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

Sounds hard If you can’t hook into the neighbours stove or hood. Maybe detect if the hood of the neighbors is turned on through a windspeed sensor (these things that rotate). TBH this sound like you should just fix the mechanism/back flow valve that restricts the airflow coming in if your hood is turned off.

Not the best option, but still doable. Hooking into neighbours hood could be possible if I implement the same thing on both hoods since they want to solve the problem more than us. Its like 7m distance and I could guide the cable trough the tube.

TBH Id live to learn how to fix back flow valve or buy better one if it exists. The thing is, all valves simmilar to mine are not made to stop smell afaik. And hood is not strong enough for water tight valves, at least others told me that
