Installation Instructions
Assembly of the Weather Station
Setup the weather station following DAVIS INSTRUMENTS Instructions:
- Sensor suite or Solarbox (only for pole fixing)
- Tripod (if present)
- Pole kit (if present)
- UV sensor (if present)
Important notes (not exhaustive -please refer to Davis documents for full notes): On the rain collector, remove the plastic tie that holds the tipping spoon in place during shipping. Install the sensor suite (UV sensor, solar radiation sensor, rain collector) as level as possible to ensure accurate measurements. In the Northern Hemisphere, the solar panel should face south for maximum sun exposure, and the anemometer arm should point north for proper wind direction calibration. In the Southern Hemisphere, the solar panel should face north for maximum sun exposure.
LoRaWAN Interface
On the DW-6612 solar panel box proceed as follow:
- Remove the 6316CEU by sliding down-up and pull.
Antenna
Mount the antenna on the pole using fasteners. On the DW-6612 solar panel
box, connect the antenna connector to the MCF-LW06DAV device (Davis station to
LoRaWANTM interface) as shown below D by entering the box using the gasket on
the bottom side’s hole:
PM Sensor
Mount the solar shield with the PM sensor on the pole (at the back of the
DW-6612 solar panel box) following the enclosed instruction.

Configuration
To deploy the sensor, use LoRaWEB online tool, to setup LoRaWAN® credentials
and other preferences (only available for Windows®) :
LoRaWEB TOOL (iot.mcf88.cloud/LoRaWeb)
Before connect the device the first time, please install LoRaBridge
applications and drivers:
https://iot.mcf88.cloud/LoRaWeb/#/download
Validate your settings reading data after the write.
enginko provides, upon free registration, user manuals, javascript examples,
downlink generator, uplink decoder, firmware updates and different tools :
System led
Firmware update
Save the new firmware file (.exe) on the PC, run the file, select the USB
FW port and start the update:
and waiting for the end message.
Setup
Period
Period is the interval (in minutes) between one measure and the next one. The
sensor sends one measures for every transmission. Value can be between 15 and
65535 minutes (default: 30 minutes).
Period interval can be set with App or with downlink command.
Altitude compensation
When the sensor is not installed at the sea level, the reading of barometric
pressures at other elevations must be compensated.
Set the right altitude value with LoRaWEB.
Value can be from -300 to 3000 meters.
Altitude can also be set with downlink command.
Other settings
-
DST:
set to change DST (default: none). -
Time sync uplink:
set to disable time synchronization request (default: enabled).
Normally sensor asks for a time sync at every power on (uplink starting with
- or once a week. If no or wrong reply received it will retry after 1 week. If not handled in the right way can cause a unnecessary battery consumption (battery life < 2 years).
Please check chapter 2.1 of “DATA FRAME FORMAT” document
-
Confirmed Uplinks:
set for unconfirmed uplinks (default: confirmed uplink). -
Single join/day:
set for to allow only one join per day (default: multiple join allowed). -
LED working:
Set OFF to turn off the diagnostic led. -
USB:
Internal use.
Diagnostic
Press Check to verify the correct communication between the LoRaWAN® interface and the Davis envoy.
LoRaWAN network
The sensor is compliant with LoRaWAN® specification 1.0.2, regional 1.0.2b.
Activation
The device supports the following activations on a LoRaWAN® network:
- NONE: sensor not activated
- OTAA: the JoinEUI and the AppKey not setted, must be written to the device;
- OTAA MCF88: Over the air activation, fixed keys: JoinEUI = 904e915000000002, AppKey on request;
- OTAA ENGINKO: Over the air activation, fixed keys: JoinEUI = 904e915000000002, AppKey on request;
- ABP: requires writing to the device of NwkSkey, AppSkey, DevAddr.
The device exits factory activated with NONE mode. On request devices can be
shipped already activated.
Note: in OTAA AppKey is write only, in reading the field will always be
empty, even if set.
Other settings
-
Network settings:
please keep “Any” settings. Change it only if Objetions network is used (default_ any). -
Network type:
LoRa sync word can be setted as “private”(0x12) instead “public” (0x34), but the NS must be setted accordingly(default: public). -
Band:
select the right LoRaWAN ® band settings accordingly to country requirements.
Passwords
The device can be protected by passwords, to avoid unauthorized persons to read data or modify parameters. As default passwords are equal to 0.
Allowed values range from 0 to 999999999 (only numbers).
To change the passwords, set the new values with LoRaWEB:
Once the passwords are settled, to gain access from LoRaWEB to the sensor, et
the right values before reading from the device:
To bring back the sensor to factory default and reset the passwords, a reset code must be requested to enginko (please provide the DevEUI of the sensor when you ask for that code).
Configuration file
With LoRaWEB is possible to configure the device using an XML file, instead to
manually adjust the parameters (for details about the file format please ask
to enginko). This is very useful especially in case of multiple devices
configuration.
With “Save” button an XML file with the actual configuration of the sensor
will be generated. This is useful to store or clone the configuration, or to
send it to enginko’s support if needed.
Multi devices configuration
With LoRaWEB is possible to configure many devices in an easy way.
For multi-configuration is needed at least one XML file with the parameters to
set.
Settings on this file will be applied to all the sensors.
With an additional XLS file is possible to load different LoRa configuration
parameters (Activation Type, AppKey, AppEUI, NetKey, Dev Address, Band,
Private option) for each sensor, based on DevEUI.
XLS is prevailing on the XML, so if both files are enabled, if the DevEUI of
the device matches one of the DevEUIs in the XLS file, LoRa parameters will be
setted.
These configuration can be done in the Settings:
- Use of the general configuration by file; Use of the specific configuration by file.
For details on files format please ask to enginko.
