track TV usage
simple timer which tracks on vs. off
no other measurement. TV is treated as by definition unproductive and cognition-sucking time
track how long the kettle spends boiling water
start is defined as "turned on from off"
done is defined as whistling
finished is defined as the action of turning off from on
how do you sense how much water gets poured in
doesn't really solve a problem other than measuring what something (boiling water) happens in parallel to something else
