Might be able to use a flipper zero as the sensor, if the cats are chipped. Then you'll have data to catch any unusual usage, like a urinary blockage, before it

Might be able to use a flipper zero as the sensor, if the cats are chipped. Then you'll have data to catch any unusual usage, like a urinary blockage, before it becomes a serious problem! At that point you're a smart switch and Home Assistant script away from fan control.
- kentonv 2y agoGarply had a blockage once and he did a remarkably good job of communicating the problem to us directly!
- allenrb 2y agoAs a fellow cat person, I feel pretty confident interpreting what’s being implied here. :-) Beautiful home and contents, btw! It seems expensive but more than a few folks would have spent the same money on “nicer marble” or something.
- kentonv 2y agoHeh, I actively dislike "nice marble" or anything that just looks expensive without providing any functional benefit.
- ahaucnx 2y agoI would recommend to use an TVOC sensor that detects smell very easily and then automatically switch on a fan. Could be a fun project. Just need: - TVOC sensor like the SGP41 - ESP32 microcontroller - Electric Relay
- teruakohatu 2y agoInteresting idea. Do TVOC respond with enough signal to low level aromatics verses all the particles from cooking or pollution?
- amluto 2y agoI’m highly unimpressed by my couple of SGP41 sensors, but they would probably work for this application.
- trebligdivad 2y agoI did wonder where the network connections were going into the cat areas!
