Is it possible to rename Cerbo-GX relays?

If that’s not possible, this would be a very useful feature to add.

There are multiple questions on this. No it is not possible but it is on the roadmap for possibly the next version.

True, I saw it later, I should have seen it earlier. But good to know it’s about to be implemented.

But this isn’t just a DIY demand, right?

I have no idea, I am not Victron employee so do not have access to that data.
