MicroPython library which provides easy connectivity to WolkAbout IoT Platform.

Supported device communication protocol(s):

  • WolkAbout Protocol

Requirements

WolkConnect-MicroPython depends on an implementation of an MQTT client. This dependency can be satisfied by using MicroPython's umqtt.simple. Alternatively, use umqtt.robust or Pycom's mqtt.

Installation

  • Clone this repository:
git clone https://github.com/Wolkabout/WolkConnect-MicroPython.git
  • Copy wolk.py into the lib directory of your board.

Example Usage

Establishing connection with WolkAbout IoT Platform

Create a device on WolkAbout IoT platform by using the provided Simple example device type.
This device type fits main.py and demonstrates the sending of a temperature sensor reading.

from [mqtt] import MQTTClient
import wolk

CLIENT_ID = hexlify(unique_id())
# Setup the device credentials which you received
# when the device was created on the platform
wolk.DEVICE_KEY = "device_key"
wolk.DEVICE_PASSWORD = "some_password"

# WiFi connection is required before this step

MQTT_CLIENT = MQTTClient(
    CLIENT_ID, wolk.HOST, wolk.PORT, wolk.DEVICE_KEY, wolk.DEVICE_PASSWORD
)

WOLK_DEVICE = wolk.WolkConnect(MQTT_CLIENT)

WOLK_DEVICE.connect()

Adding sensor readings

WOLK_DEVICE.add_sensor_reading("T", 21.17)

Data publish strategy

By default, 20 readings are stored in memory but this can be changed by specifying a different number when creating an instance of WolkConnect like so:

WOLK_DEVICE = wolk.WolkConnect(MQTT_CLIENT, storage_size=50)

Stored sensor readings and alarms are pushed to WolkAbout IoT Platform on demand by calling:

WOLK_DEVICE.publish()

Disconnecting from the platform

WOLK_DEVICE.disconnect()
