Description
successfully bound Breath to my Klipper Printer, which was very easy to do, well done!
.) breath started as it should do when I set Bed Temp to a level above both thresholds, but about 2mins after printer reached bed temp breath stopped for around 20 seconds and then continued heating ? .........why does it interrupt?
.) print finished, bed temp set to 0:
Breath stops immediately, but it should continue with the filter fan until chamber temp goes below a specified threshold?
this would be an additional safety feature as heating element is actively cooled down, also fumes from ABS/ASA would be filtered better as they are still present after print stop

Research direction
Start by tracing the existing bed-temperature threshold handling and the fan-stop path described in the issue. Check how chamber temperature and a configurable post-print threshold are represented, and investigate the reported interruption during heating. Done means the fan remains active after bed temperature reaches 0 until chamber temperature falls below the specified threshold.
