2 Setting in Home Assistant

  1. First make sure your firmware version is at least 1.75.80. latest Firmware (imeter.club)

  2. Configuration IamMeter in Home Assistant Register mapping,

    Single phase WEM3080: modbusTCP in Home Assistant

    Three phase WEM3080T: modbusTCP in Home Assistant

    To use this sensor in your installation, add the following to your configuration.yaml file(for example WEM3080):

    • Remember to add 'scan_interval: 1' after '- name: Modbus_Power' to make homeassistant get power quickly
