Hello,

I have connected VU Ultimo 4K hdmi output with onkyo hdmi port and it's output with Samsung TV Set HDMI Input. TV is able to detect both AV receiver and tuner CEC and I am able to control TV and VU, change volume so CEC messages are going back and forth, so hdmi port numbers are set correctly in vu configuration

However the only problem is when av receiver is put into sleep mode - it forwards video (there is a special CEC mode active standby) but neither tv nor vu is able to wake onkyo up and make it's speakers work, and I have to wake it up manually with its remote.

Is there any recommended setting for this configuration? I've enabled loggging cec on vu but cannot track root cause. Is there any recommended approach how to verify AV response to VU wakeup?

There is no cec-client installed in default VTi image - is there any package which contains this applicaction?

I am not sure either which command should be waking AV receiver up when VU wakes up from standby? How can I diagnose what fails during wakeup?

you can download the plugin here:

thank you for the link. As far as I can see my plugin is much newer - I have installed from VTi image:
enigma2-plugin-systemplugins-hdmicec (1.8-r0)
and uploaded ipk in your link is
enigma2-plugin-systemplugins-hdmicec_1.4-r0_all.ipk

In OnScreenMenu / Extension (or Plugins ?) / VTI HDMI CEC
is an Option A/V Receiver On , have you tried this ?

Plugin is installed and working:
menu "A/V-Receiver volume up:" works fine, cec log shows:
(UserControl VolumeUp, Set System Audio Mode)
and volume changes correctly.
menu "A/V-Receiver power on:" sends
(UserControl PowerOn)

which is completly ignored by onkyo A/V and it does not wake up.
So onkyo receives correctly some messages on logical address 5, and other ignores.
From log it's difficult to say if message was ACKed or not, but CEC Feature Abort message was not sent.

When A/V is turned on from it's own remote:
(ReportPhysicalAddress, DeviceVendorId)
which is fairly interesting as these opcodes should have parameters printed in log. Is cec logging corrupt here?

When A/V is turned off from it's own remote(standby):
(Set System Audio Mode)
I tried different combination of "VU+ on from standby" but they are sending the same commands do wake up onkyo just in a different order and all are ignored by it.
For diagnostics I would like to use cec-client tool to send binary cec messages directly through hdmi, but cannot find this tool for ultimo 4K

I have noticed that sometimes volume control from TV remote and/or VU+ remote in TV mode stops working with onkyo AV receiver until full poweroff.
So disconnecting from power supply helps in a different case which means there might be a software issue either on samsung or onkyo side.

Anyway I've made a temporary workaround for now: VU+ calls STANDBY_LEAVE.sh from /etc/enigma2/events and runs remotely onkyo-oiscp via tcp connection.
I cannot continue until i'll find out what exactly cec commands onkyo expects to wake up
