HowTo: Disable Hotkeys in Venus Remote Console on LAN

As requested in the community, it should be possible to disable the "hotkeys field" in Remote Console on LAN. To be able to make the GUI going fullscreen, on a tablet or some kiosk mode display for example.

To do this, I created a modified Stylesheet: styles.css styles.css.zip

Copy it on your Venus device to /var/www/javascript-vnc-client/styling/styles.css

To copy the file, you have to enable root access, following these instructions:

https://www.victronenergy.com/live/ccgx:root_access

After clearing your browsers cache and reloading the Remote Console on LAN page, it should look like this:

This is someway update proof, as long as you don't clear you browsers cache again or change the IP address of your Venus device, the modified styles.css will stay in browsers cache after updating Venus to a new version.

The hotkeys field on Remote Console via VRM is not affected by this mod, as the hotkey controls are created by the VRM webpage.

I use this modification, to have a local fullscreen display for a VenusGX using a Raspberry Pi with display attached and Chromium browser in kiosk mode. It is also possible to connect with a VNC client to the Raspberry Pi with multiple sessions at the same time, so you can have several mirror displays, showing the same, and you are able to control Venus from every mirror.

If you want to know, how to get Chromium in kiosk mode on a Raspberry Pi, read: https://community.victronenergy.com/answers/4280/view.html

If you have some further questions, I will be glad to answer them here, if I can ;o)

Regards,

Markus

Hi,

Tried the stylesheet. The only problem I have is the keys are removed but the white space is still left in place of keys. I have to zoom 150 % to fill up the screen.

Any setting I can apply to zoom the tiles on load.

Hi, @Anil Ghatikar,

really?

It seems something has changed recently.

The new path for the stylesheet is: /var/www/venus/styling

I tried to put the modified Stylesheet there (2.30-32) and it works.

I tried on IE (Windows) and Firefox (Mac) both work without a white frame.

But yes, you have to set zoom level to match full screen resolution.

The Raspi Kiosk mode (set up following your posted instructions) saves the last zoom level in my case and it is therefore going fullscreen after every reboot.

I am so thankful that you brought me to this idea, I absolutely want you to have this working too, so I will help you to get this done!

Regards,

Markus

PS: look at attached screenshots. (without zooming to fullscreen) do they look the same in your case?

Its obvious to say that your screen size has to be the same ratio than 480x272 to get 100% full screen. My "Master Mirror" Raspberry Pi has exactly set this resolution. Every additional VNC mirror can fit scaling to match the ratio on any resolution.

Thanks! Could you explain how you've setup your VNC mirror or link to a guide? Can't seem to find anything thats working.

Hi.

This is a super easy task:

Activate VNC protocol in Raspberry Pi settings.

After that, download a VNC viewer on the device that you want to have the mirror and connect to the IP address of your Raspberry Pi.

If you register to the VNC cloud you are able to connect to your RasPi from everywhere not just inside your LAN.

Pls. try that out, and if you have further questions I will be glad to help.

Regards,

Markus

This is great but have two questions:

1) How do you back out these changes. I tried removing styles.css but that caused the page to fill with icons.

2) Is it possible to change the resolution for remote display on a CCGX where there is a local display?

Looks real nice, however mine looks like it’s zoomed in. Is that possible to fix somehow?

Is it also supposed to disconnect the console in VRM?

I have the same issue. Hopefully someone can help with this

try this and it works :

.remote-console-popup-container.logged-in {
width: 100%;
height: 100%;

/* This is needed to prevent the canvas becoming tiny on some occasions.. */
}

Thanks @Glen I had the same issue (a zoomed in corner) on my fully kiosk tablet after a changeover from a CCGX to Cerbo, editing how you suggested that bit of the stylesheet fixed it! :)

Al Al commented · Mar 17 at 04:22 PM

Just an update as I tested GUI V2 Beta today, and reverting back to GUI V1 caused the stylesheet to go back to standard, so I had to put it back again, and edit the Width/Height again as above.

The directory for the stylesheet has moved since Markus originally made this thread, it's now at:

/var/www/venus/styling/

Al Al commented · Mar 21 at 03:32 PM

Hi @Markus I'm finding the modified stylesheet is lost each new VenusOS update. I just updated to VenusOS v3.30 and had to upload again to the newer directory. Is there a workaround to keep it persistent? Should I also update the styless.css.package and styless.css.orig ?

Thanks

I think it would be better if it was switchable. Both panels, only tales, or keypad only.

Works perfect with tablet and kiosk mode. Thank you :-)
