Temperature difference rule not longer starting fan

For starters, I would write a way to prevent the rule from triggering every three minutes when the temperature still reports a delta of 3.5 degrees and is still in a wait for timeout status. You likely have an instance of the rule running for each of those trigger events in your log. Use private boolean is false in the required expression in addition to to the date constraints. Have the first step of the rule turn the private boolean true, and the last step should be private boolean false.

@user538

This is good advice. Just wanted to add that recently @bravenel recommended the use of a conditional trigger over a required expression for a similar use case; that thread also has a simple example of a conditional trigger that is applicable to your use.

Preventing trigger repeat

Instead of Required Expression, just use Conditional Trigger. Simpler, and more reliable.
