[CONNIO EDGE] Add edge nodes to send data from device to the platform

bmrb commented 4 years ago

[See next comments for changes. We might need to change node fields accordingly]

This is for the cases where Nodered works in a device. Selected device will write a data point into the selected property using device key meaning we will be able to write into all device properties including private and protected ones.

If property is selected make sure that the flowing value is converted to a data point as expected by the platform.

The data will be written via MQTT API.

Details

We need only 3 fields on this dialog:

Connio mqtt endpoint address and port (default will be mqtt.connio.cloud + 1883)
Device key id
Device key secret
Property name

The node must have only one input.

Example usage is as the following:

IoT enthusiast will deploy NodeRed to his device (e.g. RaspPi).
He will install connio package
From the "Connio Edge" group he will select this one
He will install another node to read IO ports of the RaspPi
He will connect the output of the IO PORT reader node to the input of this one
our node will write flowing data into the given device and property via MQTT

Important

Property combo will be populated with device's properties automatically when the credentials are provided via REST API
Device id will be collected automatically using given credentials via REST API
The very first item in the list will be . When selected that means the developer want to provide data in JSON format.

For example, if temperature is selected in the list, the MQTT topic will as following: .../devices/{id}/properties/temperature and the data will be in raw format.

if JSON is selected in the list, the MQTT topic will as following: .../devices/{id}/properties/json.

See the documentation for details.

Connio MQTT connection will be established using the device credentials.

Property and Method nodes are going to have input and output points.

User might be able to choose json instead of property or method name in order to send multiple data points from a single node.
