Wireless remote screen using Raspberry Pi - Possible?

I've searched here and Googled elsewhere and haven't found what I'm looking for so maybe one of the smarter than me people here can tell me if this is possible. I have a 40' RV with my Cerbo GX installed way in the back. I want to have a display for it up front roughly 35' away. Is there a GOOD way to do this? A tablet running the remote console is not good. I was thinking a Raspbery Pi running Venus connected to the network via Wifi or Ethernet somehow slaved to the Cerbo or has someone come up with a way to install the GX Touch 50 remotely?

Hi have you tried running the MFD App on the tablet (which can if you like it also be ran on a rpi no doubt).

See MFD App section in the Cerbo manual.
https://www.victronenergy.com/media/pg/Cerbo_GX/en/marine-mfd-integration-by-app.html

Extending a HDMI signal over that distance (for the GX Touch itself) might be possible; or not; but I wouldnt know.

“Slaving” a second gx device is not possible I’m afraid.

So far, the MFD is the best option I've found other than using the CSS edited Remote Console to remove the arrow keys. The biggest problem with the MFD is I haven't found a way for it to display tank levels. Am I missing something?

right, that is missing the tanks. Which were left out on purpose, since the original idea (showing this on a marine MDF) doesn't need tanks: the MFD itself can show tanks.

however, thanks for the reminder - for many use cases it would be nice to have the tanks; I'll make sure its done.

That would be great! An option in Venus to remove the directional keys from the remote console would also be a fantastic addition with minimal reprogramming. It would allow an easy option for running the remote in a kiosk browser for any tablet or RPI without having to edit the CSS which I hear is easy to break with new firmware updates.

Hi

You can run a raspi in Kiosk mode in wireless mode and control and view data from that screen quit easily.
As i have done this on a couple of sites.

Connect a TP-Link TL-WA901ND with Ethernet to the Cerbo.

Configure the TP-Link as an access point

Connect to the AP and start the Remote Console or VictronConnect

What will that do other than add complexity? Sounds like that would help with range but I don’t see how it’ll give me a more functional remote.
