Duplicate push notification

[parautenbach]

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.

[parautenbach]

Just posting a quick update: It's still happening (HA 2022.6.6 and iOS 2022.3), but I did notice that clearing one of the two notifications actually clears both. Not sure if it's important, but mentioning it nonetheless. I'm guessing it would only happen if iOS think it's the same notification.

[parautenbach]

Another bit of info that might help: I noticed that when I clear the one notification, it removes both. Probably just confirms that it is an identical notification (e.g. if there's an underlying unique ID being used, both have the same ID).

[ryanhindinger]

I don’t have the logs but I am seeing this exact issue on 2022.7–running in a VM Box. Clearing one notification clears the other automatically and it’s only happening with some notifications.

[parautenbach]

Hopefully another instance of this issue can help us debug this pesky issue. Which mobile client (and version) are you seeing this on? Android or iOS?

[ryanhindinger]

I am seeing this on iOS v15.5 with Home Assistant companion app version 2022.3 installed. Not sure if it helps but my notifications are all being fired out of NodeRed—including the ones that are duplicating and those that aren’t.

[parautenbach]

Could you share more about your settings? Do you have local push enabled?

[creeve4]

I also occasionally get duplicate notifications on my Android devices (mine and my wife's Pixel phones). I am not using Local Push.

Home Assistant 2022.7.6

Below is the automation from which the notifications originate. I am happy to provide additional information as needed.

[caladrien]

Same here. I'm running 3 diffret Android device with curret versio of the app. All receiving notifications duplicates.

SS from noti history.

Edit: doesn't make a different if I'm on or off wifi.

[parautenbach]

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.

RPReplay_Final1671893186.mov

[caladrien]

I solved it for me. The reason seams to be an defective cache of the android home assistant app. I received as many notifications as I had logged in with different credentials in the app. In the beginning of home assistant I was playing around with users so lot. Clearing the apps' cache and data left me with only one notification.

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates.
Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment 👍

Still an issue.

Still an issue.

Try to reset Push ID. It helped me.

Thanks, I see it hasn't been mentioned, but unfortunately it doesn't fix this specific issue.

I am having the same issue of duplicate or occasionally quadruple notifications.

My Home Assistant version is 2023.8.4 and the iOS app is on the latest version: 2023.460.

I have followed a few steps that were recommended in the original forum thread as well as some solutions mentioned here on Github- without any success. My attempts to resolve this included:

1. Checking my automation yaml for duplicate entries.
2. Companion App: Notifications > Reset 'Push ID'
3. Companion App: Debugging > Reset Frontend Cache
4. Companion App: Debugging > Reset
5. Ensured automation mode is set to single- added a delay to my automation to avoid it being executed more than once.
6. Companion App: Server Settings > Disable Local Push

. The following is my automation:

alias: Notification - Entrance Door Sensor - Open
description: ""
trigger:
  - platform: mqtt
    topic: zigbee2mqtt/hallway.doorsensor
    value_template: "{{value_json.contact}}"
    payload: false
condition: []
action:
  - service: notify.mobile_app_11pro
    data:
      title: Home
      message: Door Opened
  - delay:
      hours: 0
      minutes: 1
      seconds: 0
      milliseconds: 0
mode: single

I am also coming across the following message in my HA logs:

To give a bit more context, the issue started happening for me when I duplicated the above existing automation via the iOS app, in order to create a new automation for the door sensor. The new automation does not include sending a notification- it simply plays some media, when the door is opened. I tried disabling this new automation to see if the issue would persist and unfortunately it does. I also double checked the mode of both automations because I wanted to make sure that these are set to "single".

Finally, an interesting observation: when executing the automation via the app using the "run" function, I only receive a single notification.

In case there is more information required, I'd be happy to provide this.

Thanks for your help!

[AndyPook]

Getting the same issues on Android...
I'm creating the notification via call_service over the websocket api to the local instance. So pretty sure it's not a "broken" automation

Seeing this is the log

the server_id part caught my eye
I do have nabucasa's HA Cloud connected. A bit naïve... is that the other "server"

Maybe a clue... maybe not

Ah, thanks for capturing that. It's indeed still an issue for on iOS too. I haven't been able to catch the information you have. Perhaps the iOS logs are different.

You might want to remove/obfuscate those webhook IDs though.

[AndyPook]

FYI... my version of this "problem" has been resolved

It turns out that there was a reference to an old phone. Somehow this resulted in the notification to both phones. But as the old one no longer exists it was redirected to the new phone. (or something like that)
Hard to replicate now I only have a single phone.

(you can search /config/.storage/core.entity_registration for your various phone names to see if this is the thing for you)
Managed to find some references to the old phone, found the offending items, deleted.
Now I only get a single notification

It still happens with varying degrees: Sometimes many notifications will be duplicated, sometimes only one or two (over the span of a day).
