    Please explain how a smart meter could determine even whether a TV was connected much less the kind (brand? model number?) of TV.
    These days electronic devices use switch mode power supplies, usually with capacitor input filters (and soon, unity-power-factor style input stages), which all look much the same to the power source.
    Also power companies control individual loads in a home such as an off-peak water heater (or soon an airconditioner load on a hot summer afternoon), not the entire domestic load.
    How can one infer disease from a load profile?
