Does anyone have experience measuring home electricity usage, perhaps using CT Clamps ? Searching amazon, it appears the EHEM1-LV Home Electricity Monitor units might be interesting: https://www.amazon.com/Eyedro-EHEM1-Home-Electricity-Monitor/dp/B00EP774LM?ref_=fsclp_pl_dp_3
It appears that they might send their data to some sort of centralized service. Rather hoping that I can get data directly from the devices.
Does anyone have experience with this ?
