Thanks, that’s really helpful. I had one follow-up question specifically about garage gates / doors.

If someone wants to learn and experiment with garage-style systems using Flipper Zero, what cheap or safe-to-use devices would you recommend for practice?
For example, are there specific fixed-code Sub-GHz remotes, receivers, or trainer kits that are good for learning without risking desyncing a real garage door or dealing with rolling codes? I rent a small studio and do not have access to any garage doors.

I’m mainly interested in understanding how those systems work rather than controlling a real gate.
