The ekey bionyx {% term integration %} allows Home Assistant to receive events from your ekey fingerprint reader.

Prerequisites

• The ekey bionyx app.
• The ekey device needs to be set up in plus mode in the app.
• The ekey bionyx Third-Party API needs to be enabled in the app.

{% include integrations/config_flow.md %}

{% tip %} Prefer using local IPs when setting up the {% term integration %} instead of domain names because the events will be more responsive. {% endtip %}

Once the {% term integration %} is added, open the ekey app and assign events to the fingers you wish to use as triggers.

Supported functionality

The ekey bionyx {% term integration %} provides the following entities.

Events

The functions defined during setup are represented in Home Assistant as events. You can use these events as triggers in automations.

Limitations

• The ekey {% term integration %} allows only five functions per ekey system.
• You cannot link multiple Home Assistant instances to the same ekey system.

Removing the integration

Based on the limited lifetime of the token, you have two options for cleanly resetting the connection to Home Assistant:

• Delete the {% term integration %} in Home Assistant, set it up again (triggering the deletion process), and abort when you are in the step of naming the functions.
• Delete the {% term integration %} in Home Assistant, then disable and re-enable the Third-Party API in the ekey app (this resets all functions and webhooks, even outside of Home Assistant).
