@ixu, covered a lot of the bases, but I’ll give you a little more food for thought. One Kasa sample (every 2 sec) is probably longer than the window the Sense “transition detector” built into the Sense monitor is looking at. That makes it pretty much impossible to use the data coming in from the Kasa for filtering or noise cancelation.
And as an electrical engineer, I don’t have much confidence that current Sense capabilities can “identify” on and off signatures for AVRs or OLED TVs for a several reasons:
- Sense relies on transitions to detect on and off events. Most modern DC power supplies obscure their on and off events via energy storage (capacitors) and switching electronics. Plus they really don’t have a consistent phase space fingerprint.
- Even if Sense could detect the on and off, it would be poor at estimating power consumption since power utilization of these is volume-dependent and AV content-dependent.
- Content dependent power usage for video is anything but predictable… Consider this
