First attempt at using PLEG. Using a very simple procedure with PLEG but I’m missing something. Will not work as a trigger for a scene. also I see in the status report Conditions state is staying at null which I don’t think is correct. Missing something simple but can’t see it

Temp is a trigger so will be true or false. HeatOn1 is a property so can be evaluated in a condition. You need to remove the quotes from your condition expressions.
When you first setup a trigger with a test value (like < 9.7), it will stay at null until the test is passed. I usually set the value so that the trigger fires and then reset it to the value I want.
Thanks for the feedback. When I remove the quotes from “Temp < 9.7” I get an error message of invalid expression operation in Temp <9.7 when vera restarts. Suggestions?
Thanks
Unless you have changed it, Temp is a trigger. It will be true when the Outside Tap temperature goes below 9.7 degrees. Your condition statement should be just Temp. Alternatively you could write the condition as HeatOn1 < 9.7.
Does that make sense? Triggers are true or false. Properties are quantities so can be compared with constants.
The light just went on (in my brain) Thanks for taking the time to explain. I’ve got it now and the logic makes sense (finally).
Thanks for helping out a newbie.
