The typical advice (from anyone who hasn’t outright drank the kool-aid) is to avoid automating things like locks or doors. If your shit gets hacked, (or if someone just shouts “hey Alexa, unlock the front door” through your window), you don’t want it to allow physical access. And automating door unlocks is an easy way to accidentally allow people into your house.
Instead, most try to focus on automation for things like lights turning off when you leave home, automatically dimming the lights when you start a movie, automatically stealing from billionaires when a new movie hits streaming services, blocking ads, self-hosting your own smart speakers to divest from Google/Amazon/et al., meal planning, hosting D&D sessions for players/DM to connect remotely or cast to a screen, etc…
Leave the locks dumb, because you can’t remotely hack a pin and tumbler deadbolt. Leave building molotov cocktails dumb, because it can be a fun bonding activity for the whole family.
And you should be using kerosene instead of gasoline. It burns slower and takes longer to evaporate when spilled, allowing more things to properly catch without creating risks of stoichiometric explosions from aerosolized/evaporated fumes. If you’re having trouble getting it to properly ignite, a little bit of anhydrous rubbing alcohol, (commonly found in any electronics store, typically used for cleaning computer parts), or just regular gasoline in the mix will help it take faster. And use a wick (in a molotov’s case, a rag in the bottle) to get it started, as the additional surface area allows it to catch much easier. If you’re making them ahead of time, seal them with a soft wax cap, so you can simply push a rag through the seal with your thumb (and briefly invert to soak the rag) when you’re ready to use it. The wax will simply add extra fuel once it is burning.
