Do you have a message triggered off the aux zone? This has long been the recommendation from HAI if you want an aux zone to display on the keypad when not ready, this works for Haiku as well, unfortunately Haiku also ALWAYS beeps messages even if displayed with no beep, it will also push them unless sent no beep and no led.
I know my rain sensor is an aux zone but displays a message with led but no beep. The rain sensor will beep in Haiku and if I have push enabled for message will push beep me as well, very annoying. All I want is the rain message to be displayed with a blinking LED on keypads and silently on Haiku status screen. Nothing like pulling up Haiku when I'm going to bed only to have it make a loud beep because the rain sensor triggered 4 hours earlier and waking up the wife...
Aux zone are for automation, it supposed to be up to the programmer what they do, no default behavior, I am glad Haiku went to the designed behavior sometime back (except for the scrolling messages), now the message behavior just needs to be tweaked to follow HAI's design as well.
