Measurements and data upload
Measurement and data upload period The period for logging the measured values and uploading them to the portal is fully configured automatically via the portal, separately for operation with an external power source and batterypowered operation. SensDesk.com portal default values:
External power � Logging period (measuring, storing values in the internal memory): 5 minutes � Data upload period (connecting to the portal and uploading all logged values): 1 hour � Check period (NB-2xOUT brief query for output state changes): 10 minutes

NB-xxx devices product family

NB - Devices

Battery power � Logging period (measuring, storing values in the
internal memory): 15 minutes � Data upload period (connecting to the portal and
uploading all logged values): 10 hours � Check period (NB-2xOUT brief query for output state
changes): 1 hour
Only the Portal administrator may provides you other than automatic logging / Data update period settings (setuped per each device). Keep in mind device life time when powered from battery. Data upload period cannot be shorter than 60 minutes and the Logging period shorter than 5 minutes.
Periodic and non-periodic reading of sensors Sensors values are regularly read in the fixed Log Period, which is configured via the portal. However, in addition to the periodic reading, the values can be also read if the following happens: 1) The device is powered up by connecting the battery or an external power supply 2) The button is pressed 3) If the SafeRange is exceeded at the moment of periodic reading, the measurement is repeated
after the Delay interval
Periodic and non-periodic data upload Sensor values are uploaded to the server periodically in the fixed period, which is configured via the portal. However, in addition to the periodic upload, data can be also uploaded if the following happens: 1) SIM card is inserted 2) Device power is connected or changed 3) The button is pressed 4) SafeRange is exceeded (if the Delay is set, then only after the Delay elapses)
SafeRange � range of allowed values SafeRange is configured in the portal independently for each sensor. Whenever the measured value passing by this range, a message to the portal is sent (even out of the Data Upload period - default 10 h). To extend life time of the device powered from the battery, sensors are read only in the Logging period (default 15 min). With the exception of SD-2xIN, sensors are NOT read at other period. If a Delay is set together with the SafeRange, the repeated measurement is performed at the next Logging period, and an Alarm is raised only if the repeated measurement is also out of the SafeRange.

Hysteresis / Idle range (sensor value)
The Hysteresis setting defines a tolerance range for suppressing alarm alerts. The function prevents multiple alarm alerts (too many emails from the portal) if the reading oscillates around the specified threshold. The hysteresis is configured independently for each sensor.

The figure demonstrates two cases. Without the hysteresis idle range of 5 �C, the alarm raised in point 8 would end in point 9; however, the hysteresis function keeps the alarm active until the temperature reaches the upper limit of the tolerance band (point 10): 5 �C + (�15 �C) = �10 �C.

� Hysteresis = 5 �C � The unit sends 3 Email (SMS) messages. Alarm active in points 0..4, 8..10, 12 and beyond.
� No hysteresis (0 �C) � The unit sends 8 Email (SMS) messages. Alarm active in points 0..1, 2..3, 8..9, 12..13, 14 and beyond.

In determining when the Alarm ends, the Hysteresis value applies. The end of an Alarm is only notified when the measured value is well within the SafeRange. However, the value is only read according to the Log Period.

Description of HW elements

LED indicator (Status)

The blue LED gives a quick status indication for debugging and troubleshooting. It can indicate these states:
� Short flash � reading of sensors and inputs
� Rapid flashing � registration to the NB-IoT network

Power 5V

Status Setup
NB-SIM

� Continuously on � communication over the NB-IoT network, data transfer

When power is connected to the device, the indicator briefly lights up to indicate modem initialization and 1-Wire sensor detection. Then, it quickly flashes as the device connects to the network, and lights up whenever the device communicates with the portal. It also briefly flashes when the 1-Wire sensors or the WLD cable state are being read.

Setup button The button is used to send values to the portal immediately and to detect sensors. � Press � sensors are detected and data are sent to the portal � Press for longer than 10 s � reset to factory defaults

Setting up the device
1) Attach the external antenna 2) Connect 1-Wire sensors (NB-2x1Wire only) 3) Insert SIM card 4) With a slight force, pull out the insulating strip that insulates the battery from the contacts 5) Connect the external power supply and wait until the device connects to the operator's
network (i.e. until the blue LED turns off). Depending on the network and device configuration, this can take up to 20 minutes (when the device is first connected to an operator's network, including in a new country or region). During this time, do not disconnect external power to avoid battery drain. 6) Default portal where are devices connected is www.HWg-cloud.com. To install new device are 2 options:
a) You have existing account on the HWg-cloud and you would like to adopt new device to this one account. (See page 9)

Remote monitoring device for connecting external detectors to 2x DI (Digital Input). To each DI input you can connect a door or window contact, a PIR motion detector or a smoke / gas detector with a dry contact (relay) output.
Pulse counter (S0) on each DI input Advanced feature of each DI input is 4bytes pulse counter for counting pulses. To each DI input you can connect energy or water meter with pulses (S0) output. Only pulses longer than 20 ms are detected. Due to high energy requirements of S0 outputs, external power is required for reliable pulse counting. When device powered from internal battery, reliable operation cannot be guaranteed.
Alarm state The input mode (Alarms or Counters) can be changed in the Digital Input configuration at the portal using the "Alarm level" parameter. If the "Not Defined" option is selected (default portal configuration), DI input is in pulse counting mode and 0/1 state is communicated only in the regular data upload period. When Alarm level = 1 or Alarm level = 0, DI input is in the Alarm mode. The input 0/1 state is communicated in the regular data upload period as well as whenever there is a state change. To comply with the transmission limit, the device will send no more than 3 alarms per 10 minutes. Frequent state changes can have a significant impact on battery life. For battery operation, wiring cables should be as short as possible to avoid false pulses.
LED indication The default mode is the counter mode (i.e. Alarm level = Not defined). When DI input is activated (=1 / contact closed) and the device is powered from an external adapter, the respective green LED lights up. The LEDs are inactive on battery power.
