Free run time software for scheduling your irrigation!
-details at bottom of page-

The Rain8net is a modular 8-zone sprinkler controller module that can be controlled over the Internet by any computer or other control device. It is capable of driving standard 24VAC irrigation valves directly.


Additional modules may be daisy chained to provide control and 24 VAC power to as many as 2040 irrigation zones from a single COM or USB port.
  • Turn on or off each of the zone individually
  • Turn off all zones on a specific module
  • Turn off all zones on all modules
  • Get the current status of all zones
  • Default run timer for each zone to prevent over watering
  • Up to 1000' between Rain8 and computer


The Rain8net requires a computer (or other automation device) running to control all scheduled irrigation.
Three modules, 24 zones,
in mounting rack.


Product Announcement
Need a dry contact relay version?More info...

There is a single connection between the controlling device and the "master" Rain8. This link itself may be:
  • Hardwired
    The distance between the computer and the controller is up to 1000' and requires only 3 wires: TX, RX and GND. Cat5 or 2 twisted pair phone cable okay.
  • Eithernet/WIFI More info...
    The distance depends on the actual equipment used.
  • RF Modem More info...
    Great for distances over 1 mile between Rain8 and computer.
The 24VAC power and network communications are transferred from master to slave-to-slave etc.

The network connection for the slave units is an 8 conductor RJ45. Each slave has a pair of these modular jacks to pass on data and power to the next one in a daisy chain. Each slave also has a RS232 connection that is used only to assign the address during the initial configuration.

Software Based Control Options

These solutions require a PC running at all times irrigation is scheduled.

Hardware base Control Options

Here the Rain8net does not connect to a computer but to a general purpose home automation system.
