This is a flow where a press on my Tap Dial button 4 does:

• Set the input source on my Marantz AVR to Apple TV
• Set the input source on my Samsung TV to HDMI (The Marantz AVR)
• If the Philips Hue Sync Box is not on:
  • Power on Philips Hue Sync Box
  • Set the input source on Philips Sync Box to HDMI
• Starts the Sync
