Introduction

The Wi-Fi Energy meter of IAMMETER( WEM3080 and WEM3080T) had been an integration of Home Assistant.

IAMMETER Wi-Fi Energy meter in Home Assistant

Besides reading data from the local api of hardware (refer to above link) ,you can also subscribe the topic from IAMMETER directly. This document will show how to integrate with Home assistant by subscribing topic from IAMMETER cloud .

Configuration in Home Assistant

MQTT setting

Use IAMMETER MQTT server only

Add the following to your configuration.yaml file:

Replace the Username/your MQTT password to the MQTT username/password in IAMMETER.

mqtt:

  broker: mqtt.iammeter.com

  client_id: homeassistant

  keepalive: 60

  username: Username

  password: yourmqttpassword

There is already MQTT server in Home assistant

You need do the MQTT bridge firstly.

Data parser

WEM3080(single phase Wi-Fi energy meter), replace the SN with the real SN of your product.
