Python client for Relayr API

Project Description

Welcome to the relayr Python Library. The repository provides Python developers with programmatic access points to the relayr platform.

These include access to the relayr cloud via the relayr API as well as direct connection to the relayr WunderBar sensors, via Bluetooth Low Energy (using BlueZ on Linux, still very experimental).


You can install the library using one of the following methods, with the help of Pip:

  1. You can download the very latest version of the repository from GitHub:

    pip install git+
  2. 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])

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)

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>')
