Why does my Smart Autodoor not open when I think it should on light mode?

To prevent the door from opening unintentionally in response to torches, headlights, security lights and so on, the light level detected must remain above the level set for opening for 15 minutes before the door will open.

In the mornings you may notice in the Omlet App that the current light level reading is reported at a level higher than the level set to open the door, but the door is still closed. This is completely normal. Wait for 15 minutes, and you should see that the door has opened within that time.
