[mythtv-users] Mythwelcome and ACPI wake up

[fb517255 at skynet.be]

Gents,

Thank you all for the great support. As it working I will try to
document everything to help other users.

so first; these are the settings recommended by mythtv (see
http://www.mythtv.org/wiki/index.php/Mythwelcome)

1. Set wakeuptime command: mythshutdown --setwakeup $time
2. Server halt command: mythshutdown --shutdown

Now let's see what those commands are doing;

Command 1: checks if a wake-up time should be set, if yes it will write
to the mythdb the required wake-up fields and after that it will
executes the command mentioned under nvram-wakeup command with the
required time parameter in Unix time stamp.If you don't set those time
values in the DB, mythwelcome will never be able to know that it was a
scheduled wake-up.

In clear, mythshutdown --setwakeup $time executes nvram-wakeup command +
UnixTimeStamp.

Command 2: will check in mythwelcome if you have set a daily wakeup and
if yes it will check if it has to set this as wakeup time (depending on
recordings etc). If it has to set the wakeup time it will use again the
nvram wakeup command with the unixtimestamp. After timestamps are set it
will execute the command: Command to Shutdown.

In clear, mythshutdown --shutdown executes nvram-wakeup command
UnixTimeStamp + Command to shutdown.

If I explained everything correctly you should have found that the key
to make everything work is the script you put in nvram-wakeup command.

You can use the MythWakeSet script mentioned in the wiki for that.
I hope this is clear, if not don't hesitate to let me know.


PS: A good tip is to execute both command with the verbose switch. You
will set everything the command is trying to do.

regards,

Matthews
