What is Z-Wave?

Z-Wave is the international wireless protocol for communication in the Smart Home. This device is suited for use in the region mentioned in the Quickstart section.

Z-Wave ensures a reliable communication by reconfirming every message (two-way communication) and every mains powered node can act as a repeater for other nodes (meshed network) in case the receiver is not in direct wireless range of the transmitter.

This device and every other certified Z-Wave device can be used together with any other certified Z-Wave device regardless of brand and origin as long as both are suited for the same frequency range.

If a device supports secure communication it will communicate with other devices secure as long as this device provides the same or a higher level of security. Otherwise it will automatically turn into a lower level of security to maintain backward compatibility.

Product Description

This device measures the rain level on a certain position. The device is IP55 rated and can be used outside the home in the garden or on any other place exposed to rain. The device has a funnel on the top-side that will collect the rain on a certain diameter. The internal mechanics and electronics counts the rain level and will report it every about 4 minutes if and only if there is rain.  The device also monitors a heavy rain condition (10 l/sqm within 5 minutes) and will send out alarm messages when detected.
A request from the controller will be answered depending on the wake-up interval delayed by the Z-Rain.

Prepare for Installation / Reset

Please read the user manual before installing the product.

In order to include (add) a Z-Wave device to a network it must be in factory default state. Please make sure to reset the device into factory default. You can do this by performing an Exclusion operation as described below in the manual. Every Z-Wave controller is able to perform this operation however it is recommended to use the primary controller of the previous network to make sure the very device is excluded properly from this network.

Reset to factory default

This device also allows to be reset without any involvement of a Z-Wave controller. This procedure should only be used when the primary controller is inoperable.

Push the button inside the device for at least 10 seconds

Safety Warning for Batteries

The product contains batteries. Please remove the batteries when the device is not used. Do not mix batteries of different charging level or different brands.


The device consists of three pieces. The base (1) contains the gauge and a indicator to place it on a flat surface. The electronics block (2) is snapped into the base and a hood (3) covers the case and provides the funnel to collect the rain. Simple close-wise turning mounts and unmounts the hood. Before using the device the batteries need to be inserted into the electronics block. For this the device needs to be opened and the electronics block removed. Once the battery is installed the electronics block need to be placed into the base:

1. The flat side of the electronics block needs to be towards the gauge.
2. You need to push the two snap-in noses from the electronics block away to keep the block tight to the base and to avoid any water leckage.

The base can now be placed on a flat surface. If the surface is not flat -  e.g. on soil? the device still must stand even to ensure correct measurement of the rain.

Note: Before the unit is ready for use, please remove the transport lock (small white cushions under the rocker)


On factory default the device does not belong to any Z-Wave network. The device needs to be added to an existing wireless network to communicate with the devices of this network. This process is called Inclusion.

Devices can also be removed from a network. This process is called Exclusion. Both processes are initiated by the primary controller of the Z-Wave network. This controller is turned into exclusion respective inclusion mode. Inclusion and Exclusion is then performed doing a special manual action right on the device.


1. Open the hopper
2. Remove the transport lock
3. Open the battery compartment and insert the batteries.
4. Press the button once with a paper clip.


1. Open the hopper.
2. Open the battery compartment.
3. Press the button once with a paper clip.

Product Usage

Once the device is included and placed on the right spot it will report the rain level and alert on heavy rain. The max. precision of the rain meter is 3,5 mm rain per hour. Please not that the first measurement result right after start of rain may be inaccurate due to the measurement principle. The device counts full buckets of water and the filling level of the bucket prior to the start of rain is undetermined.

Depending on the environment the device may get dirty over time. Please check the interior of the device frequency to remove old leafs and dirt that may cause incorrect measurements.

Node Information Frame

The Node Information Frame (NIF) is the business card of a Z-Wave device. It contains information about the device type and the technical capabilities. The inclusion and exclusion of the device is confirmed by sending out a Node Information Frame. Beside this it may be needed for certain network operations to send out a Node Information Frame. To issue a NIF execute the following action: Push the Z-Wave button once

Communication to a Sleeping device (Wakeup)

This device is battery operated and turned into deep sleep state most of the time to save battery life time. Communication with the device is limited. In order to communicate with the device, a static controller C is needed in the network. This controller will maintain a mailbox for the battery operated devices and store commands that can not be received during deep sleep state. Without such a controller, communication may become impossible and/or the battery life time is significantly decreased.

This device will wakeup regularly and announce the wakeup state by sending out a so called Wakeup Notification. The controller can then empty the mailbox. Therefore, the device needs to be configured with the desired wakeup interval and the node ID of the controller. If the device was included by a static controller this controller will usually perform all necessary configurations. The wakeup interval is a tradeoff between maximal battery life time and the desired responses of the device. To wakeup the device please perform the following action: Push the Z-Wave button once

Quick trouble shooting

Here are a few hints for network installation if things dont work as expected.

  1. Make sure a device is in factory reset state before including. In doubt exclude before include.
  2. If inclusion still fails, check if both devices use the same frequency.
  3. Remove all dead devices from associations. Otherwise you will see severe delays.
  4. Never use sleeping battery devices without a central controller.
  5. Dont poll FLIRS devices.
  6. Make sure to have enough mains powered device to benefit from the meshing

Firmware-Update over the Air

This device is capable of receiving a new firmware 'over the air'. The update function needs to be supported by the central controller. Once the controller starts the update process, perform the following action to confirm the firmware update: Push the Z-Wave button twice

Association - one device controls an other device

Z-Wave devices control other Z-Wave devices. The relationship between one device controlling another device is called association. In order to control a different device, the controlling device needs to maintain a list of devices that will receive controlling commands. These lists are called association groups and they are always related to certain events (e.g. button pressed, sensor triggers, ...). In case the event happens all devices stored in the respective association group will receive the same wireless command wireless command, typically a 'Basic Set' Command.

Association Groups:

Group Number Maximum Nodes Description
1 5 Lifeline
2 5 Switching Command when Rain (> 0 mm/h). Basic Set Command is sent.
3 5 Heavy Rain detected. Basic Set Command is sent.

Configuration Parameters

Z-Wave products are supposed to work out of the box after inclusion, however certain configuration can adapt the function better to user needs or unlock further enhanced features.

IMPORTANT: Controllers may only allow configuring signed values. In order to set values in the range 128...255 the value sent in the application shall be the desired value minus 256. For example: To set a parameter to 200 it may be needed to set a value of 200 minus 256 = minus 56. In case of a two byte value the same logic applies: Values greater than 32768 may needed to be given as negative values too.
