This project is a MicroPython library that provides an client for the Device API of ThingsBoard open-source IoT Platform.
The library consists of a thin wrapper around the MicroPython MQTT module, umqtt.robust.
To install using pip:
import upip
upip.install('thingsboard-micropython')Client initialization and telemetry publishing:
from uthingsboard.client import TBDeviceMqttClient
# See examples for more authentication options
client = TBDeviceMqttClient('demo.thingsboard.io', access_token='test01')
# Connecting to ThingsBoard
client.connect()
# Sending telemetry
telemetry = {'temperature': 41.9, 'enabled': False}
client.send_telemetry(telemetry)
# Checking for incoming subscriptions or RPC call requests (non-blocking)
client.check_msg()
# Disconnecting from ThingsBoard
client.disconnect()More examples can be found in examples directory.
- SSL and QoS (0 or 1) as supported by the backend MQTT library, umqtt.robust.
- All Device API's, except Provisioning.
- Tested only on ESP32 board running MicroPython v1.16 generic.
This library is an adapted version of the official ThingsBoard client SDK for Python, to run in MicroPython.
