Changedetection.io add-on request

Feature Requests
1

Hello,

I would like to have an add-on for changedetection.io (Github link).
I checked the tutorial on how to make it, but it is just a bit above my current ability.
The docker container can be found here: https://hub.docker.com/r/dgtlmoon/changedetection.io
Somebody out there that would like to build this?

Thanks in advance!
Kind regards,
Boudewijn

You should be able to use the RSS url and a standard RSS integration (see feedreader in the HA core docs). The RSS url is found by clicking the orange RSS button on your changedetection.io instance:

I am not 100% sure, but I think the RSS feed can get the notifications from “a change” from Changedetection into HA. I want to self host url change detection service as a whole.

@michelebossa any progress?

The feedreader RSS integration will work fine, but will have a polling interval and therefore a delay.

ChangeDetection uses Apprise notifications, so another option is to configure a notification of type hassio://, see the documentation here (https://github.com/caronc/apprise/wiki/Notify_homeassistant).
It creates a “persistent notification” and therefore an event, which HA can listen for, clear, and then take any action you want via an automation.
Here’s the result of a test notification I sent:

{
    "event_type": "call_service",
    "data": {
        "domain": "persistent_notification",
        "service": "create",
        "service_data": {
            "title": "ChangeDetection Alert",
            "message": "Change Detection (Test from changedetection.io!) has changed.",
            "notification_id": "65a58b08-e018-43a8-9cb3-e8bbe67caedc"
        }
    },
    "origin": "LOCAL",
    "time_fired": "2021-10-25T08:21:56.796650+00:00",
    "context": {
        "id": "dfa18ddc679245ee11a6954e11a02381",
        "parent_id": null,
        "user_id": "7804bba3743643119860e6731f0c7082"
    }
}

The Apprise engine can also generate IFTTT notification events (see https://github.com/caronc/apprise/wiki/Notify_ifttt). I don’t have an IFTTT webhook server installed in my HA to demonstrate, but it would be trivial to do so.

There’s no need for a formal integration.

How will this detect a change of a website?

Bumping this request as I could use this myself. To be clear: the request is for an add-on that would incorporate the self-hosted changedetection.io service, not just notifications from the paid subscription service.

Awesome!
Did not try it yet, but it looks alright.
Direct link to add-on:

I also found it at GitHub - alexbelgium/hassio-addons: My homeassistant addons - this repo has a looooot of other interesting add-ons.

The only downside is a missing panel to access ChangeDetection’s interface - but I got it solved by adding a web page panel via Settings > Dashboards. Not sure if that other add-on would have that done for you.
