Figure 6 – Last connection time in Kunak Cloud
The device must turn green or yellow (with warnings) indicating that is connected and checking the “last
connection time”. It can be read when the last connection was made.
Once the device has successfully connected to the cloud, it sends one measurement to Kunak Cloud before
start working at the configured sampling and sending periods. These values can be checked in the
dashboard. If the device has been switched off for a long time or the battery has been disconnected, the
sensors may require several minutes (between some minutes several hour) till the cartridges reach the
working conditions. If the values send by Kunak AIR Pro while the sensors are stabilizing are out of range,
the Cloud platform will invalidate these values.
Then, it is recommended to wait a from 2 hours to 24 hours (depending on the sensor) after the first
initialization to check the sensor readings. Every Kunak AIR Pro has been factory pre-calibrated before
shipping to guarantee the best accuracy as possible during initial deployments. However, a final local
calibration may be required to reach the best performance of the sensors.
While Kunak AIR Pro is turned ON and after switching it OFF, the user can access to Kunak Cloud to check
the data, connections, health of the devices, sensor readings, etc. Please, check that sensors readings,
battery and signal values, charge, etc. are within expected ranges to detect any anomaly.
Kunak AIR Pro must communicate its values to Kunak Cloud, but sometimes a connection may fail. In these
cases, the devices will store all the readings till a successful connection is achieved.
If the device status is “OFF” or “OFFLINE” in Kunak Cloud, wait until the next connection period and/or check
its last battery value. When the installation has been made under very low signal levels, (<-90dBm), the
number of failed connections could be higher than desired, but no data should be lost.
Be aware when analysing data that each sampling period is an average. It is calculated
from the last sample to the new one. The average timestamp is set at the end of the
sampling time.
If the sampling period is 5 minutes, Kunak AIR device will calculate the average, for
example, from 12:08 to 12:13 and the timestamp of that measure will be 12:13.
In order to offer the data with the maximum possible reliability, the device has a data discrimination
mechanism after a connection to the Kunak Cloud to prevent certain electromagnetic interference (EMI) that
can alter the data being sampled at that moment. Once the connection is made, the device will discard the
following data in the next 2 to 5 minutes. The range of discarded data, variates depending on the sampling
period and the sending period configured. The “Sampling period” and the “Sending period” can be changed
through Kunak Cloud. An example of how much time the data is discharged (Guard period) regarding the
“Sampling” and “Sending period” is shown below.
