Problematic Hobbiest?

I am only a few months into implementing HA, but I am not convinced this works standalone for periods of time. Is this more of a hobby sort of thing or an implementation for running on it’s own.

I find that I cant let this run on even a pi with more than basic integrations and feel comfortable they won’t stop. But I am also a hobbiest so I check on it regularly and reboot and then its all good again.

I’m not complaining. I’d just like a frank answer.

Can I realistically perhaps go on vacation for a week and expect it to run itself without me having to check for failed integrations, lost connections or devices getting left out.
