QUESTION: How would you write the instructions to turn the tapes OFF?? I have a similar set up and live in the NorthEast (NYC-area) . Like you describe, my weather station is also very close by and gives me accurate info. I set up a similar set of commands to turn my snow-melt heat tapes ON. But I didn't want to use the "ELSE" to turn the tapes off, because I do NOT want the tapes to shut off immediately when the conditions are no longer true, ie, as soon as the snow stops. I want the tapes to stay on for an additional 12 hours after it stops snowing to make sure all the accumulated snow has melted. Ideally, I'd like to have some commands that say "if the heat tapes are currently on, but it's no longer snowing anymore, and there's no snow in the forecast, then turn the tapes off in 12 hrs". But if I add a "wait 12 hrs" to a THEN or ELSE statement, then every 5 or 10 min, when it polls the weather station, it will start a new 12hr countdown. I feel that that is asking for trouble. Ideas anyone???? Many thanks.
