PowerCollection Life - Tasmota Energy Monitor

Version: 0.1.0-dev (Developer Preview)

Introduction

PowerCollection Life is a real-time energy monitoring application that connects to Tasmota-enabled smart plugs and visualizes electrical consumption metrics. It provides a web-based dashboard to monitor voltage, power consumption, apparent power, and current in real-time with interactive charting and CSV data export capabilities.

Key Features

• Real-time Monitoring: Continuously poll Tasmota smart plug devices for live energy metrics
• Interactive Charts: Visualize voltage, power, apparent power, and current consumption with dynamic rendering
• Selective Display: Toggle visibility of different metrics on the chart
• Data Export: Download monitoring data as CSV for further analysis in spreadsheet applications
• Configurable Polling: Adjust the data collection interval (default: 5 seconds)
• CORS Proxy: Built-in Express proxy server to bypass browser cross-origin restrictions

Installation Instructions

Prerequisites

• Node.js (v14 or higher)
• A Tasmota-enabled smart plug device on your local network
• A modern web browser (Chrome, Firefox, Safari, Edge)

Setup Steps

1. Clone or download the project

   git clone <repository-url>
   cd PowerCollectionLife

2. Install dependencies

   npm install

3. Configure the Tasmota device IP address

   • Open proxy.js
   • Update the IP address in the fetch URL from 192.168.2.128 to match your Tasmota device's IP address

   const r = await fetch('http://YOUR_TASMOTA_IP/cm?cmnd=Status%2010');

4. Start the proxy server

   node proxy.js

   The server will run on http://localhost:3000

5. Open the application

   • Open PowerCollection.html in your web browser
   • The interface will automatically connect to the proxy server at http://localhost:3000/tasmota

6. Start monitoring

   • Click the Start button to begin data collection
   • Adjust the polling interval (in seconds) as needed
   • Toggle visibility of metrics using the checkboxes
   • Click Download CSV to export data for analysis
