In my case, I have these commands, just replace the device name:
“turn on ac1715”
“turn off ac1715”
“turn on auto mode on ac1715”
“turn on sleep mode for ac1715”
IIRC I had the same command for sleep mode, but had to change it, because it didn’t work each time.
same problem here.
also tried to scan for open ports on the device, but found none. I think philips might have killed support for local access.
