Turn on kitchen hood when naighbour is cooking (lemm.ee)

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

Thank your for detailed comment.

Land lord is myself so cant do much about that part. Its a quite new building and lot of people share the same problem including the neighbour Im connected to. We also have active warranty and its against the law, but Im quite sure there is nothing we can do unfortunatelly. No free air flow after adding filter and flap, but yeah it looked like possible disaster.

I might dissasemble extractor to see possible way of mounting shelly 1 or simmilar switch in series with lowest settings position. Thats sounds prommissing tbh, but Ill first look what sensor is suitable. I am able to install sensor below where tubes meet, so all neighbours air will pass there. Just dont know what would be the most reliable.

Timer routine is not perfect since its far from silent even on the lowest speed
