Overview of the system Wittra’s sensor tags, mesh-routers and gateway together form a mesh network based on 6LoWPAN (IPv6 over Low-Power Wireless Personal Area Networks). The network is IP-enabled down to the sensor tags, where data is communicated wirelessly over IEEE 802.15.4g radios in the Sub-GHz RF band. The data can easily be accessed via our Wittra portal by adding an integration; For further information please have a look at Accessing your data.
tag does not need to be turned on all the time which decreases power consumption and - as a consequence - increases operational lifetime. A mesh-router - in contrast - has the main purpose of forwarding data packets. This is the reason why it needs to be powered all the time. A border-router sits inside a gateway. It is the end destination of data packets in a mesh network. The border-router conveys the data to the gateway which then sends the data up securely, via HTTPS, to our Wittra portal.
Expected range The radio in the sensor tag, mesh-router and border-router runs Sub-GHz in the industrial, scientific and medical (ISM) frequency band. By communicating in this frequency domain you have a better range than for example the higher frequency band of 2.4 GHz. You also have a better penetration meaning you can communicate in harsher radio environments such as construction sites and in cities, where line of sight is not an option.
summarized below: Spoofing is mitigated using an authentication process utilizing JWTs that are signed by a private key stored in a TPM on the gateway which are checked in registered devices on our cloud service, where the respective public key is stored. Tampering is mitigated using DTLS/TLS to encrypt the data sent between sensor tag and gateway, and between gateway and Wittra portal.

Devices This view provides a list of devices that are added to your project. You can filter them based on the types of devices by clicking on the checkboxes next to device IDs or device names. Firmware For each device, there is a field indicating which firmware version it is running. The firmware version could be highlighted in one of the following colors. Green: Device firmware is up-to-date with the system version for the project, and the system version is the most recent version.
The gateway, sensor tags and mesh-routers regularly indicate their presence in the network. In the Project Dashboard project view, the time when a device last reported can be seen in the Last Seen column. If the device report interval is within normal limits the device is marked with a green indicator. If a device is disconnected or has le the network, the indicator will turn gray. Under the Last Boot column, the device reports the last time it re-started.

To distinguish between mesh-routers and sensor tags, remove the cradle the devices sit in. On the back of each device there is a model number. Mesh-routers are marked with model number MESHROUTER-1.
Charging the sensor tags 1. Collect all sensor tags. Initially you need to charge them because they are shipped with low charged batteries. 2. Unmount the protection cover with your hands or by using the accompanying tag tool from the box according to the pictures below. Place the tag tool in front of the tag and push towards the tag and then push up. The protection cover will be released. 3. Connect the Power Supply Unit 5V according to the picture. The Power Supply Unit 5V is included in the box. 4.
Set up your gateway The gateway allows your IoT Solution to connect to the Wittra portal. Mount the antenna Start by mounting the antenna on top of the gateway. The antenna is included in the box. Open your gateway Press the two metal clips on the bottom of the casing as in shown in picture below.
To assemble the gateway casing once again, please not that the side parts are non symetrical and need to be mounted on the correct side.
Setup an Internet connection Plug in an Ethernet network cable in the Gateway according to the picture and connect the other end of the cable to your router or switch. When the cable is connected, continue with the Power the Wittra Gateway step. NOTE: The Ethernet cable is not included in your IoT Solution. Power the Wittra Gateway 1. Connect the 12V Power Supply according to the picture. The 12V Power Supply is included in the box.
2. Wait 3 minutes for the Gateway to boot and start. This Table depicts the Raspberry Pi's two LED indicators: LED Color Blink pattern Status Red LED Steady on The Gateway is powered. Green LED Steady o The Gateway is not connected to any network. (There might be a link-local connection, but no IP address has been acquired) Green LED 1 short blink and then 1 second o The Gateway has connected to the local network but has not yet verified that there is Internet access.
You are now ready to register your IoT Solution in the Wittra portal. Go to the portal and follow the instructions to finish setting up your IoT Solution. You should perform the following steps in the portal: 1. Setup an organization. 2. Activate a subscription. 3. Setup a project. 4. Register the devices. You will need to enter your batch token to register your devices.
Updating your system Wittra regularly releases improved so ware for all your devices. This page describes the various parts included in updating your devices to the latest releases. There are two ways to update your Wittra devices (i.e. tags and mesh-routers): Manual Automatic Manual update is required for: First time use PAN ID change Security update (e.g. DTLS key update) An automatic update can take up to 24h.
Manual update The manual update method is the faster one, but is limited in range and requires manual intervention (reboot the device in manual update mode). To update your sensor tags and mesh-routers manually, you will have to collect the devices you wish to update and place them close to the gateway. Set the sensor tags and mesh-routers in manual update mode by using the included magnet and OTG adapter from the box. Step 1.
Manual firmware update will take approximately 2 minutes per device. Automatic update If you do not take any further action, nodes will be automatically upgraded over 6LoWPAN. There is no need to gather the devices nor reboot them into manual update mode. Note that this procedure is significantly slower, and could take between several hours and up to a day (due to lower bandwidth and spectrum regulations).
Step 2. Restart each mesh-router in place by inserting the provided OTG adapter. NOTE: Restart each mesh-router a er you put everything in place. Also make sure not to put any other mesh-router in close proximity to the one you are restarting. This is because the mesh-router you are restarting might erroneously choose the other mesh-router as its parent, which would result in an ine icient network topology. Step 3. Check the link quality status under NETWORK TREE view in web-portal.
Tags within your network can now start sending data. Check out Accessing your data Updating security settings We use a secure-by-design approach where we incorporate security from the early architecture design stage and throughout the evolution of the products. Read more about security measures employed in Secure system. It's good practice to update security settings from time to time.
8. Continue with Power the Wittra Gateway. 9. Collect all your devices and do a manual update. Follow the steps in Manual update NOTE: You will need to manually update all the devices in the network for this change to take e ect. Accessing your data When your devices are registered and updated they are ready to deliver data. This document describes the di erent ways you can monitor and make use of the Wittra IoT solution.
The publish_time or publishTime fields contains timestamps of when the message was sent. Example of a JSON payload: json { "message": { "attributes": { "deviceId": "D0123456789ABCDEF", "gatewayId": "G0123456789ABCDEFEE", "version": "v1" }, "data": "eyJiYXR0ZXJ5Ij...", "messageId": "1000000000000000", "message_id": "1000000000000000", "publishTime": "2020-01-01T01:01:01.001Z", "publish_time": "2020-01-01T01:01:01.
Example sensor data: json { "battery": 3.876, "accelerometer": { "x": -0.079, "y": 0.004, "z": 1.016 }, "gyroscope": { "x": -0.317, "y": 0.296, "z": 0.479 }, "temperature": 25.943, "usage": { "moving": 0, "stationary": 301 }, "magnetometer": { "x": 0.367, "y": 0.196, "z": 0.802 }, "neighbours": [ { "id": "DFEDCBA9876543210", "rssi": -54 }, { "id": "D0123012301230123", "rssi": -55 } ], "timestamp": "2020-01-01T01:01:00.
For example, if the tag is lying like the picture shown above, the accelerometer should report a Z value of ~1 g, due to the floor pushing up on the tag with a force matching the gravitational pull to the center of the earth. If the tag is spinning on a turn table with a speed of one full revolution per second in a counter clockwise direction, the gyro should report a Z value of ~360 °/s. Positioning your devices This guide will help you set up the system for positioning.
Step 2. Choose the Position devices in the menu to the right and click on each mesh-router to have them appear on the map. When the mesh-routers have appeared on the map, drag them to their true location. To ensure higher accuracy, it is recommended to use a drawing (e.g. a floor plan of the site) as an overlay. Learn more about overlays in the Map layers section. NOTE: All mesh-routers need to be placed on the map for the positioning algorithm to work.
Devices You configure your devices by pressing the Details button under the Devices tab. Gateway The gateway serves as a proxy for the data, passing it on from the network up to cloud. It is not a configurable device in the same sense as a mesh-router and a tag. What you can configure is a Name for your gateway for easier identification, as well as a Group. A group can be used when filtering devices on the map in Visualization tab.
There are two ways of setting a posting interval for a tag: Interval-based data and Event-based data posting. Event-based data is only applicable for Battery, Temperature, Network, and Usage (Moving/Stationary). Under Settings for each sensor, you can activate Interval-based data and/or Event-based data posting. For interval-based data you set the posting interval for all sensors by using the slider under Sensor data posting interval.
Network settings Here you can set a PAN-ID for your network, if you want to connect two networks e.g. on two di erent sites. To setup roaming between two sites, they both neeed to have the same PAN-ID. Roaming You can enable roaming between two or more networks. Note that these networks should not be within range of eachother. To enable roaming, follow these steps: 1. Copy the security.txt file from gateway B and replace the security.txt file in gateway A with this copy. 2.
Troubleshooting Have an issue? Look here for support. General Unboxing and Getting Started My IoT Out of the Box is not working 1. Look through this page to see if a more specific question matches the issue you have experienced. 2. See My Gateway is not working. 3. Ensure that all hardware looks intact. If not, please contact the supplier. Can I set up my sensor network outdoors? In short, yes. However, there are two main considerations for this: 1. It is only the sensor tag that is weatherproof.
My IoT Out of the Box is missing parts Please contact the supplier from whom you purchased the "IOT OUT OF THE BOX". How many sensor tags and mesh-routers can I connect to the network Your subscription will state the number of devices you can connect to your network. The maximum number of mesh-routers are depending on the number of sensor tags and tra ic in your network. Please contact Wittra Customer Support for further information and network dimensioning.
Please contact your supplier from whom you purchased the sensor tag. I have lost my release key/tag tool for the USB connector cover protection Please contact your Wittra hardware supplier for additional sales. Gateway Unboxing and Getting Started How do I install a new Gateway? Please have a look at the Set-up your Wittra Gateway section in the Getting started guide. I can’t open my Gateway The Gateway is opened by pushing the two side locks upwards.
please see section My gateway is not working. My Gateway is not working If you have a gateway that is not visible on the portal go to part 1, otherwise go directly to part 2. Part 1. Gateway is o line in portal Please start by opening the gateway casing and check that the power LED on the Raspberry Pi shows a steady red and that the motherboard's (the board on which the border router is mounted) LED shows a steady green.
Part 2. Gateway is online in portal but is not working correctly If the Gateway is online on the Wittra portal it means it has been set up correctly to the Internet. First try and restart your gateway to see if the error disappears. If that is not the case, please try and update the gateway on the Wittra portal. If the gateway still is not working, try to perform the update procedure again.
Do I need to protect my mesh-router in heavy rain? The mesh-router should not be exposed to heavy rain. If you are mounting your mesh-router outdoors, please set it up under some sort of rain cover, e.g. under the eaves of a building. Upgrade and Updates A er an update of the mesh-router, the mesh-router is not working Please allow some time to pass a er an update to allow the mesh-router to come back online. It might be the case that other devices in the mesh network have not finished updating yet.
When charging, your sensor tag will blink slowly. The LED will be on for three seconds, then o for three seconds, and so on. Once the battery is full, the LED will stop blinking in this pattern. I need to reset my tag Use the OTG adapter included in the kit to plug into the micro USB connector at the top of the device, you should see two quick blinks which indicate that the device has rebooted and the OTG adapter can be unplugged.
General Where do I set my Webhook address? Please look at Register an integration for information on how to register a Webhook. The Webhook is not working Make sure that the Webhook server is reachable from the internet, i.e. that no firewall blocks incoming TCP tra ic on the port used by the server. Take a look at our examples on how to set up a test Webhook server. What is the format of the streamed sensor data? Please look at Data payload for more information regarding the payload in the data stream.
