I have a "problem" with power consumption. My vbox needs 8 W all over the time. No clients on, no EPG download ... -> No PID in use, but the tuner sill locked.

I've tried with also with ntp and EPG: OTA and xmltv.

Is this normal ? Is seems little big high !

Bye nepo!

P.S. Don't misunderstand, I can use the box, Look / switch TV, record and so one

Hi @nepo
8W is still within the norm
As the VBox consumes very little power, we keep both tuners always locked to the last used frequency
This way when a client is requesting a channel, it's instantly streamed

hi
Thanks for reply !

I have tested the vbox for a few days. Streaming and recording absolutely no problems !!! So I want to continue to use vbox.

8W is still within the norm
As the VBox consumes very little power, we keep both tuners always locked to the last used frequency

I don't believe that is "very little power" . I have tested different (little) computers (SBC: Raspberry3; orangepi+2E...) with also 2 DVB-C USB tuners, 2,5 device ... and they consume less power.

Anyway, the support makes a practical suggestion:

You can shutdown the VBox software by using this URL http:// IP>/cgi-bin/ManageApp/ManageApp?OPTION=48&shutdown_action=Shutdown+System+
And you can use a smart power plug to turn the power off and on - this way the VBox will not consumer any power at all

Here are some example of smart power outlets - https://www.postscapes.com/smart-outlets/

But I want to shutdown the vbox e.g. specific time automatically combined with timer switch outlet.
It is possible ? I have tried with editing crontab:

Code: Select all

*/15 * * * *	root	/sbin/shutdown -h now

or

Code: Select all

*/15 * * * *	root	/cgi-bin/ManageApp/ManageApp?OPTION=48&shutdown_action=Shutdown+System+

with no success

Please help

Hi,

This doesn't answer your question directly but I do the same thing from within the home automation software Domoticz that runs on a Raspberry Pi.You can set up a scene to turn off the VBox then after a delay of 60 seconds, power off the timer switch.

You do need to be able to send commands to the power sockets for this - I have an RFX433 Transceiver connected to the Pi.

Hope that helps.

[admin@vbox]

We have a customer that has a smart power that is also capable or sending a timed URL which he is using to shutdown the VBox
Also you can use any online/PC/Mac to schedule the VBox shutdown prior to turning the power off

hi
Thank you for your help

But I don't want to buy/run a third machine to shutdown the vbox.
The vbox is a linux machine, it should be possible to shutdown with an internal script/command ?

If you are using router that is openwrt or entware repo capable, you can use it's crontab and wget to get this feature.

hi
@ Ant: Thank you for your help!

I have thought about to use my Router (Fritzbox 7362 SL 6.83) for this job, but

If you are using router that is openwrt

It's not my router, only rented. -> high-risk to damaged the router. I don't want to do this.

entware repo capable

no telnet/ssh for version 6.83
No chance to use my router without risk/unreasonable expense

Again
- We have the possibility to shutdown the vbox (more or less)
- We can edit cron jobs (indirect: backups or direct: e.g. choose ntp)
- OS linux with a lot of possibilities to run bash commands/scripts

Dear Support/Admins: Where is the problem ?

Bye
