Notification Blind Time

The Notification Blind Time is used to send the status (open / close) after a certain time. In this time interval, each detected status is counted by the status counter. When the time interval expires, the current status (open / close) and counter are sent to the keep-alive packet.

Notification Blind Time is useful when you are not interested in the events in real-time, but rather want to understand the "final" status of the sensor. E.g. if you install the sensor on a door, there might be a number of opens/closes in a single NBT. The sensor will not send an uplink for every event, but will send the final status of the sensor after NBT interval since the first event.
