Valid comparison operators are:
|
||||
|
||||
- equal to `==`, unequal to `!=`
|
||||
- less than or equal to `<=`, greater than or equal to`>=`
|
||||
- less than `<`, greater than `>`
|
||||
|
||||
Expressions are evaluated from left to right.
|
||||
The Item will be visible if any one of the comparisons is evaluated as `true`, otherwise it will be hidden.
|
||||
|

**Examples:**

If any one of the comparisons is evaluated as `true`, the Item will be visible, otherwise it will be hidden.
|

It is important to note that visibility may be determined based on only one condition at a time.
|

If any one of the comparisons is evaluated as `true`, then the Item will be visible.
|

Otherwise it will be hidden.
|

|

In the third example above, a control for a lawn sprinkler will be visible if it is Morning, *OR* if it is Afternoon, *OR* if the temperature is above 19 °C.
|
||||
Combining multiple conditions, for example Morning *AND* above 19 °C is not supported.
|
||||
To control visibility based upon combining multiple Items, or on more complex conditions, consider defining and using an additional Item that is set by a Rule.

To control visibility based upon combining multiple Items, or on more complex conditions, consider defining and using an additional intermediate Item that is set by a Rule.
|
||||
Rules have a rich set of features that can support more involved scenarios.
