Home Assistant Integration

The ADA P1 Meter can be integrated with the Home Assistant system, allowing energy consumption and feed-in data to be displayed directly within your home automation system.

Installation in Home Assistant​

The integration is available via the Home Assistant Community Store (HACS):

  1. Open the Home Assistant interface and select the HACS menu.
  2. Search for the "ADA P1 Meter" integration.
  3. If you can’t find it, manually add this repository to HACS:
https://github.com/greenhess/adap1meter
  1. In the top right corner of HACS, select Custom repositories.
  2. Enter the URL above, select the Integration type, then click Add.
  3. Install it, and then restart Home Assistant.

For more detailed information, visit the GitHub page:

Displaying Entities on the Homepage​

Since the ADA P1 Meter creates multiple sensors, they are not automatically shown on the main dashboard. You’ll need to manually add them:

  1. Click the Edit button in the top right corner of the homepage
  2. Select the element (e.g., card, chart) where you want to show the data
  3. Click Select entities
  4. Choose the desired sensor (e.g. sensor.ada12_voltage_phase_l1, sensor.ada12_instantaneous_power_import, etc.)

You’ll need to do this for each card individually, but it gives you full control over what is shown.

Setting Up the Energy Panel​

Home Assistant’s Energy panel only displays entities that have the proper metadata. For ADA P1 Meter sensors, it’s recommended to create template sensors.

Example entry in configuration.yaml:​

template:
  - sensor:
      - name: "Total Imported Energy (ADA P1 Meter)"
        unique_id: total_imported_energy_ha
        state: "{{ states('sensor.ada12_active_import_energy_total') | float }}"
        unit_of_measurement: "kWh"
        device_class: energy
        state_class: total_increasing

      - name: "Total Exported Energy (ADA P1 Meter)"
        unique_id: total_exported_energy_ha
        state: "{{ states('sensor.ada12_active_export_energy_total') | float }}"
        unit_of_measurement: "kWh"
        device_class: energy
        state_class: total_increasing

⚠️ Note: The entity names like sensor.ada12_active_import_energy_total may differ in your setup. Check the actual names under Developer Tools > States in Home Assistant.

What Can It Be Used For?​

  • Measuring energy consumption and feed-in
  • Displaying data on the Energy panel with graphs
  • Automations (e.g., responding to overload conditions)
  • Combining with other measurements (e.g., PV systems)

This integration allows the ADA P1 Meter to become a full-fledged part of your home automation ecosystem.
