Sample WatchDog
With msg.setGatewayConfig, you can change the IP, Port, Physical Address and so on of your KNX/IP Interface or Router, previously set in the Config-Node
The Config-Node will change the settings and reconnect with new parameters.
ALL parameters are OPTIONAL
Please use the WatchDog node for that.
// IP: IP of your KNX/IP Router or Interface
// Port: Port of your KNX/IP Router or Interface
// PhysicalAddress: Physical address your KNX/IP Router or Interface (this is not a Group Address, this is a physical address indicating the physical device in your KNX installation), Protocol.
// BindToEthernetInterface: "Auto" (for automatic detection) or the ethernet interface name, for example "en0".
// Protocol: "TunnelUDP" or "TunnelTCP" or "Multicast"
// All these parameters are optional
msg.setGatewayConfig={IP:"224.0.23.12",Port:3671,PhysicalAddress:"15.15.1",BindToEthernetInterface:"Auto", Protocol:"Multicast"};

You can start/stop the watchdog manually, or you can switch to a backup KNX/IP Router in case the main fails.
Please read the WatchDog related Wiki (points 7, 8, and 9 on the right wiki navigation's panel).
In this sandbox example, you can learn how to manually start/stop the watchdog, how to manually change the knx-ultimate gateway configuration and how to send, for example, an email in case of KNX connection problem and how to, for example, change the KNX Gateway configuration to a backup Gateway.
