Why can't the gateway and APP monitor the momentary opening and closing of the door with S4, which is possible only when the door is opened for more than 1 second? What is the broadcast interval of S4?
The broadcast interval of S4 is 900ms. According to this broadcast interval, the momentary opening and closing of the door can not be detected, and the use of S4 requires a longer time of opening and closing to be monitored. Combining the broadcast interval of S4 and the scan and upload interval of the gateway, it is recommended not to open and close doors and windows multiple times within 1s.
