After reading this article, you’ll be able to:

  • Prepare your environment to start using FEMTO Light Indoor Gateway

  • Configure a FEMTO Light Indoor Gateway

What is FEMTO Light Indoor Gateway?

FEMTO Light Indoor Gateway is a LoRa gateway that can be used for any Spacewell LoRa device to connect to the Workplace Platform.

CONNECTION IMAGE

image of the gateway

FEMTO Light Indoor Gateway connects to an existing (guest) Wifi, a seperate wifi network, or to ethernet.

When using WiFi: Since the data between the sensors and the hub is communicated over LoRa network, we assume the impact of this device on the WiFi network will be max 250MB/hub/month.

Hardware & Network Requirements

Mini hubs run on 2.4GHz

See below table for information on which ports to open, if they should be open for in- and/or outbound traffic etc.

 Network Traffic - Whitelisting URLs & Ports

We sync all our hubs to the same open NTP (network time protocol) servers so we have consistent timings in our data warehouse.

How to use below table

  • as mentioned above, ideally just the ports mentioned should be opened

We recommend not to use specific IP addresses or DNS destinations in the firewall as they can and probably will change in the future!

  • protocol information and AL descriptions are extra

Depending on the environment main location, Spacewell Workplace tenants are created in an EU- or US-environment. Hence, for some ports to be opened, the destination address might be a different one:

  • eu: spacewell.eu1.cloud.thethings.industries

  • usa: spacewell.nam1.cloud.thethings.industries

How to Activate the Hub

Configuration needs to be done on a computer.

Make sure to run through the config settings fairly quickly, else connection will time-out.

Step 1: Device connection

  1. plug in the device to power

  2. the device will turn up in your wifi list on your computer

  3. connect to the ifemto wifi; use the pw that is mentioned on the back of the device

  4. connect in the browser to IP 192.168.4.1

  • Screenshot of “web services: connected” in the top right corner

Step 2. “set LoRa” LoRa Setting:

  • Gateway ID will be visible

  • LoRa Packet Forwarder

  • Server address: TTN

  • Radio Frequencies (different for EU, US etc)

  • Save button

  • After Success message: Go back to the main config page

Step 3. Select EITHER Ethernet OR wifi

  •  Select “WAN”

    • In Ethernet Settings, select DHCP

    • Save button

    • the device will reboot (page will look as if it’s stuck = “web service” (in the top right corner) = disconnected)

    • LED on device: power = on/orange; Ethernet LED blue; LoRa LED blue

    • Select “Wi-Fi” (make sure to remove any LAN cable; only power supply should be plugged in)

      • All possible networks are visible on the config screen

      • Select the network you want to connect to and provide the password

      • Save button

      • the device will reboot (page will look as if it’s stuck = “web service” (in the top right corner) = disconnected)

      • power = on/orange; wifi LED blue; LoRa LED blue

If your configuration was successful:

  • the device will no longer show up in the WiFi scanning list of your computer

  • If your configuration was successful (power = on/orange; wifi LED blue; LoRa LED blue) the gateway is connected to the LoRaWAN network and is ready to handle packets. Your Spacewell Implementation Consultant can confirm if the gateway is connecting to the Workplace platform (see /wiki/spaces/KB/pages/492072 ).

Additional Information

Operating Modes

  1. Configuration Mode (CONF)

    1. In this mode, the device acts as a WiFi AP to which users can connect and configure a WiFi
      network(s) to which the gateway will connect to during normal operation. The device cannot
      route LoRaWAN packets in this mode.

  2. Gateway Mode (GW)

    1. In this mode, the device acts as a gateway to route traffic between the LoRaWAN Device
      and the Network. The WiFi AP for configuration is not available in this mode.

LED States

Button Actions

There are three possible button actions on the the Tabs Mini Hub

  1. SETUP Button pressed for 10s:

    1. Switch to CONF mode if in GW mode.

  2. SETUP Button pressed for 5s:

    1. Reboot if in CONF mode, do nothing in GW mode

  3. RESET Button pressed for 5s:

    1. Factory reset (wipe out WiFi and LNS credentials, though CUPS credentials are retained).

Troubleshooting

  1. Are you sure the correct ports were opened on the network?

  2. Check the LED lights

  3. Make sure there are not typos in the hub board ID (ask customer to take a picture of the sticker at the back of the device)

  4. Check if the hub is connected to the correct network (on the switch)

  5. Check if there is network connectivity on the patch in the switch (aka: connect the cable of the patch to your pc)

  6. Replace a non-working hub with one that is confirmed working

    1. If the non-working one is connected to the patch of the working one and this works: there is an issue with the patch/switch

    2. If the working one is connected to the patch of the non-working one and this works: there is an issue with the hub

Hub provisioning

If your hub is not showing up on /wiki/spaces/KB/pages/492072, make sure to communicate both the device EUI and the "WiFi password" (authentication code; that is printed on the sticker on the back of the device) to the Spacewell support team.

The Device EUI is the first number (58A0…) mentioned on the sticker.

Ideally just send a picture of the information on the back to Spacewell Support.
