VenusGX mobile display

Is there a more elegant way to display the VenusGX info direct to a mobile phone?

I have a job with a Venus GX, Multi, CANbus MTTP and BYD the customer has no wifi or internet and no computer besides his mobile phone, At the moment he is connecting direct to the VenusGX with his phone.

It is quite difficult to use and see the VenusGX interface on the mobile. The rendering is terrible and it only works in landscape. You can request desktop site in the browser which is a bit better. but still not good, see blotchiness around data readouts and bottom cut off in screenshot.

I would try to isolate the problem. In order of easiest to most difficult, It could possibly be with:

The customers phone/tablet - Try connecting with a different device and see if the problem persists
The firmware on the VGX - Update to the latest firmware
The Customers local network - try connecting directly to the VGX with an ethernet cable and see if the problem persists.
The hardware of the VGX - This is most unlikely, and the last considered option.

Yes, no need to try another Venus GX, this is not in anyway hardware related.

Look on GitHub there is an example of a nicer control panel which I believe is done using the mqtt back-end.

Alternatively, I have made a pretty nice dashboard by subscribing to the mqtt messages using node-red, processing, and sending them to grafana via node-red's influxdb plugin. While the data is in node-red you can do some really cool things. For example, I set z-wave thermostats to a low preset when the grid fails (load shedding).

Both node-red and grafana have nice dashboards that you can use with a touch-screen. As a bonus there are far more data points and many have more precision then they do on the standard UI.
