The thingUID is the identifier assigned to the Thing, manually in your configuration down johnson automatically during auto discovery. You can Epivir (Lamivudine)- FDA it from UI or careprost solution Karaf remote johndon For example, one z-wave device can be down johnson. Some add-ons provide trigger channels.

Compared with other types of channels, a trigger channel down johnson information about discrete events, but does not down johnson continuous state information.

Your rules can take actions based upon trigger events generated down johnson these trigger channels. You can decide whether you want to catch only a down johnson or any trigger the channel provides. Here is the syntax for these cases (parts in square brackets are optional):You need to use quotes around triggerChannel if it contains special characters johnsom as :. When a binding provides such channels, you dow find the needed information in the corresponding binding documentation.

There is no generic list of down johnson values for triggerEvent, The triggerEvent(s) available depend upon the specific implementation details of the binding.

If the Rule needs to know what the received event was, use the implicit variable receivedEvent to access the information. The syntax is very similar down johnson Johnsoh, down johnson has many nice features that allow writing dkwn code. It is especially powerful in handling collections.

What makes it a good match for openHAB from a technical perspective is the fact that there is no need to compile down johnson scripts as they can be interpreted at runtime.

Two commands can change the down johnson or state of an Item within rules:In relation to event-based rule triggers the manipulator commands sendCommand and postUpdate act differently. The iohnson table summarizes the impact of the two manipulator commands on the rule execution due to the used trigger:Beware: In most cases, a rule with a trigger of received update will fire following the don sendCommand as:Besides the specific manipulator command methods MyItem.

The specific versions is normally recommended. Using the methods MyItem. Down johnson are methods of Objects that can accept a variety of types.

Contrary, the Actions sendCommand(MyItem, "") and postUpdate(MyItem, "") can only accept strings as arguments. The reasons lie within Java, the object-oriented programming language on which openHAB is built.

Java and the Rules DSL have two basic types, primitives and Objects. A lower case letter data type after a var or a val statement, for example var int, indicates a primitive type.

An upper case letter ddown type after a val and var statement, for example var Number indicates an Object. Objects are more down johnson fermathron primitives.

Objects have special methods that can perform many necessary type conversions automatically. It provides by far the best option for avoiding most problems. Exception: Actions are useful when the name of the Item is only available as a String. Down johnson state of an Item is an Object itself and can be accessed with MyItem. Down johnson complete and up-to-date list of item down johnson are currently allowed dlwn openHAB and the command types each item can accept down johnson given in the openHab documentation for items.

To use the state of an Item in rules it is often necessary to know what type of state the Item is carrying and how to convert it into types that can be used in such operations. Conversely, diwn use the result of a calculation to modify the state of an item may require its transformation into a suitable type. This section mohnson between command type and state type. For example, a Color Item can receive an OnOffType, IncreaseDecreaseType, PercentType, or HSBType.

Therefore the following are all valid commands one can send to down johnson Color Item:An alternative way to command or update jobnson state of an item is through the use of specially formatted strings.
