Maybe this add-on isn't working or you just don't know what to do. You can resolve almost any issue by following these steps:

Check the FAQ
First check out the add-on FAQ. Reading documentation is boring, it's true, but the developer spent a lot of time trying to make them easy to read and follow. If you're lucky, your question is already answered there.
Check the Forum
Next, try checking the add-on announcement forum post. Your question might already be there, and if not it's a good place to ask. If the developer can't answer your question, it might be that another user can help.
Check the Logs
This add-on makes its debug logs available. They're pretty cryptic but might give you some context for what's going wrong. Sometimes, an error only shows up in the Home Assistant supervisor logs, which you can get to from within Home Assistant by clicking "Supervisor" > "System" > "System Logs" > "Refresh".
Restart Everything
Restart the add-on. Restart Home Assistant. Reinstall the add-on. Technology loves to be restarted, it's amazing how many problems it can solve.
File an Issue
If you don't want to ask something in front of the angry mobs on the internet, you can file an issue on the project GitHub Issue Tracker, just click "new issue". The developer gets an email if make one of those, which he promises to try and help with. No question is stupid.
Reach out Directly
I put my name on this and I want it to work well for you. You can email me at stephen@beechens.com

Maybe what you're dealing with is of a more, general nature? Home Assistant has a lot of rough edges, but really anything can be frustrating.

Take care of yourself
Make sure you've had enough water to drink today. If you love coffee, it might be time to put on a new pot. If its late at night, now might be the time to hit the sack. Everything is more difficult when you're not at your best.
Get a fresh perspective
Take a walk, seriously. Sometimes the mind gets so fixated on a problem that it can't think around it anymore. Explain your problem to a duck and you might see the solution was obvious.
Be realistic
In a week you're unlikely to even remember this moment. Next year, you're going to be a different person, with a different mind. If you have the spare time to get frustrated at how your home automation system stores its backups, then whatever you've got going on in this moment is probably small potatoes. You've always been the one to decide how you react.
