# Home assistant add-on: changedetection.io
|
||
|
||
|
||
I maintain this and other Home Assistant add-ons in my free time: keeping up with upstream changes, HA changes, and testing on real hardware takes a lot of time (and some money). I use around 5-10 of my >110 addons so regularly I install test machines (and purchase some test services such as vpn) that I don't use myself to troubleshoot and improve the addons
|
||
|
||
If this add-on saves you time or makes your setup easier, I would be very grateful for your support!

## About
|
||
|
||
[Changedetection.io](https://github.com/dgtlmoon/changedetection.io) provides free, open-source web page monitoring, notification and change detection.
|
||
|
||
This addon is based on the [docker image](https://github.com/linuxserver/docker-changedetection.io) from linuxserver.io.
|
||
|
||
## Configuration
|
||
|
||
Use the add-on `env_vars` option to pass extra environment variables (uppercase or lowercase names). See https://github.com/alexbelgium/hassio-addons/wiki/Add-Environment-variables-to-your-Addon-2 for details.
|
||
|
||
### Main app
|
||
|
||
Web UI can be found at `<your-ip>:5000`, also accessible from the add-on page.
|
||
|
||
#### Sidebar shortcut
|
||
|
||
You can add a shortcut pointing to your Changedetection.io instance with the following steps:
|
||
1. Go to <kbd>⚙ Settings</kbd> > <kbd>Dashboards</kbd>
|
||
2. Click <kbd>➕ Add Dashboard</kbd> at the bottom corner
|
||
3. Select the <kbd>Webpage</kbd> option, and paste the Web UI URL you got from the add-on page.
|
||
4. Fill in the title for the sidebar item, an icon (suggestion: `mdi:vector-difference`), and a **relative URL** for that panel (e.g. `change-detection`). Lastly, confirm it.
|
||
|
||
### Options
|
||
|
||
| Option | Type | Default | Description |
|
||
|--------|------|---------|-------------|
|
||
| `PGID` | int | `0` | Group ID for file permissions |
|
||
| `PUID` | int | `0` | User ID for file permissions |
|
||
| `TZ` | str | | Timezone (e.g., `Europe/London`) |
|
||
| `BASE_URL` | str | | Full URL when running behind reverse proxy |
|
||
| `TIMEOUT` | int | `60000` | Request timeout in milliseconds |
|
||
|
||
### Example Configuration
|
||
|
||
```yaml
|
||
PGID: 0
|
||
PUID: 0
|
||
TZ: "Europe/London"
|
||
BASE_URL: "https://changedetection.mydomain.com"
|
||
TIMEOUT: 60000
|
||
```
|
||
|
||
### Connect to browserless Chrome (from @RhysMcW)
|
||
|
||
In HA, use the File Editor add-on (or Filebrowser) and edit the Changedetection.io config file at `/homeassistant/addons_config/changedetection.io/config.yaml`.
|
||
|
||
Add the following line to the end of it:
|
||
```yaml
|
||
PLAYWRIGHT_DRIVER_URL: ws://2937404c-browserless-chrome:3000/chromium?headless=true&blockAds=true&stealth=true
|
||
```
|
||
|
||
Remember to add a blank line at the end of the file too according to yaml requirements.
|
||
|
||
The `2937404c-browserless-chrome` hostname is displayed in the UI, on the Browserless Chromium addon page:
|
||
|
||
|
||
You can also fetch it:
|
||
* By using SSH and running `docker exec -i hassio_dns cat "/config/hosts"`
|
||
* From the CLI in HA, using arp
|
||
* You should also be able to use your HA IP address.
|
||
|
||
Then restart the Changedetection.io add-on - after that you can use the browser options in Changedetection.io.
|
||
|
||

||

||

|
||

|
||
1. Click the `Save` button to store your configuration.
|
||
1. Start the add-on.
