Write household lighting rules in ordinary English, then replay events to see how Jev applies them to simulated lights and blinds.
Only you can see your notes.

Code keeps the clock and motion timers while Jev chooses an accessory setting or leaves it alone. Changes below a selected-answer probability of 0.6 are skipped; that cutoff is not a validated safety rule, and the test command repeats live paid requests.
Before automating your home, ask a developer to build a virtual version of your rooms, lights and rules with this simulator. Describe events such as motion at night and write the results you expect. Its printed timelines can help you spot rules that conflict with each other.
Every event judged by Jev sends the rules, room details and current device settings to TypeSafe's paid AI service. The test command does this too, repeating the examples three times. Start with the virtual rooms, not real devices; a successful simulation does not prove safe behaviour in your home.
