Turn on kitchen hood when naighbour is cooking

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

My first thought would be an air quality sensor but I'm not sure how sensitive they would be to food smells. I've never used one but there are plenty of examples online.

A fallback would be a timer, if you know when your neighbor usually cooks, you could turn your fan on during those times with some buffer.
- They are plenty sensitive enough usually. Mine Ikea one definitely knows when we are cooking, even when the hood is on.
  
  Which one do you have? Sounds promissing

  But the new one that is ZigBee OOTB is probably better
  
  Thank you, Ill check it out
  
  Can confirm these are very sensitive. Mine is the other side of the house and picks up when we're cooking
