I had the automation that went "all #Shelly plugs on" and "all plugs off". It worked from an automation perspective. But this led to the Apple TV booting without connecting to the TV; which stayed asleep. That stinks because one needs to then use the TV remote controller to turn it on and switch to HDMI.
Hopefully, #HomeAssistant provides a "delay" object that can be included in the automation.
It is now set as "power on TV, power on Soundbar, wait 2 seconds, power on Apple TV". And everything works as expected by us, Muggles!
