what a waste of technology. you could have had a pen and graph paper hooked up to an microphone 100 years ago and looked for the spikes in the time set.

Yeah idk why home assistant needed to get involved. I guess to turn the system on and off according to his heuristic.?

it could also be common sense.. you live in a noisy city and you are wondering what the noise is.... maybe it could be the city itself? how about sleep in a different smaller town and then ask yourself the same question, you'll probably get a different answer.

I'm not sure if things are really that simple, at least from my personal experience. I think the quality of noise and noise floor can make a difference
