EDIT: In hindsight, I think I should've looked into posting this in a different community.. It's closer to a silly "innovation".. soo.. is this considered FUD? I also don't support smoking or vaping, especially among kids. Original title had "privacy-violating" before the "solution".
Ok but this is very simple. Everyone can set up something like this using home assistant and a few sensors connected up to it
Everyone can write software? I'm fucked then... Guess I'll be homeless now
set up != write software
From the little I played with Arduino's IoT platform, I honestly believe that if there is a compatible sensor that can detect vape smoke, almost anyone could get a simple version up and running. It was a very simple and largely automated setup if all you want is to get the sensor output to the portal and then link it to a UI element.
Of course gluing together this software is more complex than that, but it's no grand feat either.
No one said it was a grand feat. I said it was quite a bit more than hello world which it obviously is. Even if it's only setup which we've no reason to think unless you think most people who claim to have written apps are lying
