To create separate thresholds for different voltage and temperature sensors (or a group of sensors), you must create groups by using appropriate matching criteria.

Device-level threshold values can be set from the Polling and Threshold window, under the Threshold tab. In the Polling and Threshold window, navigate to SystemResourceGroups > Device > Settings > Environment, and set the required threshold value.
Instance-level threshold values can be set from the Polling and Threshold window, under the Threshold tab. In the Polling and Threshold window, navigate to Temperature Sensor > Voltage Sensor, and set the required threshold value.
Also priority has to be set, with custom group taking higher priority than the default groups. The threshold values for a group which has been assigned higher priority take precedence over the others.
When a group’s Voltage or Temperature threshold setting is removed, the group’s instrumentation too should be removed.
