I have a switch node with different output depending on temperature range. Like 0-5, 5-10 and 10+  
Now there is output when the temperature changes from 6 to 7 and 7 to 8. I want outputs only when there is a change in range. When the temperature changes 5 to 6, or 10 to 11. Is this possible?

If you use an RBE you can block messages unless they change.
