The following objects can be tracked:
To allow the plugin to keep track of the object state changes, automatic reporting for the object type has to be switched on. You can configure the automatic reporting settings in the Communication tab of the Controller Settings screen under the Configure menu.
In stead of reporting every change, you can also insert the appropriate object reporting command at strategic places throughout your schedule. This second option is usually preferable for variables and sometimes also for flags. These objects change frequently which would result in a lot of reports, possibly flooding the serial connection. However most of those changes are for internal operations only and don't need to be reported.
Example:
Var #29 (HVAC Mode) = 2 Controller command: Report status of all variables
Due to their nature, also analog inputs values will frequently change. It is probably better to switch off automatic reporting for this object type and setup a periodic event that triggers the report every minute.
