2.2 Installation

2.2.1 Assembly of the weather station

Setup the weather station following DAVIS INSTRUMENTS Instructions:

  • Sensor suite 6322CM or 6820CM
  • Solar box 6612 (only for pole fixing)
  • Cabled Weather Envoy®6316CEU6316CEU
  • WeatherLink® Serial-Port Data Logger 6510SER 6510SER
  • Tripod (if present) 7716A
  • Pole kit (if present) 7717
  • UV sensor (if present) 6490

Important notes (not exhaustive - please refer to Davis documents for full notes):

  • enginko LoRaWAN® interface (MCF-LW06DAV or MCF-LW06DAVP) must be the last device to be powered on.
  • 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.
  • Check the battery voltage before installing the weather station in the final place. If less than 6.3V recharge it.

2.2.2 LoRaWAN interface

On the DW-6612 solar panel box proceed as follow (see below image):

2.3 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 applicarions 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 :

2.5 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.

3. Setup

3.1 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.

3.2 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.

3.3 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 01) 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.

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.

4. Diagnostic

Press Check to verify the correct communication betweet the LoRaWAN® interface and the Davis envoy.

5 LoRaWAN network

The sensor is compliant with LoRaWAN® specification 1.0.2, regional 1.0.2b.

5.1 Activation

The device supports the following activations on a LoRaWAN® network:

  1. NONE: sensor not activated
  2. OTAA: the JoinEUI and the AppKey not setted, must be written to the device;
  3. OTAA MCF88: Over the air activation, fixed keys: JoinEUI = 904e915000000002, AppKey on request;
  4. OTAA ENGINKO: Over the air activation, fixed keys: JoinEUI = 904e915000000002, AppKey on request;
  5. ABP: requires writing to the device of NwkSkey, AppSkey, DevAddr.

The device exits factory activated with NONE mode. On request devices can be shipped aleady activated.

Note: in OTAA AppKey is write only, in reading the field will always be empty, even if set.

5.2 Other settings

Network settings:
please keep “Any” settings. Change it only if Objenious network is used (default_ any).

Network type:
LoRa syncword 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 accodingly to country requirements.

6 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 setted, 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).

7 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.

7.1 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, DevAddress, 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 from this one.

These configuration can be done in the 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.
