FurnaceClip

Our furnace is a like a beast residing in our basement. When it is “on”, the house has a bass hum and you can tell something is on fire, not far away from where you are.
Couple this ominousness with a curiousity to know about when the furnace is coming on and for how long, and you’ve got the background for my FurnaceClip.
(This kind of information can be useful. A few years ago, our furnace was coming on quite frequently in the summer. It didn’t seem right. We came to find out a few years later that our hot water tank controller was defective. I can’t tell you how much fuel and cash we wasted not catching that problem sooner).
I’ve tried a few approaches over the years and have an iteration now that has been working for quite a few months and (finally) accomplishes my goals.”
