I’ve had three banks of multiple lights on each identified by our Sense and I’m happy with that. One set has a mixture of 6 CFL and LEDs, another set is 10 CFLs and a third is (I think) a mixture of 6 CFLs and incandescents. We have very few switches in the house that have only a single light on them and LOTS of light banks still to identify. As CFLs burn out we replace them with LEDs (as we did with incandescent to CFL years ago) so we are probably presenting Sense with a moving target. As such I don’t expect much from the Sense in that regard as we aren’t really following the rules.
That said, Sense is providing a benefit that I never expected. I bought the Sense to track usage on large consumption devices and in that it has done well for us with some 33 devices found. Yes, there are many more to go including my Tesla Model X, which was the primary reason I bought the Sense, but even the detection of the lights have served a purpose. I’m crazy about turning lights off when not in use, my family not so much. I love that I can sit at my desk and see even the few lights that have been detected whether they are on or off. One of the three sets are on an Insteon switch and so if I find that they are on and I know no one is in the room, I can switch them off without even having to get up from my desk. And if I have to get up for the other two that’s fine also, although I will be putting another one of the three sets on Insteon soon.
