High Tech Pet is proud to announce another first of its kind, state-of-the-art product. Our new WiFi Controlled Power Pet door. Like our best selling Power Pet door this new WiFi controlled version is operated by a pet worn, ultrasonic collar, including our MS-4, MS-5, RX-10 and BF-30 pet collars. In addition to all the great features of our Power Pet door, the new WiFi controlled models may be operated remotely via our iOS and Android smart phone app. You can open and close the door, set up the 4-Way access control and set the hold open time. Best of all, you can set an unlimited number of individual timers to allow your pet to come in or go out on the schedule you choose. The app also gives you a history of your door's operation by day, week or year and, if you choose, it will send you notifications if your pet is trying to come in or out when the sensor is off. The PX2-WIFI is our Large size door to accommodate pets up to 100lbs. For smaller pets up to 30 lbs., please choose our PX1-WIFI.
