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

Habe you thought about a mechanical solution, e.g. back pressure flap?

Yeah, I have filter box and back preassure flap, but there might be something better that Im not aware off.

From let to right: filter box, flap, flexible tube

I also fitted carbon and heppa filter in the box

Then I would consider this flap defective, because you are actually experiencing the bad smell.

When your own device isn't on, the flap should close and it should be (nearly) airtight.

It is nearly airtight IMO and its night and day difference with/without flap. It is easy to inspect how it moves when I remove filters from filter box. Im not excluding anything here tbh

It is insane and hard to believe, but its easy to guess what meal my neighbour is preparing while it looks like there is no flow at all. After long cooking it becomes annoying especially with onnion or fish...

The other appartment installed 2 flaps with no difference... In our building I think all 3rd floor kitchens are connected to 1st floor, also 2nd to 4th floor are connected. 10 appartments on each floor means up to 40 appartments with the same issue. They have installed flaps to anyone who complained and no one is happy with results afaik.

I replaced mine with (probably) better build quality one, but there might exist even better flaps. Do you know any source in Europe for the best quality flaps. We wouldnt mind spending much more money if that can help
