+- GPIO2 used as input -> must be high during startup
+- PCB Solution: cut trace to GPIO2, solder bridge to GPIO16
+- -> disadvantage: GPIO16 is not interrupt capable
+
+
+### FSM 2 - to do
+- stairway light switches off after timeout
+- switches concurrently on again if sensor is still high
+- desired behavior? Defective Sensor would cause continuos animation
+- edge detection / interrupts as solution ?
