Hello,
Slightly off-topic here but please note that SamsungTV calls home (viz. cdn.samsungcloudsolution.com) every FIVE seconds. I have openHAB working with SamsungTV (to get sufficient details including current channel, volume level, etc.) but your question has spurred me into digging further with Node-RED for the interface. I don't know whether the openHAB can share their interface details but a simple ping node would be my first start.
One other point, SamsungTV identifies itself as localhost (sic) and one needs the API to change it to something else that some routers will not complain about.
King regards.
