Take control of your energy usage with this DIY 3-phase energy monitor! Using three PZEM004T v3.0 modules, this device measures voltage, current, power, and energy consumption for each phase independently. With seamless integration into **Home Assistant** via ESPHome or MQTT, enjoy real-time data visualization, custom automations, and alerts. Affordable, reliable, and open-source, it's the perfect solution for homes or small businesses.  

## Features  

- Monitor energy consumption for **3-phase**, **2-phase**, or **1-phase** setups.  

- Powered by **ESP-01** with onboard LEDs for power and data transfers.  

- Compatible with **Home Assistant** for seamless integration.  

- Access to schematics and PCB Gerber files.  

- Fully customizable for advanced features.  

- **Standalone software version** coming soon.  

## Requirements  

- **Home Assistant** (Standalone software version coming soon).  

- **USB-to-Serial Hardware** to program the ESP-01.
