If a sensor is not configured correctly, then it will need adjustment. Changing the configuration is done through the azeti Control Panel.

In this How-to, we will use a temperature sensor as example.

 Example Sensor Configuration
<sensor sensor_id="Temperature">
    <sensor_class>temperature</sensor_class>
      <unit>C</unit>
      <state_evaluation_expressions>
      <state_evaluation_expression>
        <expression>value &gt; 40</expression>
          <true severity="200">CRITICAL</true>
          <false severity="0">OK</false>
        </state_evaluation_expression>
        <state_evaluation_expression>
        <expression>value &gt; 35</expression>
          <true severity="100">WARNING</true>
          <false/>
        </state_evaluation_expression>
      </state_evaluation_expressions>
      <sensor_gateway sensor_gateway_id="gw_X20AI8321_analog_inputs">
      <demux>
        <keys>
          <key>5</key>
          </keys>
        </demux>
        <calibration_rule>
        <offset>-52</offset>
          <raw_result_factor>0.0061037018951994</raw_result_factor>
          <rounding_precision>2</rounding_precision>
        </calibration_rule>
      </sensor_gateway>
    </sensor>


In this case we will change the rounding precision from 2 to 1, because there is no need to see the degrees in such detail.

Step-by-step guide

  1. Go to Config/Provisioning → Sensor Templates → Site Templates
  2. Click on Edit next to the correcponding Site Template
  3. Toggle SU/Normal Mode and clkick on the +Sensors to colapse it
  4. Click on the desired sensor. In this case Temperature
  5. In the field sensor.sensor_gateway.calibration_rule.rounding_precision.value change the value to 1
  6. Toggle SU/Normal Mode and clkick on back
  7. Now the Site Template needs to be redployed for the changes to take effect → How to deploy a Site Template



Raw Result Factor is a calculated value, depending on the values we get from the I/O module and the temperature range the sensor can measure. In this case, the I/O module gives a value ranging from 0-32767. This needs to be divided by the range the temperature sensor can measure (-50-150°C).
