sagetv power management

[trueno]

I suppose this is one part question, one part feature request,

Is it possible for sagetv to wake up a suspended computer in the event that it is suspended before a recording is scheduled to take place?

The windows scheduler automatically wakes up a suspended pc when a task is to be run.. it could be as easy as automatically adding a "dummy" item to the windows scheduler for each recording.

thanks much

[trueno]

yes? no? maybe? please :-)

Jeff (narflex) will have to answer this one. Sorry for the delay.

I would really like that feature also. I only record one or two things a day so the bulk of the time the machine could be in standby saving power.

Thanks, at least I see you saw my post :-)

I already bought SageTV, so I suppose this is indeed a feature request, as I tried it and it doesnt wake up

thanks again

It doesn't do this currently, we'll probably add this in the future....but not timeframe yet.

Narflex,

Is the future here yet? I need to use PS mode because my HTPC is in an enclosed entertainment system.

Thanks,

Frank

No, not yet. Is the only problem that SageTV needs to wake up the PC on time? i.e. if you put your PC into hibernation with SageTV running, and then manually wake it up, is SageTV OK?

There's a potential workaround if this is the situation...

[jman]

i'm VERY interested in the workaround!!!

[Narflex]

There's a property you can set that'll export the reocrding schedule to a text file. What someone could do is write a program that does this:

1. Scan the recording schedule file to find the time of the next recording
2. Set the wakeup event in windows to awake a few minutes before that time
3. Puts the computer into standby mode

In theory, the computer should then wakeup before Sage is scheduled to record and Sage will start recording away merrily.

If "someone" could do this, could your in house master programmers do this for us? This seems like such an easy thing to do and all other pvr software like snapstream and showshifter can already do this. Please help us!

[falchulk]

Ok, since there was no response, how do you export the next recording to a text file when sage tv is put to sleep and only then? The only way this would work is if "someone" writes and app that scans a directory for a file and when it finds it, schedules sage to wake up. This should not be to hard, but I have a hunch that the text file would contain all recordings, not just the next available. This would complicate matters slightly but I think this is something I need to work on. Also, is there a command line switch that wakes sage up like sagetv.exe /wakeup? Or a way make it sleep automatically after a scheduled recording so that the next recording would write to the text file?

[jman]

i intend to give writting this a shot this weekend...(i'm a java developer)

two questions:
1) i see the entry in the property file...is there any info on the format, e.g. schema? (i haven't dumped it yet, so maybe it'll be obvious...)

2) is this file only dumped at startup?

3) so sage won't freak out if the system goes it to suspend? or do you recommend stopping sage when you suspend, and restart when coming out ( i sure hope generating that file doesn't take too long! )

BTW,

i calculated leaving my computer on 24x7 w/o suspend to be about $22 per month...(a bit more than $10/mo for tivo subscription price, eh? )

see site:

where computer 250W
satellite 25W,
$0.11/kWh

one of the reasons i bought sage in the is 'cause i'm cheap, so i may ditch it for something else if i can't get this to work...

[Narflex]

jman,

1) Its tab delimited, beyond that its obvious once you see it.

2) its dumped every time there's a change made to the schedule

3) This I don't know yet. I'm looking for some feedback on it. Test this first before you bother writing anything.

The first night I tried sage, I left it open and put it in standby. It appeared to still be functional when I returned the next day and brought it back to life. Granted, thats was a quick glance test before I came here and found out sage has no power mangement support. I am not a java programmer but do have consideralbe experiance with VB 6 and vb.net.
My idea was to create a scheduled task to call sagetv.exe /(wakeup switch) and thus bring the PC out of standdby (technically, I guess I could call a dummy batch file that does nothing at all). Does it have such a command line switch? I apologize for not knowing where the property was to activate the text file output. I am new to sage and currently at work so I could not check.

[mlbdude]

Why would you want to bring Sage out of Standby when you are not there? Or are you suggesting to just somehow bringing the PC out of stanby based on the SageTV schedule export file?

[falchulk]

The second one 'dude

[jman]

i can handle the parsing of the dump file, but does anybody know how to wake up XP?

I tried 'at' and 'schtasks', but did not awake from standby..

[falchulk]

jman, the only way I know how to do this is to create a windows scheduled task to do someothing. It can be anything at all like run a dummy batch file that does not do anything. Unfortunately, I dont know how to create the task in java.

[falchulk]

I know this is not Java jman but it might translate somehow:

Or if you want to just call a command line that will schedule the task:

at \\(computername 19:55 /interactive "(whatever command you want to give it)"

The latter is likely the easiest.
