#ssdp_response?(resp) ⇒ Boolean

Ensure we’re only getting responses from a Philips Hue bridge. The Hue Bridge tends to be obnoxious and announce itself on any SSDP SSDP request, so we assume that we may encounter other obnoxious gear as well…

Returns:

  • (Boolean)

#usn_to_id(usn) ⇒ Object

TODO: With all the hassle around ID and the fact that I’m essentially TODO: coercing it down to just MAC address.… Just use the damned IP TODO: or MAC!
