Introduction




The Leak Gopher Z-Wave Valve Control (LGZW-1) works with Z-Wave enabled security alarm
systems to protect your home or business from water leaks. The Z-Wave Valve Control is designed to
connect to an existing alarm system where water sensors are attached. When the water sensors
detect water, the Z-Wave Controller can be programmed to tell the Leak Gopher to automatically turn
the water off, protecting your home or business. The Z-Wave Valve Control is Z-Wave Plus certified
to support the latest Z-Wave Controller capabilities.

You can also operate the electronic water valve directly using on and off buttons located in the top of
the Z-Wave Valve Control.


Z-Wave is a wireless mesh-networking protocol for reliable, intelligent home control of all Z-Wave
compatible devices. Z-Wave devices can act as repeaters to create a mesh-network to ensure
reliable communication regardless of the manufacturer or type of device. This product can be
included and operated in any Z-Wave network with other Z-Wave certified devices from any other
manufacturer. Z-Wave devices such as lamp modules, fan controllers, thermostats, dimmer switches
and many other types of home control devices are available from a wide range of manufacturers The
Z-Wave Alliance (
www.z-wavealliance.com
) provides a list of manufacturers of Z-Wave compliant
devices. Z-Wave was created by
Sigma Designs
and more details on the technology can be found at

How to install the Leak Gopher Electronic Water Valve



The plumbing in every building is different. Determining where to locate the Leak Gopher
Electronic Water Valve is an important part of the installation process. While outside the scope of
these instructions, the optimum place to locate the valve is where it can turn off all of the water
entering the premises to be protected. In a residential setting this is typically on the main water line
coming into the house. Variations in plumbing make it impossible to provide detailed installation
instructions for your installation. Your situation may require rerouting the water line, or other changes
to your plumbing. It is your responsibility to check with your local codes department to determine if a
licensed plumber is required to install the Electronic Water Valve.

You can get a 6 conductor 14 foot telephone wire and connector to extend the valve wire at
www.leakintel.com. You can also install a biscuit or other device to extend the wire but care should be
taken not to reverse the polarity on wires 2 & 5 and 1 & 6. Wires 2 & 5 open and aloes the valve.
Wires 1 & 6 report the valve position to the Leak Gopher.

Depending on your Z-Wave controller, and its capabilities, the Leak Gopher Z-Wave Valve Control
can be added to the controller as a Z-Wave device, operated directly from the controller, or
incorporated into scenes, etc.

Software Developer Technical Information
This section is intended for home control software developers to support LGZW in their home control
software. Users of LGZW do not need this information but it is provided here for serious DIYers who
want to understand how the device works under the hood.

All Z-Wave communication uses standard Z-Wave Command Classes. Each command class is fully
described in the Z-Wave specification documents available at
SigmaDesigns.com
. Specific details of
how each command class is used by the LGZW are described below.
Z-Wave Command Classes

BASIC
BASIC commands can also be used to turn the valve on or off and
report status
V1
NOTIFICATION_V4
Hardware failure of the valve is reported with a System Error
notification
V4
FIRMWARE_UPDATE_MD
Firmware in the LGZW can be updated via this class
V2

The Z-Wave command class version supported by the firmware in the LGZW can be obtained via the
VERSION_COMMAND_CLASS_GET command. Note that the firmware may support a later version
than is documented here.
Association and Association Group Info
The LGZW has a single Association Group, Group 1 also known as the “Lifeline” group as required
for Z-Wave Plus certification. Four (4) NodeIDs can be SET into Group 1. Typically the Z-Wave
system controller or Hub will be the most important member of Group 1.

When the ON or OFF buttons are pressed on the LGZW and the state of the valve changes, a
SWITCH_BINARY_REPORT is sent to each NodeID in Group 1. If a hardware failure is detected due
to a broken wire on the valve, a Notification Command Class is sent to each NodeID in Group 1.

10
LeakIntel.com
November 2017

Thus, it is critical that the Z-Wave system controller configure Association Group 1 with its NodeID
when the LGZW is joined to a Z-Wave network.

The Association Group Info command class can be used to obtain the name of group 1 “Lifeline” and
other information about the commands that can be received from LGZW.
Basic
The BASIC command class can be used to turn the valve ON or OFF. A BASIC_SET with a Value of
0 will turn the valve off (CLOSED) and value of 1-99 or 0xFF will turn the valve ON (OPEN).
Reserved values are ignored. A BASIC_GET will return a BASIC_REPORT with either 0x00
(CLOSED) or 0xFF(OPEN).
Binary Switch
The Binary Switch command class is identical to the Basic command class for the LGZW. A
SWITCH_BINARY_SET with a value of 0 will turn the valve off (CLOSED) and a value of 1-99 or
0xFF will open the valve. Reserved values are ignored. A SWITCH_BINARY_GET will return a
SWITCH_BINARY_REPORT with the current value of the valve (0x00 or 0xFF). Note that a
SWITCH_BINARY_REPORT will be sent if the valve is manually operated or fails to change to the
desired state. The valve takes several seconds to move to the opposite state. The REPORT is not
sent until the valve has stopped moving so there is some delay from the time you press the button
until the Z-Wave system controller receives the report.
Firmware Update
The LGZW firmware can be updated in the field using the Firmware Update Command Class. Contact
Leak Intelligence for the latest Intel Hex file of the Over-The-Air firmware for the LGZW. The Z-Wave
system controller must support the Firmware Update command class in order to update the firmware.
Refer to the Z-Wave system controller documentation to initiate a firmware update.

It is strongly recommended to bring LGZW within a few feet of the system controller. This ensures
reliable radio transfer of the firmware and minimizes the duration of the process. The firmware update
takes about five minutes of continuous radio traffic so the update should only be done when the rest
of the system is not required to be operational.

Notification
If a hardware failure is detected a NOTIFICATION_REPORT with a Notification Type of SYSTEM
(0x09) and an Event of 0x03 (Hardware Failure) will be sent to all nodeIDs in Association group 1.
The Z-Wave system controller should then inform the user that the valve is offline and needs to be
repaired. A NOTIFICATION_REPORT with an Event of 0x00 indicates the failure has been fixed and
the unit is operating normally. The NOTIFICATION_REPORT will be repeated once/hour until the
failure has been repaired. Note that the failure has to exist for 1 minute before the notification is sent.
If the failure is fixed, another NOTIFICATION_REPORT will be sent with an Event of 0x00 indicating

11
LeakIntel.com

the failure has been fixed. Unplugging the valve will send the notification report of 0x03 in 60
seconds. Plugging it back in will send the notification immediately.
