INTRODUCTION
Your EVIE Sensor communicates to the WX8 to automatically disable your
watering schedules after 5mm of rain, reducing your water usage in the process.
The sensor uses two electrodes (A) connected
to a Radio Frequency (RF) Transmitter.
When water begins to fill the sensor, the circuit between the two electrodes
completes, and the RF Transmit ter can wirelessly communicate to the WX8
to stop watering. After the water in the sensor evaporates, the circuit is once
again disconnected, and the RF Transmitter tells the WX8 it can continue with
your watering schedules. The sensor holds a maximum of 25mm of rainfall.
Your EVIE Sensor regulates how quickly watering will resume
after rain. This comes from the amount of rainfall collected,
and how quickly it evaporates in heat or wind.

To communicate to the WX8IrrigationController, the
EVIE Sensor needs to be installed no more than 20 metres
from the controller with a clear line of sight

D
The EVIE Sensor needs to be mounted horizontally on a gutter
and attached with the wing nut screw (D) provided
Choose a gutter location where the EVIE Sensor will not be
knocked by surrounding trees or by potentially strong wind
Ensure the EVIE Sensor is with 50m range of your WX8
Use the elbow screw (E) to level the EVIE Sensor on your gutter
When water fills above the internal electrodes (A), the
EVIESensor will detect the moisture and any automatic
watering starts will be disabled in Holman Home
As the water evaporates and the water level drops below the centre weir(B),
the sensor will report back to your WX8 as dry, and any automatic watering
starts will be reinstated in Holman Home
PAIRING TO THE WX8 IRRIGATION CONTROLLER
Your EVIE Sensor should
already be paired with your
WX8Irrigation Controller
1. Check the DEVICE INFORMATION(C)
page in Holman Home to ensure
your EVIESensor is paired
to the WX8 correctly and the
battery is in good condition
2. If your EVIE Sensor does not appear
to be paired to your WX8, please see
our pairing instructions overleaf

CHECKING YOUR EVIE SENSOR
To check if your EVIE Sensor is
working, please follow these steps:
1. Fill the sensor with water
2. Stand at ground level, holding the
sensor under your gutter near the
intended installation point
3. You will need to wait up to a minute
for HolmanHome to detect moisture
through the EVIE Sensor
4. HolmanHome should currently
report ( F) that the EVIE Sensor
is detecting and that automatic
watering starts have been disabled
5. Once HolmanHome has confirmed it is
working correctly, empty the water and
install the sensor in the desired location

TROUBLESHOOTING
If for some reason the EVIE Sensor has been disconnected from your WX8 ,
Holman Home will show this in the DEVICE INFORMATION screen (F ).
The following instructions highlight how to re-pair your EVIE Sensor to the WX8:
1. Bring your EVIE Sensor to your WX8 irrigation controller so
that you can operate both devices simultaneously
2. On the EVIE Sensor, remove the rubber plug (G) on the underside
and check there are two CR2032 batteries (H) installed
3. On your WX8, turn the dial to OFF
4. Press and hold S TAR T for 5 seconds until the LEDs of ZONE 1 and 2
both flash, alternating between red and blue (for 20 seconds only)
The next step must be completed in the first 20
seconds while the LEDs are still flashing
If you run out of time it is possible to attempt the process again
5. On the EVIE Sensor, press and hold the internal button(I)
until the WX8 LEDs of ZONE 3 and 4 are alight
If the pairing succeeds, these LEDs will be blue
If the pairing fails, these LEDs will be red
6. After pairing is successful, on the WX8 , turn the
dial to RUN to exit the pairing mode
7. Wait at least one minute for the Holman Home to show EVIE Sensor
is connected to the WX8 in the DEVICE INFORMATION screen (J)
8. Replace the rubber plug back into EVIE Sensor (G)
9. Follow the instructions for CHECKING YOUR EVIE SENSOR as listed overleaf
10. Re-install your EVIE Sensor as per the INSTA LL AT IO N instructions overleaf
