I'm trying to create a pi notification for when a tag contains a certain string it will trigger a notification.
The Attribute is called "Operation" and related pi tag is of pointtype string. This pi tag does not contain just a single word like "open" or "close", It has values like "closed_23042019". And they are not digital states.
So in pseudocode;
if Value ("Operation") Contains "closed_" for 30 minutes;
Trigger Notification .
How can i get the Trigger Condition to look for "closed_". And if the PI tags still has the same value of "closed_" after 30 minutes trigger a notification.
I currently have
TagVal('Operation','*') = "closed_".
True for : 30 minutes
