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

Could you add a fan at the exhaust end to create an ever present, gentle, negative pressure to encourage the air to flow that way?

Acinfiniti makes duct fans that have a temperature sensor and when it detects the change in temperature it turns the fan on. I took one apart and used the sensor, pcb and fan in a different project without problems.

I could install this kind of fan

I was thinking about this, but feels confusing how to sync it with extractor fan. Not sure if it should be on or off while our hood is running, and would it reduce air flow too much. I dont think temp sensor is optimal for this, but I might be wrong. Some guys mentioned air mass and air quaility sensors which feels better I think
