IPEM SIX | ESP32C5 | DUAL ATM90E32 IoT Mains Power Energy Monitor

IPEM SIX - ESPHome Example Code

This is a working ESPHome YAML development code for IPEM SIX, for Home Assistant.

Summary

IPEM SIX C5 provides a complete energy monitoring platform:

✅ 6 CT channels
✅ Dual ATM90E32 metering
✅ Import/export detection
✅ Per-channel energy tracking
✅ Home Assistant native integration
✅ WiFi diagnostics
✅ Health monitoring
✅ Configurable load alerts
✅ OTA updates
✅ ESP32-C5 performance platform

Designed as a professional-grade residential and small commercial energy monitoring solution.

Timeline

Now the code has been released and tested, other variants will also be provided.

• Split Phase
• Two Phase, over the Two Banks
• Three Phase

Code Overview

IPEM SIX C5 is a professional 6-channel dual-bank energy monitoring device based on the ESP32-C5 platform and dual ATM90E32 energy measurement ICs.

Demonstrate the power of the IPEM SIX by reading the all the data from the six current clamps and input voltages, and provide a large range of information.

Provide:

• Live sensor updates
• Configuration control
• Device status
• Diagnostics

The device code presents:

• 6 independent CT current channels
• Dual-bank monitoring architecture
• Real-time power monitoring
• Import/export power calculation
• Energy accumulation (kWh)
• Voltage and frequency measurement
• Power factor and reactive power monitoring
• Internal temperature monitoring
• Wi-Fi diagnostics
• Health/Status monitoring
• Configurable load activity thresholds
• LED heartbeat indication

Designed for integration with Home Assistant via ESPHome API.

Basic Examples

During development, I took baby steps in understanding how YAML worked and how to integrate the various elements of the IPEM SIX board. These examples have been included for your information, in the Basic Examples folder.

Status

The code should work as it is but you will ideally need to update the ESPHome API details, which I have xxxx out.

Enable Home Assistant API

api:
  encryption:
    key: "xxxx="

ota:
  - platform: esphome
    password: "xxxx"

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Wren-C5-Test Fallback Hotspot"
    password: "xxxx"
