Does anyone know the cec command to tell all connected devices that the rpi is shutdown / standby?

Once the RPi is halted how will it send any CEC command? Or are you looking for something that runs as part of boot/shutdown before the RPi reaches its halted state.

http://www.cec-o-matic.com/ says to send a 0x36 message to set everyone to standby. Or do you mean an "inactive source" 0x9D message?
Any language using left-hand whitespace for syntax is ridiculous

Any DMs sent on Twitter will be answered next month.

Any requirement to use a crystal ball or mind reading will result in me ignoring your question.

Hi,

It doesn't need to halt, it just needs to either send an inactive command or change the active source to another device.

This is my current bus information

Code: Select all

CEC bus information
===================
device #0: TV
address:       0.0.0.0
active source: no
vendor:        Panasonic
osd string:    TV
CEC version:   1.3a
power status:  on
language:      eng


device #4: Playback 1
address:       1.1.0.0
active source: no
vendor:        Panasonic
osd string:    CECTester
CEC version:   1.4
power status:  on
language:      eng


device #5: Audio
address:       1.0.0.0
active source: no
vendor:        Unknown
osd string:    HDCVT Main
CEC version:   1.4
power status:  on
language:      ???
this is what happens when I try to set the rpi as the active source
