Integrate IAMMETER`s energy meter into Home assistant(by core integration)

Integrate IAMMETER Wi-Fi Energy Meter into Home Assistant by HA core integration

1. Introduction

Integrating IAMMETER Wi-Fi energy meters into Home Assistant provides effective real-time energy monitoring solutions. IAMMETER supports multiple integration methods with Home Assistant:

• Direct Integration: Simplest setup (covered in this tutorial).
• Modbus/TCP Sensor: Provides higher performance, enabling data updates every second. Learn more.
• MQTT Sensor: Flexible integration using MQTT protocol. Learn more.

Home Assistant is a popular open-source home automation platform (official site). IAMMETER energy meters seamlessly integrate with Home Assistant, offering precise energy data for smart home and solar PV applications.

2. Step-by-Step Integration of IAMMETER into Home Assistant

Demo Example

You can remotely control lights and observe real-time power changes.

2.1 Installation of Home Assistant

Install the latest Home Assistant version (0.107.0.dev20200310 or later).

2.2 Configuration

Add IAMMETER sensor configuration to configuration.yaml:

yaml复制编辑sensor:
  - platform: iammeter
    host: 192.168.1.6
    name: meter

Tip: Double-click the meter icon from your local network to find its IP.

2.3 Verify Sensor Integration

Restart Home Assistant and check that the sensors appear in the entity list:

2.4 Available IAMMETER Sensors

Single-Phase Meter (WEM3080)

Three-Phase Meter (WEM3080T)

Includes voltage, current, power, energy, frequency, and power factor for each phase A/B/C.

2.5 Customize Home Assistant Dashboard (Lovelace)

Edit your Lovelace dashboard:

Or copy this card configuration:

yaml复制编辑cards:
  - cards:
      - entity: sensor.meter_voltage
        max: 300
        min: 100
        name: voltage
        type: gauge
      - entity: sensor.meter_power
        max: 5000
        min: 0
        name: power
        type: gauge
    type: horizontal-stack
  - entities:
      - entity: sensor.meter_voltage
      - entity: sensor.meter_power
      - entity: sensor.meter_importenergy
      - entity: sensor.meter_exportgrid
    type: glance
  - entities:
      - entity: sensor.meter_power
      - entity: sensor.meter_voltage
      - entity: sensor.meter_importenergy
    hours_to_show: 24
    refresh_interval: 0
