Available services

After installation this integration adds new services to Home Assistant which can be used in automations. The new services are:

• Overkiz (by Somfy): Set cover position with low speed (tahoma.set_cover_position_low_speed, only added if supported by the device)
• Overkiz (by Somfy): My position (cover) (tahoma.set_cover_my_position)
• Overkiz (by Somfy): Execute command (tahoma.execute_command)
• Overkiz (by Somfy): Get execution history (tahoma.get_execution_history)

Events

This component listen for events returned by Overkiz. In case of command failure, the event will forwarded to Home Assistant.

You can subscribe to the overkiz.event event type in Developer Tools/Events in order to examine the event data JSON for the correct parameters to use in your automations. For example, overkiz.event returns event data JSON similar to the following when your cover is blocked.

{
    "event_type": "overkiz.event",
    "data": {
        "event_name": "ExecutionStateChangedEvent",
        "failure_type_code": 106,
        "failure_type": "CMDCANCELLED"
    },
    "origin": "LOCAL",
    "time_fired": "2021-09-28T20:03:57.102478+00:00",
    "context": {
        "id": "92a84240d914b43ceaf1aee3249568f6",
        "parent_id": null,
        "user_id": null
    }
}

You can find the list of available failure_type here.

Enable debug logging

The logger integration lets you define the level of logging activities in Home Assistant. Turning on debug mode will show more information about unsupported devices in your logbook.

logger:
  default: critical
  logs:
    custom_components.tahoma: debug

Device not supported

If your device is not visible in the device list of Home Assistant (/config/devices/dashboard), you need to turn on debug logging first. Copy your Home Assistant log (Configuration > Logs) and create a new issue.

Device not working correctly

If your device is listed in the device list, you need to turn on debug logging first. Copy your Home Assistant log (Configuration > Logs) and create a new issue.

In order to gather more information, you can use the tahoma.get_execution_history service which will print your execution history to the Home Assistant log. Run the commands via the official vendor app (e.g. TaHoma) and include your log in the issue.

Retrieve HomeKit code

If your hub (e.g. Somfy TaHoma) supports HomeKit natively, your setup code will be added as a sensor in Home Assistant. Look up your hub in Home Assistant and retrieve the value from the 'HomeKit Setup Code' sensor. You can now configure the HomeKit Controller integration in Home Assistant.
