Energy monitor in HomeAssistant

This article is about how to integrate the energy meter of IAMMETER into Home Assistant. But the energy meter of IAMMETER does not only support third-party platforms such as Home Assistant but also has a powerful IAMMETER-cloud and app service, more information please refer to

Application introduction about the IAMMETER system and smart energy meter

Use the 3 phase energy meter the way you like

1. Introduction

No. Products Description
1 3 phase energy monitor WEM3080T : three phase wifi energy meter
2 wifi power meter WEM3080 : single phase wifi energy meter

HomeAssistant (https://www.home-assistant.io/) is an open source home automation system.

IAMMETER WiFi energy meter can be integrated with HomeAssistant system.

2. Integrate the energy meter of IAMMETER into Home Assistant

Demo show

This is a simple demo of integrating the bi-directional Wi-Fi Energy meter to Home-Assistant system,

URL: http://ha.iammeter.com:18123/ username: iammeter password: iammeter

You can remotely switch ON/OFF the three lights and see how the power changes accordingly.

2.1 Install HA software

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

install the home assistant

2.2 Configuration

To use the Iammeter sensors in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
sensor:
  - platform: iammeter
    host: 192.168.1.6
    name: meter

configure energy meter of IAMMETER in Home assistant

Tips: You can find your meter and check its host IP address by double clicking its icon in the network of your PC which is connected to the same home Wi-Fi network Network

2.3 Find your meter in HA

Restart the server management and reconnect to it, then you will see the entity of the meter if the meter is already connected to the Internet.

2.5 Edit your lovelace

edit your lovelace to display the power and energy data

add a lovelace card of Home Assistant

Here you can add the card manually

select the card you want to display the energy data

Or you can copy and paste the following code

edit the card property

cards:
  - cards:
      - entity: sensor.meter_voltage
        max: 300
        min: 100
        name: voltage
        theme: default
        type: gauge
      - entity: sensor.meter_power
        max: 5000
        min: 0
        name: power
        theme: default
        type: gauge
    type: horizontal-stack
  - entities:
      - entity: sensor.meter_voltage
        name: voltage
      - entity: sensor.meter_power
        name: power
      - entity: sensor.meter_importenergy
        name: importenergy
