Describe the bug

I have duplicated sensors for each specified object, eg:- "sensor.frontdoor_person" and "sensor.frontdoor_person_2"

I'm guessing this could be because you have a camera name 'frontdoor' and a zone called 'FrontDoor'. One sensor is referring to objects for the camera, the other is referring to objects for the zone. Try renaming one of them.

[Coolie1101]

camera name 'frontdoor' and a zone called 'FrontDoor'

Indeed I do, had no idea sensors were created for the camera itself, thanks.

[Coolie1101]

Hey @dermotduffy, any idea how to remove/delete old zones?

[dermotduffy]

Review my comments on this issue which give a number of options: https://github.com/blakeblackshear/frigate-hass-integration/issues/140

[Coolie1101]

Already deleted the entities, but the zones still show up under devices.

[dermotduffy]

Devices with no entities are (IIRC) automatically garbage collected after some time. If you don't want to wait you could manually remove them from .storage/core.device_registry after you take a backup.

[Coolie1101]

I went with the latter, works so far.

Just out of curiosity, how long does it normally take to be automatically removed?, FYI, been like that since the first day I installed a few weeks ago, and was testing out different options to get an understanding of how things work.

[dermotduffy]

Apologies, not sure. In reality, the real issue is with this integration. It should automatically remove cameras/zone that are associated with the integration but no longer 'live' -- that's just not implemented yet.

[dermotduffy]

... so lets keep this bug to reflect that feature gap.

[Coolie1101]

No worries, thanks for your help.

[Coolie1101]

Amazing, would this also take care of the existing unused entities after updating?

[dermotduffy]

@Coolie1101 only unused entities that are associated with a Frigate device. Frigate devices were introduced from v1.1.0 onwards (~July). Crufty entities created prior to that would not be cleaned by this functionality.

[Coolie1101]

So orpaned entities from within the past couple days would get purged after the new release?

I'm only asking because I disabled (removed from config) a couple zones which still show up as unavailable.

[dermotduffy]

That's a good test. Yes, as long as were running with an integration >= v1.1.0 when you first added those zones, then the next release should clean that up for you without you needing to do anything.

[Coolie1101]

Awesome, definitely newer than v1.1.0, as I only started using Frigate a couple weeks ago.

Also the link to the doc link in the integration links "https://github.com/blakeblackshear/frigate" as appose to "https://github.com/blakeblackshear/frigate-hass-integration"

[Coolie1101]

then the next release should clean that up for you without you needing to do anything.

I mite be wrong, but this doesn't seem to be the case, I am now on version 2.2.2/0.11.0-cbf26e0 and still have duplicated entities.
