Async library for Plugwise stick

python-plugwise: An async python library to control Plugwise plugs Circle+ and Circle

This library was created to extent my Home Assisstant setup with the Plugwise stick to control the linked Circle+ and Circle plugs. As the primary goal is to support Plugwise nodes in Home Assistant, it can also be used independently.

There's no official documentation available about the protocol of the Plugwise so this library is based on partial reverse engineering by Maarten Damen and several other sources bitbucket.org/hadara/python-plugwise and openHAB

The latest version of the library is published as a python package on pypi and currently supports the devices an functions listed below:

Plugwise node	Relay control	Power monitoring	Comments
Circle+	Yes	Yes	Supported
Circle	Yes	Yes	Supported
Scan	No	No	Not supported yet
Sense	No	No	Not supported yet
Switch	No	No	Not supported yet
Stealth	No	No	Not supported yet
Sting	No	No	Not supported yet

When the connection to the stick is initialized it will automatically connected to Scan for linked nodes

I would like to extend this library to support other Plugwise device types, unfortunately I do not own these devices so I'm unable to test. So feel free to submit pull requests or log issues through github for functionality you like to have included.

Note: This library does not support linking or removing nodes from the Plugwise network. You still need the Plugwise Source software for that.

Install

To install run the following command as root:

python setup.py install

Example usage

The library currently only supports a USB (serial) connection (socket connection is in development) to the Plugwise stick. In order to use the library, you need to first initialize the stick and trigger a scan to query the Circle+ for all linked nodes in the Plugwise Zigbee network.

import time
import plugwise

CALLBACK_RELAY = "RELAY"
CALLBACK_POWER = "POWER"

def scan_start():

    def scan_finished():
        """
        Callback for init finished
        """

        def power_update(power_use):
            """
            Callback for new power use value
            """
            print("New power use value : " + str(round(power_use, 2)))


        print("== Initialization has finished ==")
        print("")
        for mac in plugwise.nodes():
            print ("- type  : " + str(plugwise.node(mac).get_node_type()))
            print ("- mac   : " + mac)
            print ("- state : " + str(plugwise.node(mac).get_available()))
            print ("- update: " + str(plugwise.node(mac).get_last_update()))
            print ("- hw ver: " + str(plugwise.node(mac).get_hardware_version()))
            print ("- fw ver: " + str(plugwise.node(mac).get_firmware_version()))
            print ("- relay : " + str(plugwise.node(mac).is_on()))
            print ("")
        print ("circle+ = " + plugwise.nodes()[0])
        node = plugwise.node(plugwise.nodes()[0])
        mac = node.get_mac()
        print("Register callback for power use updates of node " + mac)
        node.register_callback(power_update, CALLBACK_POWER)

        print("start auto update every 10 sec")
        plugwise.auto_update(10)

    # Scan for linked nodes and print all scan activities to console
    plugwise.scan(scan_finished, True)

## Main ##
print("start connecting to stick")
port = "/dev/ttyUSB0"
plugwise = plugwise.stick(port, scan_start)

time.sleep(300)
print("stop auto update")
plugwise.auto_update(0)

time.sleep(5)

print("Exiting ...")
plugwise.stop()

Usage

You can use example.py as an example to get power usage from the Circle+
