PLC for lighting control?

Rick Mann

I've been experimenting with various home and building automation (ZigBee, Z-Wave), and feel that some form of robust (*not* X-10) power line control would be superior.

TI (and others) make PLC chip sets, but they all seem to be geared toward automatic power meter reading. Are these solutions appropriate for lighting control (specifically, for embedding in a typical decora wall switch)?

It's acceptable if interfacing with these PLC systems requires installation of special hardware in the building circuit breaker panel.

    Hi Rick,

    The PLC solutions for G3 and Prime at TI have been centered around power meter reading, but that is because of the suitable use case where it is in synch with these standards and not because it is custom created for this application.

    We do have a PLClite solution which can be used for lighting applications .

    The solutions are basically a modem of their own which have a UART interface for sending commands and data from ANY host .

    Only catch is that the solutions are as is and we don't look at any update or customization for these . This can be used as a reference.

    Regards .

    Hmm. According to that doc, the eval kit uses CENELEC-A, which is reserved exclusively for energy provider use. This suggests to me it not be a good approach for a home automation product.

    Hi Rick ,

    PLC-lite, is a low data-rate proprietary PLC implementation which uses CEN A . It is based on a memory reduced version of a BPSK-based PRIME-OFDM solution, but adds some of the robustness from what is found in the G3 protocol. 

    It is not designed for energy metering applications , but for any application which needs low data rates like home automation.

    Unless there is a stringent requirement to not be in CEN A space.

    Regards.
