url = "http://$host/off" url = "http://$host/off"
delay = 300 delay = 300

## Parameters
To remove the need to hard code ip addresses or host names, you can configure parameters to query for an ip address and
use it in a query or url.
### MDNS
```toml
params.host = { type = "mdns", service = "_switch-http._tcp.local", host = "switch2" }
```
Will attempt to lookup a host advertising itself under the `_switch-http._tcp.local` service with host name `switch2`
and return the ip address and port of the host.
### Service
```toml
params.host = { type = "service", file = "services.json", key = "hostname", value = "switch2" }
```
Will look for a host in a json file in [prometheus' file based service discovery format](https://prometheus.io/docs/guides/file-sd/)
for an entry containing the label `hostname` with value `switch2` and return the first target.
