I'm seeing frequent logs reporting unknown message types 50, 53, 56, and 59, which don't have entries in LXProtocolTypes.h. I only have original LIFX bulbs on the network (no LIFX White 800 lights) so it must be something else that the bulbs are sending out that's new. Hopefully we'll get a LIFXKit update soon? It doesn't crash my app (at least in this case) but at times it really fills up the logs.
ERROR: unknown message type '50'. The appropriate class may need to be registered in +[LFXMessage messageWithMessageData:]
