[Custom Integration] Ambientika Ventilation — HACS integration for Südwind Ambientika units

Hi everyone,

I have developed Ambientika Ventilation, an independent Home Assistant
integration for cloud-connected Südwind Ambientika ventilation units.

Repository:

What it provides

  • UI-based configuration and reauthentication
  • Automatic discovery of houses, zones, rooms, and devices
  • Fan control with power, speed, Turbo, and Night preset
  • Operating mode, humidity target, and light sensor controls
  • Weekly schedule status and schedule enable/disable control
  • Temperature, humidity, air quality, filter, and alarm sensors
  • Filter reset button
  • Firmware, device-role, topology, signal-strength, and cloud diagnostics
  • Master/slave and Gemini-specific handling
  • English and German translations

The integration uses stable entity IDs based on device serial numbers, supports
dynamic device discovery, and performs an immediate state read-back after
commands.

Reliability and privacy

A shared coordinator ensures that each device is queried only once per update.
Temporary API failures, rate limits, and offline devices are handled
individually without blocking the remaining installation.

Downloadable diagnostics exclude passwords, tokens, email addresses,
user-created names, complete serial numbers, and raw API responses.

Compatibility

The integration has currently been tested with two existing Ambientika Ghost
installations, producing 59 entities in total.

Feedback from users with other models and configurations would be especially
helpful, including:

  • Ambientika Smart
  • Ambientika Advanced+
  • Ambientika Wireless+
  • Ambientika Solo+
  • Different master/slave configurations
  • Active weekly schedules

Installation

The integration is currently awaiting inclusion in the default HACS catalog:

Until then, it can be installed as a custom HACS repository:

  1. Open HACS → Integrations
  2. Select the three-dot menu and Custom repositories
  3. Add:
    https://github.com/SoftwareSchmied/ha-ambientika-ventilation
  4. Select Integration as the category
  5. Install Ambientika Ventilation
  6. Restart Home Assistant
  7. Open Settings → Devices & services → Add integration
  8. Search for Ambientika Ventilation

Important notes

  • This is a cloud integration and requires access to the Ambientika cloud.
  • Version 0.9.0 should still be considered a public preview.
  • The integration is independently developed and is not affiliated with or
    endorsed by Südwind or Ambientika.
  • It uses the separate ambientika_ventilation domain and can technically
    coexist with the older ambientika integration. Running both against the
    same devices is not recommended because it produces unnecessary API traffic.

Feedback

Bug reports, diagnostics, and compatibility reports are very welcome:

Please mention the device model, topology, and Home Assistant version. Do not
post passwords, access tokens, full serial numbers, or raw account data.
