Duplicate push notification

The problem

I have a fairly simply automation that sometimes results in a duplicate notification. It’s not the only one that exhibits this behaviour, but for simplicity of debugging the issue I’m focusing on only this one.

- alias: "Notify If New Backup Found"
  trigger:
    - platform: state
      entity_id: sensor.last_backup
  mode: single
  condition:
    condition: template
    value_template: >-
      {% set last_backup = states('sensor.last_backup') | as_datetime %}
      {{ ((utcnow() - last_backup).seconds) < 60 }}
  action:
    - service: notify.mobile_app_ceres
      data:
        title: "System"
        message: "A new Home Assistant backup was made."
        data:
          group: "system-backup"
          url: homeassistant://navigate/lovelace/devices

I logged this issue the first time in March on the forum in case it was an issue on my side. After some assistance from @zacwest it seems like I should report this as a bug.

Zac made a few suggestions, among which to include a random number to establish if it is indeed a duplicate notification and not simply a second notification due to some other issue.

I was already sure at the start that there isn’t a duplicate event or state change – at least not what could be seen via the UI tools.

When I first logged this I was on 2022.2.9. I’m now on 2022.5.4. I keep my iOS companion app up to date all the time.

This is what the duplicate notification looks like:

This seems to be the key to the issue:

2022-05-20 17:56:01.807 [Info] [main] [PushProvider.swift:163] localPushManager(_:didReceiveRemoteNotification:) > failed: notCommand

It seems like the local push fails and then the notification gets sent externally.

I think the notable error is actually:

2022-05-20 17:56:01.808 [Info] [hakit-work-queue] [Environment.swift:71] init() > WebSocket: Received: result failure HARequestIdentifier(rawValue: 2138): external(HAKit.HAError.ExternalError(code: “not_found”, message: “Push notification channel not found”)) via {“id”:2138,“type”:“result”,“success”:false,“error”:{“code”:“not_found”,“message”:“Push notification channel not found”}}

It seems like the confirmation code response handler is having an issue finding the pending response, but it’s also still doing the 10 second wait and firing through the HTTP call, making me think it’s failing to add the “cancel this retry” value to the dictionary.

This is still an ongoing issue. I’ve even had a case recently where the notification showed in triplicate. It really is the same notification, as was indicated by the logs before, but also since one can see in this screen capture chat clearing the one clears them all.
