#Davra integration and ZM1-EVA Evaluation Board

In this demo we will publish data using the ZM1-EVA Evaluation board, create and enable a Davra integration and send the data to a Davra dashboard.

In this tutorial, we will be using:

  1. Zerynth SDK - this includes VSCode with the VSCode Zerynth extension, which is our default development environment.

  2. Zerynth Device Manager (ZDM) - it helps you register, organize, monitor, and remotely manage IoT devices at scale.

  3. ZM1-EVA - Evaluation Board

1. Import the Davra project​

Connect the ZM1-EVA to the PC then clone this GitHub repository containing a Zerynth project that configures a ZM1-EVA Evaluation board for sending humidity and temperature readings from a DHT11 to the Zerynth Cloud.

Install and open the Zerynth SDK, press Ctrl+Shift+P and search for Zerynth: Login; then login to the Zerynth Cloud or create a new account if you don't have one.

To open the project, click on File -> Open Folder from the top menu and search for the path of the downloaded GitHub project.

2. Enable the device and configure it to send data​

To be sure that the ZM1-EVA device support is enabled, press Ctrl+Shift+P and search for Preferences Open User Settings. This will open a dialog with two tabs (User and Workspace). Click on the Expansion menu item under the "User" tab, you will see a new menu. Click on "Zerynth" item. Ensure that the ZM1-EVA board is enabled.

Provision and configure the Device​

You only need to provision your device once for the lifetime of the device.

Just click Provisioning on the Zerynth Control Panel, you will be asked to create a cloud device, give it a name like my-iot-davra-device and accept the confirmation dialog and wait a little.

After provisioning, in the control panel, You'll find the cloud device is now assigned an ID.

Run the project​

Open the main.py file in the project folder, and edit the rows 49 and 50 typing your WiFi SSID and password.

At this point you are ready to click on the Run button! Your device will be automatically configured and it will start publishing data to the Zerynth Cloud.

If you open the device page from the Zerynth Cloud, you will see real time data sent from your device!

Create Davra integration​

The last step to receive the data published from the device to you Davra dashboard is to create a Davra Integration.

  1. Open the Zerynth Cloud and select the workspace containing the device you configured before (probably the "default" one).

  2. Click on the Integrations button from the navbar on the left.

  3. Click on the + New button on the top right, then select Davra from the dialog. zm1_enabled

  4. Choose a name for your integration, check the url, type your personal Davra token and that's all! Your data will be automatically forwarded to your Davra dashboard.
