I used to use it when I knew a device was off, but sense reported it as on. For instance, Sense reports my coffee maker on every day in the evening (despite being on a remote switch that kills it’s power at 9AM, I don’t need it re-warming the water for 21 hours when it’s not needed). This is where I used to use that button. In reality, Sense is confusing the toaster over with the coffee maker. Previously they’d been independent.
I just want to remind Sense that the device is not on.
