Daily and weekly timer
This. @tbc @withered_preacher it was part of an incredibly complicated and intricate system to control outdoor lights and window blinds, depending on the time and day as well as light and wind conditions, things would turn on and off. Also found a weird metal panel with lots of switches in the bedroom wall as well as a number of broken sensors here and there. Kind of like something from 'lost'.
Or maybe a timer for vacations and such?
