2. Integrate with HomeAssistant

2.1 Install HA software

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

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

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 manangement 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

Here you can add the card manually

Or you can copy and paste the following code

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
      - entity: sensor.meter_exportgrid
        name: exportgrid
    type: glance
  - entities:
      - entity: sensor.meter_power
      - entity: sensor.meter_voltage
      - entity: sensor.meter_importenergy
    hours_to_show: 24
