The Node-RED flow is quite simple. Only a few nodes.
Let me share with you what is interesting in this flow.
First off all a Freeboard node has been added with the name "Wio Link". This kind of node has no parameters at all. It just send to Freeboard environment the JSON object received in its input. What makes this datasource interesting is the payload configured in the inject node. The field Payload in the dialog box of the inject node has been (manually) populated with the result of the HTTP Request "Scan Drivers". The API "Scan Drivers" provides a JSON object that shows all the Grove modules that are eligible to be connected to Wio Link. Some interesting parameters of this object are: a link to a picture of the module and the module name (among many others). The idea of creating this datasource is to build a foundation to easilly add in the dashboard (Freeboard) any the Grove modules that I want to play with.
For this flow I hard coded the node token as the msg.payload (string format) of the inject node named "Fire" . This string will be used as the value for the "Authorization" property in the HTTP Request. Note that it is necessary to prefix the token itself with the literal "token".
msg.headers = {"Authorization": msg.payload};
I configured an interval of 5 minutes for pooling the sensor data. It means that every five minutes a new HTTP Request will be sent out to read the data from the sensor.
Two other nodes of type "Freeboard" have been added to the logic.
They will send to Freeboard the temperature and humidity read by the HTTP Requests.
This is pretty much the Node-Red flow. I won't be posting the screenshots that show how the dashboard has been configured since this would be very time-consuming. Maybe I will make a video on that and post on my channel on YouTube (as soon as I manage to buy a decent mic to add sound).
Below the flow that can be copied and imported to your Node-RED.
