knob and tube?

Will the Belkin Wemo light switch work with older knob and tube electrical wiring? I noticed in the install requirements that a neutral wire is required - if only two wires exist in my house I'd assume one is hot and one is neutral. Is this correct?

    That is an incorrect assumption. If you only have two wires at the switches, one is likely the hot, the other the switched hot to the load (light). A neutral is required. This device needs a tiny amount of power to run the device and thus needs hot and neutral in addition to the switched hot (should also have a ground). The electrical code has recently added a requirement for all switch locations to have a neutral as more smart switches are coming on the market. Contact a qualified electrician for help.
