It's not OT, but you shouldn't have piggy backed it.

I would use either an optical sensor pointed through the pot position
at about the 20% height level, or a strain gage scale under the entire
coffeemaker, calibrated for the tare weight of the equipment.

Remember that either approach will false-positive when people pick up
the pot to pour coffee.

Urns work better in this environment.
