If you are not sure if thingsHub receives any device data from the network server (Loriot, Kerlin, TTN The Things Network) you can look into the following two aspects:

"last_data_received" message from network server connector

The network server connector has a "last_data_received" object which can show you when it does receive a message for the last time and via the "raw" field what message it does receive:

{
  "auto_activate": true,
  "config": {
    "...": "..."
  },
  "id": 2,
  "last_data_received": {
    "raw": "{\"cmd\":\"rx\",\"seqno\":183339,\"EUI\":\"A81758FFFE03735C\",\"ts\":1543597768324,\"fcnt\":16.....",
    "received_at": "2018-11-30T17:09:28.342797Z"
  },
  "name": "Loriot thingsHub Demo",
  "type": "loriot"
}
CODE


Look into the network server connector log endpoint

We implemented a feature to show a little log which can show you the last 25 messages the network connector has received. Use the following rest call:

curl -X GET "https://{YOUR-INSTANCE}/api/v3/network-servers/connections/{CONNECTOR-ID}/log" -H "Authorization: Bearer {SECRET}"
CODE

The result will look like this:

{
  "logs": [
    {
      "raw": "{\"cmd\":\"rx\",\"seqno\":183358,\"EUI\":\"A81758FFFE03735C\",\"ts\":1543598728163,\"fcnt\":165594,\"port\":5,\"freq\":868100000,\"rssi\":-41,\"snr\":10,\"toa\":56,\"dr\":\"SF7 BW125 4/5\",\"ack\":false,\"bat\":254,\"data\":\"0100ee0222070def\"}",
      "received_at": "2018-11-30T17:25:28.191Z"
    },
    {
      "raw": "{\"cmd\":\"rx\",\"seqno\":183357,\"EUI\":\"A81758FFFE03735C\",\"ts\":1543598668176,\"fcnt\":165593,\"port\":5,\"freq\":867900000,\"rssi\":-37,\"snr\":9.5,\"toa\":56,\"dr\":\"SF7 BW125 4/5\",\"ack\":false,\"bat\":254,\"data\":\"0100ee0222070dec\"}",
      "received_at": "2018-11-30T17:24:28.197Z"
    },
    {
      "raw": "{\"cmd\":\"rx\",\"seqno\":183356,\"EUI\":\"A81758FFFE03735C\",\"ts\":1543598608181,\"fcnt\":165592,\"port\":5,\"freq\":868300000,\"rssi\":-35,\"snr\":8.5,\"toa\":56,\"dr\":\"SF7 BW125 4/5\",\"ack\":false,\"bat\":254,\"data\":\"0100ee0222070dec\"}",
      "received_at": "2018-11-30T17:23:28.205Z"
    }
  ]
}
