With change node, it is possible to save messages that are coming out of the nodes and reuse them.
...
This article will cover knowledge about flow and global objects.
A node used to set the message as a variable is a change node.
...
The value of the variable (var_01) will be overwritten and the value of the original message will be passed on without modification.
In For example, if the message with the value “100” will come into a node, it will be saved as a value of a variable.
(2) To change the incoming message into a variable, the “Set” rule has to be used in the other way
...
Now the output of the change node will be the value which is stored as a variable (var_01).
Every incoming message will be changed into a value of a variable.
Checking the value of variables
...
Value The value of the flow is shown in the “context” tab.
...
In logic when the presence detection has to trigger a value from the Intensity Scheduler (ES_CCT node).
...
Turning ON daylight harvesting with at a scheduled time.
