I had a chance to do another Sense experiment today. Yesterday, I replaced our Sharp under-counter microwave oven. The existing one was only about 10 years old, but seemed to take longer to heat things up and had a portion of the interior from panel that appeared to be melting. Because it had to fit in a fixed sized island opening without a faceplate, we had to replace with the same exact same model (according to my wife, Sharp has some patents on under counter models and manufactures all of them in the world, even for pricey brands like Viking). My first question after the replacement install was whether Sense would immediately detect the new microwave or whether another round of training would be needed. Any guesses ?
Here’s a hint - even though it’s a new microwave oven, it doesn’t have the new inverter-type power supply. The microwave working bits, from my tear-down, are old school, straight out out of the 1970s: a huge 15 pound high voltage dual coil transformer, an enormous capacitor, and the microwave magnetron. In fact, the only concession to modernity vs a 1940s microwave generator is the solid state diode on one leg of the capacitor.
So if you haven’t guessed, yes Sense immediately picked up the new oven, without any hesitation. The physics doesn’t change !
ps: After a few normal heating cycles, I’m going to look at Power Meter waveforms before and after to see if there was any power usage differences before and after.
