Hi,

 

I need a simple script to send a Diseqc command - e.g. change port to B. Could someone help ?

 

[mrvica]

I just compiled it without testing, you´ll propably have to stop enigma2

usage: FRONTEND=/dev/dvb/adapterX/frontendX diseqc [test_seq_no]

root@h7:/tmp# ./diseqc
diseqc test: using '/dev/dvb/adapter0/frontend0'
open: Device or resource busy
root@h7:/tmp# init 4
root@h7:/tmp# ./diseqc
diseqc test: using '/dev/dvb/adapter0/frontend0'

The program seams to work but nothing happens. 

 

I have 4x1 1.2 diseqc controller.

Hi,
Thank you very much for your prompt answer.
I don't know much about coding.
Could you instruct me how to use the script you wrote.
Thanks again.

 

you wrote a P.M. to me but I could not answer it, could be a board problem, so I am putting it here, there are much more people to answer it

Hi,

 

I did more testing and.... it works!

 

Marvica - thank you very much for your help!!!

[mrvica]

people surely want to know how you did it, how did you get the tuner to not be in use (maybe switching to an IPTV service?), you wrote down the sequence you got starting diseqc without parameter and then use that parameter i.E.

diseqc e0 10 38 f7 00 00

Am I right?

[john448]

I have VU+ Duo 4k SE (with FBC tuners) which doesn't turn off LNB power in standby mode. By changing diseqc port to B (to which nothing will be connected) I will eliminate power consumption.

 

Here is a script which checks if a tuner is in use. If no tuner is in use the Diseqc switch will be turned to port B.

 

 

diseqc.sh:

 

#! /bin/bash

 

tuner=$(ps | grep -c kdvb)

 

if [ $tuner -le 1 ]

then 

source /usr/script/diseqc 3

 

fi

 

 

 

In LNB settings I added Diseqc 1.0 command - port A

 

 

And finally I put this line: 

 

*/1 * * * * /usr/script/diseqc.sh

 

 

in  /var/spool/cron/root file to run the script every minute.

 

 

Ps. VU+ consumes ~18W in standby mode and 14.5W without LNB connected.

interesting! an undocumented feature of diseqc

You can try to add this solution to the image as an option in the tuner settings.

Perhaps similar lower consumption could be achieved with the following empty channel in userbouquet.favourites.tv or does the tuner stay on?

 

#SERVICE 1:0:1:0:0:0:0:0:0:0:EMPTY:EMPTY
#DESCRIPTION EMPTY

 

If john448 could take the time and measure the consumption, it would be interesting.

I have VU+ Duo 4k SE (with FBC tuners) which doesn't turn off LNB power in standby mode. By changing diseqc port to B (to which nothing will be connected) I will eliminate power consumption.

 

I wonder what the point of this is, as a VU+ always powers all inputs, not only the selected tuner. Even in standby.

 

This is done by VU+ to work around a bug in their drivers that they don't seem to be able to fix (if A is in use, a recording starts on C, then A stops, and the LNB power cuts with only a leaf tuner in use).

 

The only way to reduce power consumption is switch the box off.

[Abu Baniaz]

This was mentioned to the OP on another forum. It was suggested that he uses a power timer to put box into deep standby

 

standby = switch off display and audio. everything still running

deep standby = everything off apart from waiting for remote response or recording timer.

[WanWizard]

There are boxes that cut the LNB power in standby as well, but the VU+ doesn't. Its hardcoded in the current drivers.

This solution does reduce power consumption by about 2.5W. It cuts off the power to LNB. Of course deep standby is the best solution but the network is off.

Tuning to empty channel has no effect on power consumption.

[hw9258]

Thanks for measuring the empty channel consumption and reporting it back.
