I have a projector (JVC x5500) which is stupid. It blocks remote control input for several seconds when the HDMI signal changes. So I need the AVR and HTPC to turn off after the projector. There for I have put it first in the list
But my Harmony does not wait for the Projector to finish. It shuts down the AVR right away blocking my projector from shutting down.
I tried to explicitly do the shutdown sequence and then add a wait. But it turns out that the Harmony app filters away the shutdown buttons.
