X10 is a communications "language" that allows compatible products to talk to each other via the existing 110V electrical wiring in the home. No rewiring is necessary. Up to 256 different addresses are available. If you want more than one device to respond to the same signal, simply set them to the same addresses. All X10 compatible products can be freely mixed and matched - Use Leviton together with X10 [L1 ], Stanley, etc.

There are 3 basic types of devices:

  • Transmitter
  • Receiver
  • Transmitter/Receiver Combo

Why is there a page related to X10 on the Tcl Wiki?

MPJ Because most computer control of X10 devices are done with serial communication and Tcl is a great language for serial port communication. There are also RF devices that are used to interface with X10 devices.

I have created a pure Tcl X10/CM11 library at Tcl X10 Library it doesn't need any compiled extensions and should work with any Tcl 8.4 or up (because of the serial port stuff used, 8.4 is required). I think it is simple to use, but there is no GUI yet. Just a library that can handle X10 events, supports aliasses and, of course, lets you send commands to your X10 devices.

Wiki Examples


  • X10-CM17A[L2 ] A Serial Port connector that transmits an RF signal to a RF/X10 convertor


  • X10-UR47A[L3 ] A 6-in-1 Universal Remote that also has a ability to sent RF signals (310 MHz) to other X10 RF Receivers (using the AUX button)


  • X10-mr26a[L4 ] A Serial port device that can receive RF signals (310 MHz).
  • V572[L5 ] An alternative to X10's RR501 and TM751 transceivers.
  • W800[L6 ] An alternative to X10's MR26A that can also handle security devices.

DKF: X10 is also the previous protocol version of X to the current X11. It's mainly of historical interest though.

AMG: KOMPRESSOR [L7 ] exhorts us to destroy X10 [L8 ] [L9 ] because "popping up window is computer assault". All must join to destroy ads. (MM VOCAL, CRUSH, FEAR, SYNTHESIZER, POWER... AK... is that you?)
