|Parameter|Description|
|--|--|
|Name|Name of node on flow|
|Topic Prefix|Prefix will be added to topic property on output message payload|
|Listen Port|Port of UDP Server to listen on. Useful on multiple devices|

## Connectivity
To capture the published data from your SysteComfort II device you have to redirect the traffic on your local network. If you have a local DNS Forwarder you can just create a static host override. The domain `pradigma.remoteportal.de` needs to be resolved to your internal Node-RED ip address.
