In Topic: Shell-script - Diseqc command

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.

 

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. 

 

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.

 
Tuning to empty channel has no effect on power consumption.

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.

Hi,

 

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

 

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

The program seams to work but nothing happens. 

 

I have 4x1 1.2 diseqc controller.

I have VU

 

Why? Also the voltage is part of Jess/unicable you cannot change it permanent to 18 Volt…? And why should it be active when streaming?

I have VU+ Duo 4k SE with FBC tuner which doesn't turn off LNB power in standby mode. By changing voltage from 13v (receiver in standby mode) to 18v (receiver ON or LAN streaming) I can design the switch to kill off power to LNBs while not in use.

I plan to use 4 LNBs - which means about 10W continuous power consumption.

 

PS. Thanks for quick replay.
