Just a FYI, I think it works now, I had to increase the total delays to 14 seconds.
TV power I a gave it 4s
Dune Homatics Box power toggle I gave it 6s
Then I do the HDMI toggle and give another 2s
Then I toggle the dune's home page command
Then finally I do another HDMI 4
They don't seem to be accurate though, the animation finishes way faster than 14 seconds. If I count 1001 etc to 1014 the animation finish in like 4 or 5 seconds. Not sure if it's supposed to keep displaying thru the whole macro.
