Create custom device in custom_component but devices immediately deleted

Development

Hello,

I am creating a custom component that builds a set of simulated sensors. Im trying to represent each sensor as a device that consists of two entities, the sensor itself and a battery.

Now im able to use my custom component to create a series of binary sensors… no problem there. They show up in the UI under entities in the configuration tab.

I also added code to build devices using the function device_registry.async_get_or_create().

Here’s the code im using:


        device_registry.async_get_or_create(
            config_entry_id=unique_id,
            identifiers={(unique_id)},
            manufacturer="Company",
            name=str(device_name),
            model="Simulated",
            sw_version="0.1",
        )

This code is in fact creating a device. I can see it in the .storage/core.device_registry file. However for some reason, these devices get created and they seem to be immediately deleted. In the core.device_registry file it shows as a deleted device:

{
    "data": {
        "deleted_devices": [
            {
                "config_entries": [
                    "binary_sensor.lvrm_door"
                ],
                "connections": [],
                "id": "5fd4c8109e8643b799fa79fab49e22d2",
                "identifiers": [
                    "binary_sensor.lvrm_door"
                ]
            },
TRUNCATED

My only wild guess is that there is some call that maybe updates the device and realizes there is no matching config_entry for these devices and they get deleted.

I may be in over my head here but does anyone have any idea why this is happening?

Thanks
Tom
