* Less Than\
  Rule will be triggered if device measurement is **less than** defined value
* Less Than or Equal\
  Rule will be triggered if device measurement is **less than or equal** defined value
* Equal\
  Rule will be triggered if device measurement is **equal** defined value
* Greater Than or Equal\
  Rule will be triggered if device measurement is **greater than or equal** defined value
* Greater Than\
  Rule will be triggered if device measurement is **greater than** defined value
* Not Equal\
  Rule will be triggered if device measurement is **not equal** defined value
* In Range\
  Rule will be triggered if device measurement is **greater than or equal** to **Min** value **AND** is **less than or equal** to **Max** value
* Out of Range\
  Rule will be triggered if device measurement is **less than or equal** to **Min** value **OR** is **greater than or equal** to **Max** value
