Locative device trackers disappear after restarting HA

[davidbb]

Home Assistant release with the issue:

arch	amd64
dev	false
docker	false
hassio	false
os_name	FreeBSD
os_version	11.2-STABLE
python_version	3.7.4
timezone	America/Toronto
version	0.101.0
virtualenv	false

Last working Home Assistant release (if known):
Unsure. Did not use Locative prior to the migration to Integrations config.

Integration:

Locative

Description of problem:
After creating a webhook through the Locative integration config flow, my devices are able to submit webhooks successfully. For each device sending POST requests to the webhook, a new device_tracker is created in HA. These device trackers can be linked to a person to track their state in HA.

The problem is that when HA is restarted, the device trackers that had been previously created no longer exist. This causes Persons to be shown as "unknown" (or "UNK" in badges). I've confirmed that the device trackers get re-created when the next POST request is sent to the webhook. I've also noticed that the entity registry does not list Locative device trackers.

Ideally, device trackers would persist after restarts and should be deleted manually if no longer needed. The state of the device tracker at HA startup should be the last state recorded prior to HA shutdown.

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

No configuration.yaml because Locative is configured through the Integrations page

Traceback (if applicable):

Same problem here. The created device_tracker is not shown in the locative integration. Its empty

Same issue here. Any solutions?

If the locative device has a unique id it's possible to implement the same solution as done for gpslogger:

This issue is a feature request and not really a bug as the integration is working according to current implementation. I'll close here now.

@MartinHjelmare Why closed?

This issue is a feature request and not really a bug

It is an abnormal functionality that was broken several versions ago and should be fixed.

[MartinHjelmare]

It's a feature request. We don't track feature requests in our issue tracker.

I've outlined the solution above. A PR with that is welcome.
