Turn off and on Denon/Marantz zones together with the main zone. (link main zone with zone 2 / zone 3, link zones)

Adding your Marantz / Denon to home assistant

Follow the setup steps first, if you have not added your receiver to home assistant yet

Setting up the automations (two)

We will have to do this twice

1. automation to turn off zone2/3 when main turns off
2. automation to turn on zone2/3 when main turns on

Let’s head over to settings, automations, and create a new automation!
