Python client for Relayr API
Welcome to the relayr Python Library. The repository provides Python developers with programmatic access points to the relayr platform.
You can install the library using one of the following methods, with the help of Pip:
You can download the very latest version of the repository from GitHub:
pip install git+https://github.com/relayr/python-sdk
You could also use the following to install the package from the Python Package Index:
pip install relayr
Receiving data via MQTT will work only for Python 2.7 and above due to limited suport in paho-mqtt for TLS in Python 2.6.
Receive a 10 second data stream, from one of your WunderBar sensors (device). In the example below the device does not have to be a public one in order to be used. You can obtain your device IDs from the relayr Dashboard My Devices section:
MQTT style (new)
import time from relayr import Client from relayr.dataconnection import MqttStream c = Client(token='<my_access_token>') dev = c.get_device(id='<my_device_id>') def mqtt_callback(topic, payload): print('%s %s' % (topic, payload)) stream = MqttStream(mqtt_callback, [dev]) stream.start() time.sleep(10) stream.stop()
PubNub style (old)
import time from relayr import Client c = Client(token='<my_access_token>') dev = c.get_device(id='<my_device_id>').get_info() user = c.get_user() app = c.get_app() def pubnub_callback(message, channel): print(repr(message), type(message)) conn = user.connect_device(app, dev, pubnub_callback) conn.start() time.sleep(10) conn.stop()
Switch a device’s LED on/off
from relayr import Client c = Client(token='<my_access_token>') d = c.get_device(id='<my_device_id>') d.switch_led_on(True)
