Hey peeps, I moved to a new appartment and my kitchen hood is connected to the same pipe (chimney) as hood from appartment below. The issue is smell coming from our hood when neighbour is cooking.

I was thinking about some kind of sensor (air flow or humidity or smell?) that can detect when neighbour is cooking and then HA would turn on our hood at the lowest speed.

I have no clue what kind of sensor would be suitable. I also need to figure out how to start our hood with HA (hacking with relay or buying some kind of smart kitchen hood is acceptable). Our kitchen hood is just regular Faber with 4 position switch for selecting fan speed.

Anyone have idea how to solve that issue? What sensor would be best for that?

Note that I have already installed 1-way valve (not sure whats the correct english word) and 3 different filters, but still sucks

Edit: I got some things going on, cant replay to all comments today and probbly tomorrow. Thank you all for input, Ill come back asap

    Shove a thermocouple up the duct. When neighbor is cooking it will likely affect the temperature in the duct noticably. Use that as your fan trigger.

      I should test if air temperature is high enough after 5-6 m of vertical travel. If you know any device that can do that please link. Unless you are talking about full DIY?
