# Example configuration.yaml entry

sensor:

  - platform: iammeter

    host: 192.168.1.6

name: meter

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.

2.4 Sensors

Sensors available in the library:

Single Phase WiFi Energy Meter (WEM3080)

Three Phase WiFi Energy Meter (WEM3080T)

2.5 Edit your lovelace

Here you can add the card manually

Or you can copy and paste the following code

cards:

  - cards:

      - entity: ter_voltage

        max: 300

        min: 100

        name: voltage

        theme: default

        type: gauge

      - entity: ter_power

        max: 5000

        min: 0

        name: power

        theme: default

        type: gauge

    type: horizontal-stack

  - entities:

      - entity: ter_voltage

        name: voltage

      - entity: ter_power

        name: power

      - entity: ter_importenergy

        name: importenergy

      - entity: ter_exportgrid

        name: exportgrid

    type: glance

  - entities:

      - entity: ter_power

      - entity: ter_voltage

      - entity: ter_importenergy

    hours_to_show: 24
