Rpi4, no relays and IOs?

I'm sorry if this is already documented, but I just realized that I don't have the relays and IO menus in the Venus anymore. My rpi3 burned recently and I had to replace with a v4.
I can't find anything about it. Is there something needed to have them available?

There is probably no /etc/venus/gpio_list file (or it's empty).

I have a setup script that deals with this:

You need SetupHelper for this script to work:

I assume you have an I/O board of some kind. That may also need to be configured.

Thanks for your help Kevin. I'm starting to think that it is intentional. If one tries to install the stock gpio node in node-red, it automatically gets deactivated.
That seems to be caused by missing components on the SO for driving the ports as it is registered in the log.

The release notes for v2.80 beta covers remounting the root file system read-write. There's a link to the description of why this was done also. I doubt seriously if there is any intent to prevent enhancements. More likely it was an oversize or side effect of changes. That's what beta releases are for: to uncover problems before it's released to the general public. I'd make a detailed report in the thread about this beta release (it's a sticky).

Yes, that was too much on my part. RO filesystems are also good on sd cards.
BTW, I've been looking at you project and it's awesome. I would like to contact you for some questions, like how to turn active low all the relays, or adding things like aliases or custom drivers for other meters.
How I can write on on those? A github issue?
