WTH can't I delete old and unused entities?

Month of "What the heck?!"
1

(I think I know the answer to this one - makes re-adding stuff complicated)

But I tried to get my partner to set up a trial HA instance when I saw it was WTH month and this quickly arose - I remember the same problem when I first started.

That being said. I once re-added a mobile app and still have 66 entities there and hidden from the last one.

All unused entities can be deleted. If they are orphaned, an delete button appears on each entity.

Also, when looking at the table/list of entities you can filter on those and multi select them, deleting them at bulk.

@frenck How do you filter on these entities in the entities list?

I have added another question (WTH why can't we filter entities and devices lists) asking for exactly that ability.
I have several “orphaned” entities which I am unable to delete - not sure if it is maybe because they are referenced in a display somewhere so not “unused”.

From memory this was changed a few months back, so selecting an unwanted entity now results in a “This entity does not have a unique ID, therefore its settings cannot be managed from the UI. " error message. The " Customizing entities” page which is linked to the error message assumes that the entity can be edited.

I can delete the device, but the extra entities which I created with it do not get removed. Recreating the device results in multiple entities with the same name and a trailing sequence number.

So, how can we now delete unused entities ?

There are file in the config/.storage where those data are saved.
Like core.entities_registry
But handle with care!

Sadly, when I look at my file, I even see empty ‘entities’. Looks a bit messy. They should ,perhaps during startup, remove those ‘empty’ entities, and clean up that file…

Thanks Stefan,

TL;DR: I was actually creating the same entity name in 2 places.

In my /config/.storage/core.entity_registry I see only the new entities (with entity_id has a _2 suffix), but not the other entries.

      {
        "aliases": [],
        "area_id": null,
        "capabilities": null,
        "config_entry_id": "cbf83fc72f1d75101383cb5411318600",
        "device_class": null,
        "device_id": "7efcf2c32fdd50b5a981310fd7c1fcc8",
        "disabled_by": null,
        "entity_category": null,
        "entity_id": "sensor.pc191ha_107_voltage_2",
        "hidden_by": null,
        "icon": null,
        "id": "2bf39d2f06251d05adc8bb99afb86b1c",
        "has_entity_name": false,
        "name": null,
        "options": {},
        "original_device_class": "voltage",
        "original_icon": null,
        "original_name": "pc191ha-107_voltage",
        "platform": "localtuya",
        "supported_features": 0,
        "translation_key": null,
        "unique_id": "local_7lmHRoyxlLzIeXTRCFo8_20",
        "unit_of_measurement": "V"
      },
      {
        "aliases": [],
        "area_id": null,
        "capabilities": {
          "options": [
            "on",
            "off",
            "memory"
          ]
        },

Are you perhaps thinking of the “deleted_devices” section in core.device_registry ?

DOH !!! bangs head !

I can’t delete the entities, because they are created in configuration.yaml ! I followed the instructions in LocalTuya integration documentation for creating sensors from the attributes returned by the switch, like so …

      #  
      pc191ha_107_voltage:
        value_template: >-
          {{ float(state_attr('switch.pc191ha_107', 'voltage') | default(0, true)) }}
        unit_of_measurement: 'V'
      pc191ha_107_current:
        value_template: >-
          {{ float(state_attr('switch.pc191ha_107', 'current') | default(0, true)) }}
        unit_of_measurement: 'mA'
      pc191ha_107_current_consumption:
        value_template: >-
          {{ float(state_attr('switch.pc191ha_107', 'current_consumption') | default(0, true)) / 1000 | round(1) }}
        unit_of_measurement: 'W'

For a while i was also adding number entities for current, voltage when adding the device in the LocalTuya integration.

And I just discovered that the localTuya Integration now allows adding “sensor” entities when creating the device … so guess what I was trying (without commenting out the section in configuration.yaml).
