There are three digital inputs on the board, these can be configured as NO or NC individually (before shipment).
The first of the digital inputs, A0 or P2, can be used to wake up the device in NC or NO state (if configured).
The other sensors state can not be used to wake up the device and initate an alarm. It is therefore normal that there is some latency delay between the change of the digital input state, and the signal to the cloud and any subsequent alarm. That may not be suitable for applications where a near real-time alarm is essential, for that purpose, please use the P2-input.
