question

I did some more research and it is clear now, that the venus gui is QT based, which means we do not have a web engine on venus which would be capable of hosting the node-red dashboard. I was misleaded because of VRMs remote option. But this is just a VNC channel.

Ok, so next step, we need a web engine, any ideas ?

Ok,it seems to me that I am just talking to myself :(

I post the result of my further investigation here, it may be of some use for someone on someday :):

• Besides Venus QT main gui, there is also a local hosted HTML5 GUI, accessable by typing http://venus.local/app (mqtt broker must be enabled)
• So we have here two user interfaces which are only reachable from a sencond device in the same network, not from a connected (headfull or headless) touch display.
• Possible solutions imho:

1. Use a second RasPi in kiosk mode
2. Extend the QT GUI to include a browser tab, which loads a desired local URL on startup. (Position of tab and URL should be configurable )
3. Install an additional Webbrowser which loads on startup, replacing QT main gui.

I would prefer option 2, this seems to me the most reliable solution and we continue to load the qt gui on startup.

I also would like to display a custom page on the Venus gui, originally I was thinking of customising the Venus HTML5 app, but your node red dashboard looks like a good alternative. It would be great to have the ability to show a browser tab on the Venus gui. I’ve only just started researching this so can’t be of much help in a solution.

Well, not really another answer to my own question, but I found another interesting alternative to use a second display for nodered on venus os. There are these perfect serial displays from nextion. They are featured enough to show a local gui, which has to be designed with a free tool called "The Nextion Editor". A compiled GUI can than be transfered to the display just by inserting a sd card. After deployment one can send well documented serial commands from NodeRed to transfer values or react to events from the built in touch display.

This way Victron could embed another display option for nodered and has even the option to sell a second display ;)

There are two smart german guys who already went in this direction. They call their project PeKaWay and its (somehow) OpenSource. Well, the display GUI not.

Here is an example of my first designed GUI for the nextion. (Please don´t ask, there is not an nodered flow right know to drive this GUI ;)

I will keep this post updated ....

I want to say there is an option to install the Venus packages on Raspbian. That would give you a desktop you can boot into with HTML rendering like a magicmirror type thing.

I do like where this could go though.

does someone know how to write qt interfaces?

would be amazing if we could add another page as a kiosk webview, like in this example.

You can run venus headless (on a raspberryPi for instance), and you can install a web server or a x server for a gui on topp, if you want to.

Hi, I'm just landing on this topic, any update ?
