The idea of these hubs is to connect to an existing (guest) Wifi or to set up a seperate wifi, analog to ethernet and VLANs.
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

Technical Requirements of the Hub

Mini hubs run on 2.4GHz

Open ports 7007; 8881-8887 in the firewall. These ports only need an outbound connection.

Following table lists the IP addresses that outgoing traffic (sensor data) goes to: List of IP addresses for outgoing traffic

(if you work with a 4G router (hotspot), client does not need to open ports, as they are open on the router. This way, you can set up a system that is completely disconnected from the existing IT infrastructure)

(in case of 4G, a 4G gateway is needed. This creates a WiFi network, please make sure this is allowed by the customer)

How to Activate the Hub

  • Press the reset button (small button at the back of the gateway next to the USB-C port) for 5 seconds until the LED blinks rapidly GREEN<->RED for a couple of times.
  • Hold the SETUP (button at the top of the gateway, next to the LED) for 10 seconds until the LED blinks rapidly in RED.
  • The gateway now exposes a WiFi AP whose SSID is MINIHUB-xxxxxx where xxxxxx is the last 6 digits of the gateway ID.
  • The password for this network is printed on the back panel of the device under WiFi PW.
  • After connecting to this network go to 192.168.4.1 using a web browser to access the WiFi config page:

  • Select the WiFi network and enter the password if it’s a closed network.

  • Select the “Save and Reboot” option.

  • If your config is right, the gateway will blink GREEN for a few seconds while it connects to this network.

  • Then, it will blink GREEN<->RED for a few seconds while it connects to the CUPS endpoint and fetches the necessary information to connect to the LNS traffic endpoint.

  • If your configuration was successful, the LED will be solid GREEN which means that the gateway is connected to the LoRaWAN network and is ready to handle packets (Spacewell Cobundu SPOC is able to check this)

 

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).

 

Hub provisioning

If your hub is not showing up on The Things Network (LoRa platform), 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 hardware manager.
