fasten the screw.
SWITCHING ON
2
Hold the magnet against the device (see
illustration below) for at least 1 second
while the water is running*.

more details
• The sensor starts to initialize and the
red light will ash (at least 5 seconds).
- If the sensor failed to initialize the red
light will stay on for 5 sec.
• The sensor will try to register to net-
work. Blinking green (at least 5 sec)
- If it failed to join, the red light will stay
on for 5 sec.
• The sensor calibrates - 4 liters are
needed for that. Green blinking will
change (indicating the number of detect-
ed pulses + 1)
- if calibration is successful, it will show
green for 5 sec
- if it fails within 10 minutes it will show

TROUBLESHOOTING
3
If the device did not register to the net-
work, it can be for 2 reasons:
• The device is not allowed in the net-
work and it must be registered with the
service provider.
The necessary data is on a separate
sticker in the package (DevEUI, AppEUI,
AppKey). Once the device is registered
repeat the switching on procedure de-
scribed under point 2.
• There is no LoRaWAN reception.
Contact your LoRaWAN service provider.
CHMASK SETUP (optional)
4
For AU915/US915 band devices only.
Follow the guide in step 1:
“Hold the magnet against the device for at least 1
second while the water is running.”
The ChMask is applied with holding the
magnet for dierent time.
• For default 64 channels setup: Follow
the guide normally.
• For pre selecting an 8 channel range,
keep holding the magnet for 5 seconds
(the light ashes red while holding).
After that the light will ash blue every 2
seconds, accompanied with red ashes
that ash as many times, as the blue
light has ashed. The blue light indicates
the channel range. After getting to the
desired range, the magnet needs to be
released after the blue light ash.
Channel ranges are as follows:
0-7 : blue has ashed 1 time
8-15 : blue has ash 2 times
16-23 : blue has ash 3 times
24-31 : blue has ash 4 times
32-39 : blue has ash 5 times
40-47 : blue has ash 6 times
48-55 : blue has ash 7 times
56-63 : blue has ash 8 times
