Raspberry Pi and ExoSense¶

Create a new IoT Connector¶

• Locate the ExoSense™️ Standard Connector Template in Exosite's IoT Marketplace.
• Select "CREATE IOT CONNECTOR" and pick a name for your new connector. In this example we will simply use 'myfirstconnector'

Identify connector ID and Hostname¶

In ExoSense:¶

• Inside of ExoSense, navigate to "Setup" -> "DATA SOURCES"
• Under "Device IoT Connectivity" locate your connector and note the connector id associated with it.
• Your hostname (replacing <connector_id>) will be :

https://<connector_id>.m2.exosite.io

Start ExoEdge¶

On Raspberry Pi¶

Configure Raspberry Pi¶

• When using Raspberry Pi, the recommended OS is Raspbian LITE
• Make sure your Raspberry Pi is on and connected to the Internet
• Make sure your Raspberry Pi will allow for SSH connection

sudo raspi-config

Update system and install pip¶

sudo apt-get update
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo python get-pip.py

Install ExoEdge¶

pip install exoedge
pip install exoedge_simulator

sudo apt-get install build-essential python-dev

Start ExoEdge¶

Run the following command, where:

• <DEVICE_SERIAL_NUMBER> is a unique identifier for the device
• <PRODUCT_HOST> is the URL/hostname we found above

edged -s <DEVICE_SERIAL_NUMBER> \
    -H <PRODUCT_HOST> \
    -i <DEVICE_SERIAL_NUMBER>.ini \
    go

Claim Device in ExoSense¶

• Navigate to the 'Devices' page from the Navigation Panel.
• Locate your device in the "Unused Devices" tab
• Select the device and a group to add the device too
• Press the "ASSIGN TO GROUP" button

Configure Device in ExoSense¶

Locate and select the device in the devices tab

Add a new channel by selecting the '+' button in the top-right corner of the channels tab.

Below is an example configuration to instruct ExoEdge to create a Sin Wave:

Where the app_specific_config is as follows:

{
    "function": "sin_wave",
    "parameters": {
        "period": 120,
        "amplitude": 10,
        "offset": 100
    }
}

After selecting "done" then "save", the configuration will be pushed to ExoEdge and ExoEdge will start reporting data back in a sin wave.

NEXT¶

• Create an asset on ExoSense
• Visualize the sin wave with a dashboard on the ExoSense asset
• Utilize the ExoEdge Modbus Source
