I recently bought the Aquara Cube and have been playing around with different things it can do. I mostly got it to control volume on my Denon A/V receiver. I am using node red to make the automations and I have volume up and volume down working. However, I am running into a road block trying to get the volume_mute command to work properly. In Node Red, i am getting an error saying I need the key “is_volume_muted” I have read several threads that go over a button card, scripts, etc. but none of them explain how to make the mute function work in node red, or where I can put the “key” in node red to make this work? Is there a way to make this work in Node Red?

In the data field, you need to set is_volume_muted to true or false.
{"is_volume_muted": true}
