HI all
Has anyone managed to write a script that will run all the modifications and changes back to the RPI after a version update? like headless, touchscreen, screen dimming and timer. So we don't have to redo this every time.
I've read https://www.victronenergy.com/live/ccgx:root_access but cnat quite get my head around what is needed? I'm no programmer but I dont mind a little tinkering if I have some guidance.
Thanks
Mark
There is some useful information here with some examples of what people (myself included) have done: https://community.victronenergy.com/questions/13646/upgrading-pi-erased-settings.html
That’s awesome thank you, I’m guessing that you put the updated files in the /data folder along with the script if I’ve read it correctly lol. As I also add a folder for adc and relays and gpio list.
Thanks
Mark
Yes. I keep the modified files and script in the /data directory where they are preserved.
Thanks i'll have tinker tonight and hopefully get it work working.
On a different note..... Do you know how to change the resistor values for the tank levels? id like to monitor my LPG but the sender is only 0-95 ohm. I have the water tank one working no problem but that sender is the 0 -190 ohm.
I cant seem to find where the settings for the values are? Ive found the relevant pages in the gui folder tanksettings, sensor settings and settingsJS but i'm not sure where the resistance settings are?
Cheers

I was thinking of putting all the (re)configuration files onto a removable USB memory stick then it can be plugged in any time you need to fix a configuration. This would be particularly useful if you keep more than one Venus os SD around so that you have a spare in case of corruption ( which has happened to me in other Rpi projects)

Thats an awesome idea if you manage to get that working i'd love a heads up how you did it.
I'm still trying to no avail :( to find out how / where you alter the tank resistance settings.
Thanks

I have created scripts to add support for the "Official Raspberry PI 7" Touchscreen" and the CANable CANbus USB interface.
https://github.com/kwindrem/RpiDisplaySetup
https://github.com/kwindrem/VeCanSetup
Both scripts add code to reinstall components following a Venus OS upgrade. /data/rc.local runs every time the system boots, so the code there checks "flag" files that are wiped out by a Venus update to control whether to run the setup scripts. If the flag is missing, the related setup script is run again.
Read carefully the introduction for the display setup as unannounced reboots can occur to run touchscreen calibration.
Hope this helps or gives you ideas for your own scripts.
I have rewritten my RPI mods they are now here
