I am looking for something exactly what you guys are explaining. I want to be able to monitor, or at least be alerted if my Hot Spring's temperature ever drops below a certain temp. If the power ever trips, I would hate it if my spa ever got too cold and froze, destroying the whole thing. Ideally, I would love for some type of interface (Ardunio or other) to be able to text or email me if this happened. Reading directly into the board would be great.
