Denon avr (avr-x8500ha)

Does anyone know the command to set the subwoofer level on a Dual Sub Denon AVR?

When searching online, I came across:

action: denonavr.get_command
target:
entity_id: media_player.denon_avr_x8500h_2
data:
command: “/goform/formiPhoneAppDirect.xml?CVSW%20500”

Where the 500 at the end apparently means 0dB

And while the execution of this command presents a green check, it has no effect on Subwoofer 1, or Subwoofer 2.

Thanks

Try this instead. It’s what I use on my x1800h
/goform/formiPhoneAppDirect.xml?PSSWL XX
where XX is 38 to 62. 50 = 0dB

For subwoofer 2 use PSSWL2

Tried it along with a few variations like using %20 instead of the space, but still no luck. The command goes through but the receiver doesn’t seem to acknowledge anything happening.

If I open the web interface at IP:port/audio/audio.html# And inspect the network traffic, I see some data related to -451764083904267

(This form is stripping the formatting so it’s not showing what I’m pasting.)

Less_Than SubwooferLevel2 Greater_Than45Less_Than/SubwooferLevel2GreaterThan#

I imagine there is probably an alternate way to send these commands, I just haven’t had a ton of time to experiment, was hoping there would be a simple string I could use.

I see that you used entity_id:media_player.denon_avr_x8500h_2
Make sure that this is the entity id of the AVR and not the HEOS entity id. Also, don’t use quotes around the command
/goform/formiPhoneAppDirect.xml?PSSWL 50

Good luck
