# Custom Services

Some service can use a specific a component that provides some extra features by adding a `type` key to the service yaml
configuration and, where applicable, an apikey. Note that config.yml is exposed at /assets/config.yml via HTTP and any
apikey included in the configuration file is exposed to anyone who can access the homer instance. Only include an apikey
if your homer instance is secured behind some form of authentication or access restriction.

Available services are in `src/components/`. Here is an overview of all custom services that are available
within Homer:

## Uptime Kuma

Using the Uptime Kuma service you can display info about your instance uptime right on your Homer dashboard.

The following configuration is available for the UptimeKuma service. Needs v1.13.1 or later because of the change in APIs due to [multiple status pages support](https://github.com/louislam/uptime-kuma/releases/tag/1.13.1).

```yaml
- name: "Uptime Kuma"
  logo: "assets/tools/sample.png"
  # subtitle: "A fancy self-hosted monitoring tool" # optional, if no subtitle is defined, Uptime Kuma incidents, if any, will be shown

  url: "http://192.168.0.151:8181"
  type: "Tautulli"
  apikey: "MY-SUPER-SECRET-API-KEY"
```

Because the service type and link don't necessarily have to match, you could
even make the service type Tautulli on your Plex card and provide a separate
endpoint pointing to Tautulli!

```yaml
- name: "Plex"
  logo: "assets/tools/sample.png"
  url: "http://192.168.0.151:32400/web" # Plex
  endpoint: "http://192.168.0.151:8181" # Tautulli
  type: "Tautulli"
  apikey: "MY-SUPER-SECRET-API-KEY"
```

## Mealie

First off make sure to remove an existing `subtitle` as it will take precedence if set. 
Setting `type: "Mealie"` will then show the number of recipes Mealie is keeping organized or the planned meal for today if one is planned. You will have to set an API key in the field `apikey` which can be created in your Mealie installation.

## Healthchecks

This service displays information about the configured status checks from the Healthchecks application.
Two lines are needed in the config.yml :

```yaml
  type: "Healthchecks"
  apikey: "01234deb70424befb1f4ef6a23456789"
```

The url must be the root url of the Healthchecks application.
The Healthchecks API key can be found in Settings > API Access > API key (read-only). The key is needed to access Healthchecks API.

## Proxmox

This service displays status information of a Proxmox node (VMs running and disk, memory and cpu used). It uses the proxmox API and [API Tokens](https://pve.proxmox.com/pve-docs/pveum-plain.html) for authorization so you need to generate one to set in the yaml config. You can set it up in Proxmox under Permissions > API Tokens. You also need to know the realm the user of the API Token is assigned to (by default pam).

The API Token (or the user asigned to that token if not separated permissions is checked) are this:

| Path               | Permission | Comments                                                          |
| ------------------ | ---------- |                                                                   |
| /nodes/<your-node> | Sys.Audit  |                                                                   |
| /vms/<id-vm>       | VM.Audit   | You need to have this permission on any VM you want to be counted |

It is highly recommended that you create and API Token with only these permissions on a read-only mode.

If you get errors, they will be shown on browser's dev console. Main issues tend to be CORS related as Proxmox does not include CORS headers and you have to desploy it behind a reverse proxy and make the proxy add this headers.

Configuration example:

```yaml
- name: "Proxmox - Node"
  logo: "https://www.google.com/url?sa=i&url=https%3A%2F%2Fgithub.com%2FandOTP%2FandOTP%2Fissues%2F337&psig=AOvVaw2YKVuEUIBeTUikr7kAjm8D&ust=1665323538747000&source=images&cd=vfe&ved=0CAkQjRxqFwoTCPCTruLj0PoCFQAAAAAdAAAAABAN"
  type: "Proxmox"
  url: "https://your.proxmox.server"
  node: "your-node-name"
  warning_value: 50
  danger_value: 80
  api_token: "PVEAPIToken=root@pam!your-api-token-name=your-api-token-key"
```
