step 3; if it has already been joined, please skip step 3.
Step 3. Join the local LoRaWAN network: the magnetic triggering meter module initiates networking, the
LED light keeps on during the networking process, and the LED light will turn off when the
networking is successful.
Step 4. Report data: Magnetic trigger to report data, check whether the water meter parameters and flow
data are accurate through the cloud platform. If the data is deviated, it can be modified by setting
parameters.
Step 5. Parameter setting: After the meter module is assembled, use the production test tool provided by
HAC (if provided) or the cloud platform for parameter setting. To set the parameters using the cloud
platform, you must complete the meter module information installation on the cloud platform.
Step 6. The meter module goes offline: the meter module fails to report in two consecutive reporting cycles,
and the meter module goes offline. The next time the data is reported regularly, the network request
will be initiated automatically.
The hall element of metering module is as follow:

Precautions
6.1.
The magnet triggers the hall components of the meter module. The triggering time must be greater than 2S.
If the trigger time is less than 2S, there is a probability that the data report will fail.
6.2.
The magnetic trigger reporting function is invalid when the meter module is connected to the Internet (the
LED light of module is always on) or when the valve is controlled.
6.3.
The cloud platform cannot check the data reported by the magnetic trigger. The processing method is as
follows:
a) Observe whether the LED indicator status of the meter module meets the described in Chapter 4 when
the data is reported by the magnetic trigger.
b) Check whether the installation information of the cloud platform is consistent with the information of
the meter module.
c) Still unable to solve the data reporting problem, please contact our technical staff.
