    The documentation that SDG&E sends, ad well as their website, state that the new smart meters “transmit” usage data to SDG&E.

    But nowhere do they say how that transmission is made. Wireless? Over the power lines? Is it encrypted? What personally identifiable information is contained in the transmission? And does the transmission work both ways?

    I have sent these questions in to SDG&E, and of course, got zero response.

    Does anyone know the details?

    I did look into this quite a bit about a year ago. My recollection is that it is limited range wireless and that the signal is sent to a “substation”. These substations gather the data from the neighborhood and send it to HQ…

    I could be wrong, but that’s what I recall.
