where is the inlet of the sensor?
if it is near the bottom of the unit it will be detecting the co2 that has pooled on the top of the fermenter.
co2 is heavier than air and will sit in that lid as it cascades out of the airlock.
17 days should be be long enough to finish a wash and be cleared nicely.
do you keep it at a constant temp? (is that a insulated box or old fridge in the background?)
it's probably better to go off hydrometer readings than perceived activity or a co2 sensor.
hopefully the fermenter is jammed full of co2, as this protects the wash from infection.
no bubbling of the airlock does not mean the yeast have finished cleaning up their own shit (as Julius Sumner Miller probably didn't mention :smile: )
