Is there a way to take two temperatures…

Temperature parameter 50, For example 80 degrees

Temperature parameter 51, For example 90 degrees

And have parameter ID 52 be the average of 50 and 51?  For example 85 degrees.

Hi Ed,

If param 50 and 51 are polled via SNMP you can create a QAction that gets triggered by the two parameters or after the respective SNMP Group.
Inside the QAction you can retrieve the two values, calculate the average and set the result in a new parameter.

If the parameters are not SNMP, still the QAction would be the way to go (parameter 50 and 51 can trigger your QAction)
