Time synchronization setup of the MeteoHelix Sigfox weather station

QUESTION: Is remote time synchronization possible with the MeteoHelix weather stations so that they can send data in 10 minute intervals on the hour?

ANSWER: MeteoHelix weather stations provide the ability to change settings and time synchronization remotely via a Sigfox down link connection. The below instructions and screenshots will guide you through the simple setup process.

Time Synch setup for Sigfox

Login to your Sigfox backend: backend.sigfox.com

  1. Click on Device Type in the horizontal menu.

  2. Navigate to the List in the left menu under Device Type: backend.sigfox.com/devicetype/list

  3. Under the Name column, select a device type as shown in the pictures.

  4. The left menu will change and select the menu item called Information.

  5. In the upper right click the Edit button as shown in the pictures.

  6. Next screen finally display the Downlink Data setup section where you will need to configure the following:

    1. For Downlink mode, select Direct.

    2. For Downlink data in hexa, enter the this text: 01{time}000000

  7. Click OK at the bottom of the page to save the changes.

1. Select your device type in the name column

2. click edit in the upper right of the device type information

3. Enter the downlink time data format in the downlink section

Simple tips to maximize your LoRaWAN and Sigfox weather station signal strength in the city

QUESTION: I don’t have good signal strength and get intermittent data from my IoT weather station in the city. What can I try to improve the wireless coverage?

ANSWER:

To solve wireless connectivity problems in urban areas, one must first know the following information:

  1. Where is the receiver located (gateway): Is it inside, outside, how many walls are between the gateway and the outdoors, on what floor and how high above ground level is it located.

  2. Where is the weather station located (end-node): Is it outside on a balcony or a lamp post, how many walls are between the gateway and the outdoors, how high above ground level is it located, and in general, what is between the weather station an the gateway.

Solutions for the city

  1. With many buildings around, the most common problem with wireless signal in urban weather stations is caused by building walls which weaken and block wireless signals from reaching the Sigfox and LoRaWAN receiver stations, also called gateways.

  2. Second most common problem is the gateway is location in the building. if located on the opposite side of a building, each wall and window between the gateway and the weather station weakens and potentially blocks the wireless signal. Try moving the gateway close to a window in the direction or your weather station and as high above the ground (on the highest floor of your building), outdoors or on the roof.

  3. Step 2 - Increase signal strength with a NANO/PICO/MICRO gateway or a signal repeater is also an option.

    1. Sigfox offers a micro-gateway and also a signal repeater station to increase wireless coverage between buildings.

    2. LoRaWAN offers many choices of gateways at varying price levels and performance. Searching the web for “LoRaWAN Gateways” will offer many choices.

    3. LoRaWAN gateway locations can be found on this TTNmapper map and the TTN Mapper phone app can help you find a location with good signal strength of LoRaWAN coverage.

Simple tips to maximize your LoRaWAN and Sigfox weather station signal strength in the country

QUESTION: I don’t have good signal strength and get intermittent data from my IoT weather station. I am in a rural area of the country. How can I improve my wireless coverage?

ANSWER:

To solve wireless connectivity problems, one must first know the following information:

  1. Where is the receiver located (gateway): Is it inside, outside, how many walls are between the gateway and the outdoors, and how high above ground level is it located.

  2. Where is the weather station located (end-node): Is it inside, outside, how many walls are between the gateway and the outdoors, and how high above ground level is it located.

Solutions for the country side

  1. In the country with wide open spaces, the single most common solution is to mount the weather station higher or on top of the closest hill to make sure it has line of sight view of the reciever which is called a gateway in IoT wireless systems like Sigfox and LoRaWAN.

  2. Second most common problem is that the gateway is located indoors or on the opposite side of a building where building walls weaken and block wireless signals from reaching their destination. Try moving the gateway close to a window, in your attic or outdoors or on the roof.

  3. Increasing signal strength with a NANO/PICO/MICRO gateway or a signal repeater is also an option.

    1. Sigfox now offers a micro-gateway along with a repeater station to get wireless coverage in a valley behind a hill from the Sigfox gateway.

    2. LoRaWAN offers more choices of gateways. Try searching the web for “LoRaWAN Gateway” and many choices will pop up.

    3. LoRaWAN gateway locations can be found on this TTNmapper map and the TTN Mapper phone app can help you find a location with good signal strength of LoRaWAN coverage.
