Three years ago we permanently moved from Newton, MA to Sunny Isles Beach, FL.
In Newton we had a house but in Sunny Isles we bought a Condo.
One of the Condo disadvantage - a lot of heavy cigarette smokers around.
And the worst one - is a heavy smoking neighbor in the adjustment apartment.
We have a big Balcony with an access either from Living Room (swing door) and
Bedroom (sliding door). We love a fresh air but we hate this cigarette smoke.
Recently I installed an automatic door open/close actuators on all my doors
(both balcony doors and apartment entrance door) basically for the convenience.
Couple days ago I realized, I can detect neighbor presents on his balcony and
make my both balcony doors automatically closed on this event.
Just a regular Zigbee PIR sensor.
It is mounted under balcony rail on my side but facing neighbor's balcony.
I am in South Florida so temperature is not an issue. And the way how sensor
is mounted it is very well protected from rain.
As a former smoker (37 years ) I detest the smell of cigarette smoke. Guess that is how I went cold turkey. My 1 year old first born son was sitting in his high chair with a cloud of smoke from my after supper smoke. Told myself he didn’t deserve that.
Only problem with quitting is that everything tasted better. So I gained 25 pounds…
How about a device to discreetly aerosolize an odor even more unpleasant than cigarette smoke, aimed in the neighbor’s general direction (purely a coincidence, of course), coupled with the automation triggered by him going out on his balcony and closing your balcony doors?
Maybe he will decide on his own to smoke somewhere else…
Is SBD = Sliding Balcony Bedroom Door?
For this one I am using Autoslide Elite (https://autoslide.com/)
Integration with HE is two dry contact relays.
One is for full open/close and second one just a partial open for the cat.
For the Balcony Swing Door in the Living Room I am using DIY based on
Linear Actuator (controlled by ZEN-16). This door is equipped with very strong
auto close spring which I am not allowed to touch and/or modify.
Linear Actuator does a very nice job.
And for the Apartment Entrance Door I am using very nice looking and
very well designed Open Sesame door operator (https://www.opensesamedoor.com/).
This one is a bit pricy but I negotiated more than 50% discount.
Integration with HE is just one dry contact relay.
I was at Haunt convention (think Halloween attractions) where a vendor had a disturbing array of scents. Curiosity led to sampling, which led to wretching.
Dispensing metered doses to precise locations is the tough part. For legal reasons, I leave this as an exercise for the audience.
I think you're going to have to get more creative than looking for an off-the-shelf z-wave/zigbee device to automate the spraying of a liquid that smells like farts every time your neighbor goes onto his balcony to smoke.
Surely an engineer like yourself can come up with something.
I don't have a problem to come up with idea how to implement this.
But I am to...o lazy to physically build such a device.
Plus (or minus) all potential legal problems ...

to pull, an 
to run under a chair, or a 
to croak?
