@chrispi68 GitHub bot closes issues after a certain amount of inactivity to keep our issues clean. That's why it was closed. We're planning to do this. That's why I've reopened and added the backlog tag. backlog issues are things we definitely want to address habe event found the time yet.

And yes, like @Maschga says. What you're describing should definitely work today. Please open a discussion with more details.

@naltatis I've started exploring this. If nobody else is working on this, you can assign it to me.

Question on the "disable config ui" -> I intend to do this by disabling the "editing" buttons client side. Basically the client will know that it is running in demo mode. This way, you can still see the configuration page. Is that what you intended? Do you think it is important to also disable the api on the server side?

For "disable restart", I think both server and client side should disable that functionality to avoid accidents, does that make sense?

If you want to have a peek at size of the code changes, review here: https://github.com/guido4096/evcc/tree/explicit-demo-mode

Hi @guido4096, thanks for working on this. I've looked through your PoC commit and it looks good so far. I have some remarks like how to publish if we are in demo or not, but I'll post that once you've opened a PR here.

This way, you can still see the configuration page. Is that what you intended?

We should definitely disable the features server-side. For use-cases like the demo.evcc.io we dont want people modify the configuration. I'd remove the config ui page in demo mode completely. At least in the first iteration. I see that having a read-only mode would be nice for new users to explore all the toggles and switches, but this is not trivial and would require quite a bite of change.

Generally I'd say everything that is auth-protected right now should be disabled in demo mode. We could introduce a dedicated status code or message similar to 401 unauthorized (triggers login modal) that triggers a "not available in demo mode" message.
