Can I automatically lock the door at night?

Yes, the petWALK pet door offers you two options:   About timing. While controlling the door by using the motion sensor you can set the outlet time freely. When controlling the pet door with RFID chips, you can specify the outlet time for each of your pets individually.    About dawn control. The petWALK pet door has standardly integrated a dawn sensor. You can individually set the dawn value to set the time, when your pet door should remain closed. To ensure that your stray cat can come home even after programming a dawn value, you can allow this on your individual level.
