OK, I'll keep an eye on it. No adverse effects yet - good work, thanks.

I'm doing some other testing and stuff atm so want to keep the server up -
I'll possibly take it down at the weekend, make some power measurements
and post them

Yes, the TV tuners always did run warm, and I recall that when VDR is
stopped the power is several watts lower (not because of VDR/CPU load
itself according to stats, it's when the tuners go active - hence my
interest in your patch).

As the server also runs the home automation/lights/heating/security,
CCTV, mail server, and file storage/Owncloud it's not an option to shut
it down when not recording, and I have t choose when to take it down !

I remember I've read somewhere (may be at vdr-portal.de) that you had
plans to re-work the dynamite plugin and implement the idle part
separately.

Well, it's a matter of style. "On" is a typical VDR name for such
arguments. "Down" looks good as well as "PowerSaveMode" or
"PowerDownMode". I'll consider this change. Thanks.

 I agree with you. I hope, dynamite was a little inspiration for you. :)

 I plan (for several years now, sadly) to break out the udev-part of dynamite 
to make the vdr more dynamic in device
management. The idle-part is a good first step in that direction.

 I think the name of the parameter is a bit misleading. With On == true you 
mean, that the device is powered down.
 Either rename the parameter to "Down" or the function to something like 
"PowerSaveMode".

While testing set VDR log level to 3 (--log=3) and use this helper
script to monitor your frontends:
http://pastebin.com/uW4NW0rZ

Don't forget to enable power saving in the Setup->LNB menu.

If you don't have sudo (you're not on Debian or Ubuntu), remove it and
run the script as root. It would be great if you could measure the
power consumption of you tuners (at least the USB one).

For about a month now. Tested with 3 different DVB-S/S2 tuners with
VDR 2.3.1 and VDR 2.2.0 (requires minor changes to the patch) - rock
solid.
I don't have VPS, so I can't test it. The same is about DVB-T/C

disabled (and it is disabled by default),

[vdr] [PATCH] Device power saving feature

2016-05-26 Thread glenvt18

Hi folks.

This patch introduces a feature which allows an idle device (a device
which is not currently recording or streaming) to enter a power-down
mode after some period of time. Given two timeout values,
PowerdownTimeoutM and PowerdownWakeupH, it works like this: when a
device becomes idle, it is kept powered up for PowerdownTimeoutM minutes
doing, for instance, an EPG scan before it is powered down. If the
device is still idle and has been powered down for PowerdownWakeupH
hours it is powered up for PowerdownTimeoutM minutes and so on. When
recording, streaming or a forced EPG scan starts, the device is powered
up and it's idle timer is disabled. This implies that PowerdownTimeoutM
should be enough for a full round of EPG scanning (20 seconds *
number_of_transponders). Another option is to run EPG scans from cron
(at night) and use SVDRP SCAN command.

Actual implementation of power saving facilities is left to a derived
device class. In the case of a DVB device it is implemented by closing
it's frontend device. For a DVB-S/S2 tuner this usually means powering
the LNB off. My measurements show 3-4W power consumption drops per tuner
for various DVB-S/S2 tuners. So, this feature (together with HDD
spin-down) is especially valuable while running a headless 24/7 VDR
server and/or using several tuners. A SATIP device can also implement
power saving if it is supported by a server.

I know about the dynamite plugin, but 1) it does much more then this, 2)
still requires a VDR patch, which is bigger, 3) doesn't work reliably
for me and 4) I think this functionality should be part of the VDR
core.
