Update notifications! Core, HACS, Supervisor and Addons

Hi, I’m searching for a solution if a specific log entry is raised in log provider: host under …/hassio/system.
Is there a possibility to build a sensor that goes on if following value is in log?

cdc_acm 2-2:1.0: ttyACM0: USB ACM device

Hi everybody,

I must admit that I haven’t read the complete thread (estimated reading time: 49min - wow :slight_smile: ), so sorry if this has been asked/answered before:

Is it possible to share such an “update solution” as a Blueprint?


It is shared as a package.
just create a package.device_health_notification.yaml file in your config directory and include the following ling in configuration.yaml:

    device_health_notification_pack: !include package.device_health_notification.yaml

Not currently. You can only make a blueprint of an automation and automations can’t run commands on the command line or make http requests directly, both of which are needed to check for updates. Most of this work is sensors which do just that and the only easy way to share a bunch of sensors is a package that you must manually include.

Hopefully someday blueprints can include other config besides automations they depend on. Or even better, make a blueprint of a package itself. Then could just prompt the user for the notifier they want to use and be all set.

Just a basic question as I´m finally looking into https://www.home-assistant.io/integrations/alert/ : alerts can only be created from yaml and therefore HA always needs to be restarted to read new alerts or changes on existing ones, right?

That´s really painful once you´re getting used to the quick “change and test” mode when using automations for notifications. Is there any way to avoid needing to restart HA?

Yea I know, it’s quite a bummer alerts didn’t get made reloadable from the UI as part of WTH month like so many other things. I still really like that they build in nagging reminders and those survive restarts but now I have to weigh the need for that against easy changeability. One notification when the update is available is probably enough, nagging reminders periodically might not be worth the hassle.

Although actually even automations can approximate alerts pretty closely. This nagging reminder blueprint is basically an alert as an automation for all intents and purposes.

A few posts up Hananv shared a package that uses an automation instead of alerts. If you want to switch I’d recommend taking a look at it. Can either bring it in as a base or use at as an example and replace the alerts in mine with an automation like that. Or if you want the nagging reminders then just drop the alerts from the package entirely and make a bunch of copies of the blueprint I linked instead, one per update sensor you want to get notified about.

Hey Folks :slight_smile:

I am also looking for a update status / notfier for my Home Assistant OS - but I read this topic till page 15 and I gave it really up!

I found node-red examples…
The URL “http://supervisor/supervisor/info” dont exist on my network - so the first post cant work for me…

In my opinion: this thread is confusing :frowning:
Is there an easy way to implement ?

If by this you mean you are trying to hit it via curl or something from your laptop then yes that won’t work. That URL only exists within the docker network when you are running supervisor. So HA can hit it since its running from within that docker network but you can’t hit it from your laptop.

Yes. The first post has two packages. The first notifies you of updates to Core, Addons and HACS packages. The second does all that and also adds update notifications for all the other supervisor components (audio, dns, cli, etc.) Pick one and drop it into your config as a package. If you need help understanding how to do that, take a look at the packages doc.

Lol ? I am working with docker since years and never saw an internal communication using http proto :o

Oops didnt recognized the drop down menus in your first post :smiley:
And thank you for your help - But I will test in tommorow… to much headdache lol

If I have questions I will write to you :slight_smile:

Well I can’t say I’m an expert on it but I’m pretty sure that’s all part of what supervisor does. The dev team always says supervisor is more then just a basic docker network. One of the things it does I believe is facilitate intercontainer communication. You can refer to the supervisor container from within the network at http://supervisor, the home assistant container at http://homeassistant, and other addons at http://<addon slug>. Or https for things running that way.

There’s probably lots of other tricks too, I feel like I discover new ones all the time lol.

True I can feel you - welcome in the docker world. Thats a normal feeling as I can say :smiley:

I didnt checked the structure of the core container from home assistant - limited time you know ? :smiley:

EDIT: I Imported your package file -> works great, but unfortunately without HassOS Update notification…
But I found a way to implement it by myself :slight_smile:

cant find the correct thread for my Stats question, so please allow me here, and point me to it if needed…

we have several Stats sensors for all add-ons, and Supervisor and Core, but I can make a Host sensor, like

  - platform: command_line
    name: Stats Host CPU
    command: >
      curl -sSL -H "Authorization: Bearer $SUPERVISOR_TOKEN" http://supervisor/host/stats
    unit_of_measurement: '%'
    value_template: >
    scan_interval: 60
      - data

isn’t this possible, or am I simply using the incorrect path.
thanks for having a look

The available paths for Host in the Supervisor REST API can be found here. I don’t see a /stats (and get a 404 when I try). I think you’re looking for /info as that gives me a response like this:

    "result": "ok",
    "data": {
        "chassis": "embedded",
        "cpe": "cpe:2.3:o:home_assistant:hassos:5.12:*:production:*:*:*:odroid-n2:*",
        "deployment": "production",
        "disk_free": 77.1,
        "disk_total": 113.9,
        "disk_used": 31.1,
        "disk_life_time": 10.0,
        "features": [
        "hostname": "homeassistant",
        "kernel": "5.9.16",
        "operating_system": "Home Assistant OS 5.12"

Although unfortunately I don’t see anything about cpu utilization in there so I’m not sure if there’s a way to get to that. There’s a lot of APIs though, others on host as well as some on hardware. Perhaps that info is somewhere in there?

Alternatively, you saw the system monitor integration right? I use that to get this info on my host currently. If you just want to get at the number that might be easier? Although not sure what other metrics you were hoping for in data, it has a limited set of metrics it exposes.

thanks! I hadn’t seen tat page, and what a nice page it is, with the fold out response values. cool.

yes, I was looking for the memory usage, to have the 3 of them, Host, Core and Supervisor be displayed in a nice graph somehow, probably test it with the new circular apex charts-card …

yes, I do have the system monitor, but am not sure which usage that shows. Is it the total for all 3?

given the fact we doing have anything but used space in the supervisor window:

I am still trying to figure out what’s what… because I also see:

which seem to have no obvious connection with the supervisor panels

Oh ok. So I think system monitor gives you everything from the host itself except CPU temperature. I get that with this sensor, dunno if there’s a better way:

# CPU temperature
- platform: command_line
  name: CPU Temperature
  command: "cat /sys/class/thermal/thermal_zone0/temp"
  unit_of_measurement: "°C"
  value_template: '{{ value | multiply(0.001) | round(1) }}'

For the three boxes up in the supervisor -> system panel, you can get all that data from these 3 endpoints:

http://supervisor/host/info			# Info on disk space
http://supervisor/supervisor/stats	# Info on supervisor CPU/RAM usage
http//supervisor/core/stats			# Info on core CPU/RAM usage

Idk why the first one is /info and the others are /stats but if I throw each of those in curl I see all the info and more being presented in those 5 bar graphs.

Where you got that last card image from (blue one)? Looking great!

thanks, and yes, using the temp sensor too here.
would wish the /hardware/info would do as it advertises… in my instance it outputs a huuuuge page of all possible data, and the displayed output in the docs is from some time ago, pure and simple. If I need to find the USB port for the zwave stick I have to scroll a ridiculous amount of lines…

/misc/info isn’t allowed?

haven’t checked it for a while, so maybe settings in the card-mode or bar card have changed meanwhile. This is still working as it should though :wink:


Was sensor.hacs_updates supposed to be sensor.hacs? Looks like in the HACs documentation that’s the sensor name for updates.

Ah yea, I need to update that. It used to be sensor.hacs_updates but this was originally made a while ago. I believe it changed to sensor.hacs when v1.0 came out since a lot changed at that point.

I still have it as sensor.hacs_updates in my system since I just clicked and changed the entity ID. But I should update it to use the default name as most people will have that.
