  • Control sprinkler zones like any other X10 connected device
  • Multiple units can be networked for larger installations
  • Configure entire sprinkler program as a single X10 address, or assign X10 address to each sprinkler zone

Essential Info

Integrate sprinkler or watering system control into your X10 home automation system with the Rain8, a full-featured, 8-zone irrigation controller that accepts and reacts to standard X10 commands. This opens up the world of sprinkler and irrigation system control to anyone with X10 timers, remote controls, even over-the-Internet control using PC-based automation software.

Easy Setup
Setup is easy. All you have to do is momentarily connect the Rain8 to your PC's serial port to assign the X10 address and program cycle durations for each sprinkler zone. Once the X10 address and zone cycle durations have been set, the Rain8 can be disconnected from the PC and will respond to X10 signals just like any other X10-connected device (requires PowerLinc (#1132B) or TW523 (#1135) module, sold separately). You can also purchase the Rain8 Kit with PowerLinc included.

The Rain8 does not have to be connected to a PC for everyday operation.


What's Included

  • Rain8
  • Velcro® mounting strips

    Trigger Either of Two Distinct Programs
    Two distinct programs can be configured, each with its own address — a handy feature if you have different winter and summer watering needs, or night and day watering. For the ultimate in flexibility, you can even assign a unique device code to each sprinkler zone, and water only the zones you want for as long as you want.

    Installation Tips
    The Rain8 is designed for installation in a water-protected location or in a weatherproof enclosure. The sprinkler wiring termination block easily separates from the main Rain8 controller, allowing you to easily modify Rain8 programming without tedious rewiring. Multiple Rain8 modules can be networked together, requiring only one AC transformer and PLC interface.

    Order Together and Save
    To interact with your X10 system, you'll need an X10 interface, like the PowerLinc Module (#1132). And now you can get both products at once by ordering the Rain8 Sprinkler Controller & PowerLinc Kit (#3124C). For confirmation of your X10 signals, try the Rain8 2-Way X10 Sprinkler Controller (sold separately). If you're using a Mac, purchase the Rain8MB Sprinkler Controller for Mac instead.

    NOTE: When using #3124 with the PowerLinc module, a standard 4 conductor RJ-11 crossover phone cable is required (this cable is included with the #3124C bundle). When using #3124 with the TW523, use the straight-through cable packaged with #3124.

    Makes watering fun
    K McWhirter -- anaheim, CA   11/22/2004
    I use a HEYU2 with a custom Web/Perl interface I developed on Linux. I have can access any of the codes over the Internet, plus utilize timers. It works fantastic. No more dried out lawn and flowerbeds when I get home from Vacation. I can even use it along side of my webcams to chase stray cats from my flower gardens when I am not home. Awesome value and very functional.
    CARDIN A. -- seminole, FL   8/10/2004
    Working fine... Was able to update the hardware with downloaded software from the manufacturer to include running my well pump whenever a Zone was turned on... Great product!!!
    Ed -- st louis, MO   5/25/2004
    This product is great! I use 2 Rain8 devices and Homeseer to control my 12 zone irrigation system. I also can operate individual zones via my rf remote. I've looked at a number of options and found this to be the most effective and economical.
