The 3 outlet version, the KP303, doesn’t have the hardware to do power monitoring. One of the big challenges when Sense first integrated with smartplugs, was that there were very few that had the combination of built-in power monitoring and WiFi connectivity. Many more are available today, but all “talk” via different protocols, most of them proprietary.
One interesting thing about the TP-Link interface - users have been able to write an interface that talks to the Sense monitor from HomeAssistant, so power info in HomeAssistant can be passed to Sense as if it was one or more HS110s.
