Control volume with switch (Aqara OPPLE / Denon AVR)

hello, i want control my denon avr (volume up and down) with my
Aqara OPPLE.

here is my node:

unfortunately the volume is not changed properly. HA only reacts now and then

I guess we need a bit more info about what you’ve already done and the expected behavior.

Volume doesn’t change every time you press a button?

You can use debug nodes to see exactly where signals get cancelled.
