For specifics of individual devices, including any differences in the measurement period, battery life, and so on, see the respective device page.

Measurements and data upload

External sensors measurement and data upload periods
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 battery-powered operation.
External power – default SensDesk.com portal values:

• 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

Battery power – default SensDesk.com portal values:

• 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 provide you with other than automatic logging / Data update period settings (setup per each device). Keep in mind the device’s lifetime when powered by a battery.
The data upload period cannot be shorter than 60 minutes and the Logging period shorter than 5 minutes.
Periodic and non-periodic readings of sensors
Sensor 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 also be read if the following happens:

1. The device is powered up by connecting to 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 a 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. safe range is exceeded (if the Delay is set, then only after the Delay elapses)

Safe range – range of allowed values
Safe range is configured in the portal independently for each sensor. Whenever the measured value is passing by this range, a message to the portal is sent (even out of the Data Upload period – default 10 h).
To extend the lifetime of the device powered by the battery, sensors are read- only in the Logging period (default 15 min). With the exception of SD- 2xIN, sensors are NOT read at any other period. If a Delay is set together with the safe range, 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 safe range.
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 or SMS 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 portal sends 4 Email (SMS) messages. Alert is sent with the beginning and end of Alarm State (points 4, 8, 10, 12)
• No hysteresis (0 °C) – The portal sends 8 Email (SMS) messages. Alert is sent with the beginning and end of Alarm State (points 1, 2, 3, 8, 9, 12, 13, 14)

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.

Alarm status notification based on a Delay value:

• Blue: Delay = 0
• Yellow: Delay is non-zero

To increase battery life, be careful when setting the SafeRange and Hysteresis values.

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
• 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

Status LED signalization

• Short blinking [2–5 seconds] is a standard communication with the NB-IoT network
• Short blinking [2–5 seconds] when the “Setup” button is pushed is standard communication with the NB-IoT network
• Initialization blinking [30–240 seconds] NB-IoT network Initialization process

Installation process
A standard subscribed version of the device is already preset for the local NB IoT network/provider. No configuration is needed.
Connect external power (remove plastic stripe disconnecting the internal battery). First approx. 20 minutes will device search for existing NB-IoT network coverage and connect
to the predefined portal (HWg-cloud.com).

• First 4 min: Blue LED activity = Searching for NB-IoT network (Fast blue LED blinking, short pause, and repeat again)
• First 5–20 min: Blue LED activity = First start & Initialization with NB-IoT network (up to 20 minutes). Once completed and the device stays in the same location (not moved) no need to repeat Initialization again.
• First 5–20 min: None Blue LED activity = Compatible NB-IoT network not found, consider the possibility there is no compatible NB-IoT network signal in your location. Searching for the NB-IoT network will be tried again next hour several times with prolonged intervals.

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. Install a new IoT Monitoring device on the default portal HWg-cloud.com (+ migrate to another portal).

NB-Devices models and their specific features

NB-2x1Wire

A device for connecting external sensors of Temperature, Relative Humidity, Voltage, or other values via the RJ11 1-Wire (UNI) bus. 2 RJ11 ports allows connecting several external physical sensors to measure up to 4 sensor values simultaneously.
The sensors are detected whenever power is connected to the device or the Setup button is pressed.
The device can be powered from an external 5V adapter, from its internal battery, or using a combination of these. With a single connected Temp-1Wire IP67 temperature sensor and the default sensor reading and data upload periods, the battery lasts up to 3 years. When using 1-Wire UNI sensors, either the sensors or the NB-2x1Wire device should be powered from an external adapter because such sensors significantly reduce the battery life.

External sensors

Port/connector| Port1, Port2 / RJ11 (1-Wire, 1-Wire UNI)
What can be connected| 2 ports for external sensors. Up to 4 sensor values in total.
Sensor types| Only sensors by HW group s. r. o.
Sensors / distance| 4 values, max. 2 probes per port (max. 60 m total lengths per port)
Alarm LED| Alarm Port1 – Alarm SENS – lights up if the sensor is in alarm – on external power only

NB-2xIn

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
An advanced feature of each DI input is a 4bytes pulse counter for counting pulses. To each DI input, you can connect an energy or water meter with pulses (S0) output. Only pulses longer than 20 ms are detected. Due to the high energy requirements of S0 outputs, external power is required for reliable pulse counting. When the device is powered by an 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 the 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.

DI – Dry Contact Inputs

Port/connector| I1, I2 / terminal block ø 2 mm
Type| Digital Input (supports NO/NC dry contact)
Sensitivity| 1 (On) = 0 – 500 Ω
Max. distance| Up to 10 m
Counter sensitivity| 20 ms
LED| 2× green – input contact closed – on external power only
Pulse counter| Ext. power required for reliable pulse counting – S0 = min 5 V / 2 – 10 mA

NB-2xOut

IoT monitoring device 2 DO (relay outputs) controlled from the portal over the NB-IoT network. It can be connected to any SensDesk Technology-based portal.
To reduce power consumption (when running from the internal battery), the device uses internally latching relays. To increase reliability, internal relays are energized periodically every 10 minutes.
When powered from an internal battery only, the estimated battery life is around 2 years.
Note: The device is not suitable for mobile applications due to vibration issues (in cars for example).
LED indication
When powered from an external adapter, output states are signaled by a green LED when output = 1.
The LEDs are inactive on battery power.

Relay outputs

Type| Latching (bipolar) relay
Connector| Terminal block
Rating| Max. 500 mA at 125 V AC, 1 A at 30 V DC
LED| 2× green – output contact closed – on external power only

NB-WLD

Water Leak Detection unit with 1 zone input (external WLD Type A moisture- sensing cable).
Lenght of the external cable can be max. 60 m (any combination of WLD sensing

• non-sensing prolong cable).

Flood detection is performed every 5 min. (15 min. when powered from the battery). Estimated battery life with 15 min. detection is 4 years.
LED indication
If the cable is flooded or disconnected and the device is powered from an external adapter, the red LED lights up.
Note: The LED is inactive on battery power.

WLD cable

Type| Moisture sensing cable
Connector| Terminal block
Sensor states| 0 = OK, 1 = Flooded, 2 = Cable disconnected
