA)
   • Power (Watts)

2. Data logging:

   • Measurements are saved on an SD card in CSV format.

3. User interface:

   • An intuitive web interface to view data, configure the device, and manage recorded files.

4. REST API:

   • Remote control via HTTP endpoints to start/stop measurements, configure the device, or download files.

Software Development and Deployment

Prerequisites

• PlatformIO Core
• A Watto-Meter board (see the hardware/ folder)
• An SD card for data logging

Instructions

1. Clone the project:

   git clone https://github.com/esiealab/watto-meter.git
   cd watto-meter/software
   

2. Configure the project:

   • Open the folder in PlatformIO.
   • Edit the platformio.ini file if necessary and the WiFiConfig.h (WiFi SSID, password.).

3. Build and upload the firmware:

   pio run --target upload
   

4. Upload folder data to the filesystem: According to this guide:

   #Build the filesystem image
   pio run --target buildfs
   #Upload the filesystem image
   pio run --target uploadfs
   

Or you can open the PlatformIO menu and click on the following buttons:
