My point was, indeed, that Sense doesn’t need to communicate with Z-Wave and that if there existed, by the likes of Belkin or TP-Link in the Wemo/Kasa realm a wifi-based 240V high-current smartplug with energy monitoring capability then Sense would probably include it in the integration. Beyond that I believe they have better things to do.
@kevin1’s point, as I interpret it, is that when you add the latency together (Z-Wave + WiFi) you can’t expect Sense to perform adequately, as needed for the disaggregation … which is the motivation to include it in the first place.
I’m trying to do an apple$-to-apple$ comparison when I suggest considering 2 x $150 GE-Enbrighten 40 Smart switches versus an additional Sense Solar @ 2 x $175 … obviously you don’t get smart switching with the Sense but you do get plug-n-play energy monitoring at even higher resolution than any existing smartplug. I’ve maxed out on smartplugs on my main Sense and I’m starting to spill-over to have additional ones on the secondary Sense … which is monitoring my hot water tank and air conditioner.
