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

I wouldn’t bother with that, I’d instead look at it from the other point of view and think about fitting something like a simple vent gravity flap to your hood outlet, that is closed when your hood is off, and opens when your hood is on. I.e seals the vent to prevent smells.

Yeah I did that, but didnt help. Got the best one I could find (with rubber seal), but smell is going trought... Is there anything better available?

And it’s fitted properly? Is it completely closed when your neighbour has their extractor on?

[–] rambos@lemm.ee 1 points 8 months ago (1 children)

Its closed unless my extractor is on! Its also intalled properly (axle in vertical pisition), but there are some tiny gaps around the hinge which obviously cant be sealed. Its fitted properly, with seals and silicon, and then I even duckt taped eveything just to be sure. It was not that bad with flap only, but then I installed filters (carbon + hepa + dust) and it improved even more. But still sucks hard sometimes

I would go around that hinge with a silicone cartridge, trying to close these tiny gaps - but use it sparingly, in order not to block the motion.

I would also look around it's outside, where it's mounted, if there are any possible gaps. There you can use the silicone generously.

I dont understand how can I do this without blocking the motion?

look around it's outside

Rubber seal (on filter side), silicone and duckt tape is what I used to exclude that. There is also no smell in the cabinet so Im quite sure its coming from the hood
