It starts with a little insight and ends with data hoarding. I have independent temperature, humidity, and air quality sensors in every single room. I’m chasing that data dragon

That is 100% my goal.
Be your own, local Alexa ;)
The stove top extractors are especially important if you've got a gas cook top, those things are baaaaad for you :(
Add CO~2~ or pm 2.5, and you'll really see when you cook. Boiling pasta doesn't do much in my place, but my humidity ranges from 65-75%. (I prefer to watch the dewpoint, which is basically glued to 19°C all summer)
How nice to See someone with a clue about thermodynamics
I have a CO2 sensor I got from China for like 35 bucks, and was able to reverse engineer the api
I recommend a dehumidifier! Great to keep humidity down.
Why not wire the hood to an air sensor?
Most hoods are plugged into an outlet in the cabinet above it. Just pop a smart plug in there and leave the switch on the hood on.
I used a Shelly relay to add smarts to my dumb hood. Just interrupt the switches.
That powers the light too, so I'd rather not lose that.
I may try, but I'm in an apartment and I'm not sure if I can pull it off without damaging the hood.
I'm in the market for air sensors (temp, humidity and quality etc). What are some good options for HA?
I like my Apollo air 1. I have an alert set for when the air quality is poor for over 30 minutes, but mostly it just shows up after I made toast.
