Looking through the LAN API Documentation, it appears that sending a light message with type 120
(GetInfrared
) will cause the light to respond with a 121
(StateInfrared
) if, and only if, the 120
message includes a res_required
flag. I have confirmed that the light will not send the StateInfrared
message if this flag is not set. But this flag is not necessary to receive a response for any other Get
message type, as one would assume, since sending a Get
message implies that a response is required.
So what gives? Why is GetInfrared
so special?
