New Home Assistant Integration – for Multiple Devices ⚡

What has changed in the new integration?

• New domain: the integration now runs under the name greenhess.

• Support for multiple ADA devices:

  • ADA P1 Meter

  • ADA One

  • ADA Bridge

  • ADA PZIOT-E02

• Multiple meters on the same network: multiple ADA devices can be added simultaneously and are easily identifiable using different prefixes.

• Energy panel support: energy sensors also appear on Home Assistant's own Energy interface.

• Real-time data: 10-second updates → fast, accurate, and stable data connection.

How does it work?

The integration uses the REST API of ADA devices available on the network (the /json endpoint), and Home Assistant automatically detects the sensors.
Each device comes with a predefined set of sensors:

• Total energy consumption and feed-in

• Breakdown by tariff

• Instantaneous power (import/export, also per phase)

• Reactive energy and power

• Voltage, current, power factor

• Serial number, tariff, timestamp

This data can be used directly for charts, automations, notifications, or Home Assistant's Energy panel.

Step-by-step setup

1. Install the integration from the GitHub page (HACS recommended).

2. Search for the GreenHESS integration in the Home Assistant integrations.

3. Provide the device type (e.g., ADA P1 Meter), host or IP address, and port.

4. If you have multiple devices, use a prefix for easier identification.

5. After successful connection, the sensors will automatically appear in Home Assistant.

Why should you upgrade?

• More ADA devices → more data in one place

• Simpler configuration

• Better integration with the Home Assistant ecosystem

• Prepared for future ADA devices
