@ramon,
Love your intrepid thoughts. It would be cool to have a PC/Mac or Arduino based responder/proxy that looks like an HS110 to the Sense, and configures like an HS110 to the Kasa app, but pulls data from other sources like:
- Tesla chargers / Tesla API - the API does give instantaneous charging info
- HVAC systems, especially 240V systems that have some means of reporting via API (both my Ecobees and NuHeat thermostats have similar APIs)
- Some big computer-related power supplies and UPCs have power delivery reporting
Wishing you the best of luck with your endeavor - keep us informed. We may be willing to test.
