I see, thanks for the explanation. The above implies that: a) the timer is restarted when the room light level goes above the specified, so your 1 minute starts from zero if you turn the ceiling light on in the room. b) suppose the LED is off, the ceiling light is on, and the target light level is very low. Once you exit the Light Sensor panel, Lanterne will not turn the LED on even if you turn off the ceiling light. At least this is what I'm observing. Correct?
