My Mods on Venus OS (Main Screen, Truma, Shelly, Weather...)

I use a RaspberryPi 3B+ with a 7 inch Touchscreen in my RV / Motorhome.

I think everyone knows the fantastic work of Kevin Windrem with his GUI Mods and like them as I do...

But I needed more. I wanted compressed information on one screen with less colors. I also need control of my heating (Truma) and lights (Shelly) and so I started my own modifications to the GUI (based on the GUI mods).

And this is the result:

I've created an app for my smartphone to control everything from everywhere as well:

... a BIG Data display that I clip behind the window so I can see the data when I'm sitting outside under the marquee/sunblind:

I've created a short video with the actual modifications of the GUI (part one).

Hope you enjoy it...

Hello,

Good !!
I've also start last week some tests and drafts.... I'm still far from your version....

RV side panel

From truck side ruck

I've spent some time with the station_pump icon not available with embedded awesome font ....
I will perhaps check on victron node-red wed site to find something...

The Mobile app is a good point !!!

Thank you for your comments here and on the other platforms so far. I'll make tutorials/workshops, so that every user will be able to do this byself.

By the way... I'm working on a new project, but this will take some time, because there are some technical challenges...

wow this is FANtastic. I’ll see myself out…

Jokes aside this is really cool. I don’t have a Truma but I DO have a maxxfan. I’d love to build this into my van. Any chance you want to build an integration for a houghton air conditioner???

Looks great. How do you communicate between Cerbo and Maxxfan?

I have both in my van.

two different types: sending IR-Signals via WiFi or USB-Serial.

I'll explain it in detail soon. Did you mean CP Plus instead of iNet plus? The communication is between Cerbo, a LIN-TI-CI controller, MQTT and the CP-Plus

Hello,

On your DC System, do you have a smartshunt or is the power value deducted by the Cerbo ?
I'm usint a BMV 712 to evaluate my DC load .. and i recently connected an MPPT on this DC circuit... the value reported now is completly wrong ... even if the BMV712 report the correct one.

In my productive system I have a BMV 712 as well. In my development system I use a smartshunt.

What do you mean with "completly wrong"? What is shown?

0 ·

honu itsme commented · Mar 09 at 01:08 PM

Allright ... i'm dumb... i checked all settings and cabling.. wll was right ..; then today i just seen that the BMV712 was not in the device list of the CErbo anymore => There was a wire cut on the ve.direct cable between BMV712 => Cerbo,n this is now fixed and the value reported by the Cerbo is now the good one ... !!!

Sometime i feel so dumb to have omited an obvious thing to test.µ
Sorry for all the hassle guys.

jaymusician commented · Mar 08 at 05:22 PM

If your MPPT controller is a Victron model and it's connected to the GX device (usually via VE.direct cable), then the solar output is automatically deducted from the DC wattage. Otherwise you would need to connect another shunt between your battery and MPPT controller to isolate its output, along with some extra config in the software.

honu jaymusician commented · Mar 09 at 11:24 AM

It is a victron and it is connected to a ve.direct cerbo conenctor and correctly reported in the cerbo display.

The main important thing for me:

How did you integrate the truma in VictronOS ?

Do you use node-red dashboard and if yes, how can I integrate the gui-mod start- page as page 1 of my new dashboard?

0 ·

itsme ak68 commented · May 14 at 08:12 AM

It's a combination of code, driver, node-red, graphics,... The mainpage (Victron default or with GUIMods) is still active.

karelholubicka answered · May 18 at 07:46 PM

Well, huge respect to you.

Due to many different things incorporated in our car (Cerbo, bms, switches, lights, Truma) I started to create an app in Visual studio 2022 MAUI in order to be able to control the car via Android, iOS and PC. It had painful slow performance, so I postponed the development until MAUI more matures. Now I will trash it fully, as when I will follow your way, I can handle everything from the Cerbo and remote console, without another display HW. I was thinking about this way before, as Cerbo is just a comp with OS anyway, but was not sure that I can deal with it. You proved it is possible.

If you want to monetize your hard work a little bit, just let me know. We'll see. Regards, Karel

Thanks to inetbox2mqtt (https://github.com/mc0110/inetbox2mqtt) and NodeRed, a technically functional connection between VenusOS, CPplus, Truma AC and Truma Combi6E has been running quite reliably for a while now.

Relay 1 set to "ON" via VRM activates the Truma ACC (automatic climate control) in the CPplus and sets the temperature to 21C. Heating and air conditioning decide among themselves whether to cool or heat. Switching off takes place when the relay is deactivated. Works, even from remote but is not yet the final solution. A visually appealing control as in your screenshots is still missing.

Have you (@ItsMe) made any progress in adapting the QML on the GUI v1 or releasing them?

Hi Marcus,

just wondering, how far you are with the manual for the Truma integration. I'm really exited to reproduce it. In regards to hardware, I have an existing one from WomoLIN in mind, but I'm not sure, which one to choose, the TI-CI-LIN Controller or Interface?

Cheers,luphi

PS: A simple unformatted text document would be absolutely sufficient. I don't require a nice and shiny video. ;-)
