Another suggestion might be to utilize the smart plugs for circuits that are dedicated to a single 120V device instead of consuming a CT sensor. Such as Code dictated devices like refrigerators, dishwashers, garbage disposals, microwaves and even the small appliance circuits if there aren’t too many of them. Only possible caveat to this might be wifi signal strength behind appliances or inside cabinets. I tried to use a smart plug for my fridge and it would frequently disconnect because I think there are too many obstructions between my access-point and back of the fridge.
