That is an interesting way of making an automatic door.

well thank you I have to close it at night by empty the water bottle back to the tank
but we are here at night time I could put a pump in the bottle and have another timer set at 2 min to pump
the water back
that why you need a digital timer the m/timer only uses 10min bites

take care
