For IoThub, LuvitRed contains the 'iothub' in- and out-nodes. The documentation on how to use these nodes can be found on cloudgateuniverse or under the 'Info'-tab in LuvitRed when the node is selected.
For this example we will use an 'inject' node and an 'iothub out' node.
1. Make sure you have everything ready at the azure side: Create a device and give it an ID and so on.
2. Install the 'Microsoft Device Explorer' tool as described in the info tab.
(Here are some instructions for this tool: https://github.com/Azure/azure-iot-sdks/blob/2016-06-03/tools/DeviceExplorer/doc/how_to_use_device_explorer.md#download)
3. Enter your IoT hub connection string and click update.
4. Once you find the device in the management tab of the device explorer, click on 'SAS'. The tool generates a string, wich you should completely copy and paste into the luvitRed iothub config: (make sure the TTL, time to live is set to your wishes)
When this is all taken care of, you should now be able to send a timestamp to Azure IoThub.
