How does Ring communicate with connected devices # IoT

light-bulbWhen you leave home, are you sure the lights are turned off? With Ring, you can check it with a video camera and adjust them simply by sending a text message through live chat. Save energy!

Within an hour, a Savoir-faire Linux expert has built a device that allows him to control the lighting in his living room, while he is at the office. As Adrien Béraud has set his Ring account to automatically accept every call, he can see his living room remotely by simply initiating a video call to his home computer. He can then check if the lights are on, and turn them off as needed.

A simple device crafted with open hardware

Ring-arduinoAdrien first connected lamps in his living room to the Internet using a small connected system Particle Core (type Arduino) and a relay expansion board (Relay Shield). As his lightning is associated with a three-way switching circuit, it can easily control lights, even in the case of Internet failure or in case of problems with the relay. He then added a few lines of code in the documentation of the relay to connect it the Internet.

With some command line, your lights are connected

Once connected, he types a command line in the terminal of his Linux computer. For example, to turn off (LOW) the first lamp (r1):

curl -d access_token=123412341234 -d params=r1,LOW

Light control with Ring’s chat can then be done with this Python script:

#!/usr/bin/env python3
import re, json, http.client, urllib.parse
from controler import DRingCtrl

PARTICLE_API_TOKEN = '[your_api_token_here]'
PARTICLE_REQ_URI = '/v1/devices/[your_device_id_here]/relay'
PARTICLE_REQ_RE = re.compile('^(r[0-4],(?:HIGH|LOW))$')

class LightRingController(DRingCtrl):
    def __init__(self):

    def tryParticleReq(self, params):
            conn = http.client.HTTPSConnection('')
            p = urllib.parse.urlencode({'access_token': PARTICLE_API_TOKEN, 'params': params})
            conn.request("POST", PARTICLE_REQ_URI, p, {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"})
            ret = json.loads(conn.getresponse().read().decode())['return_value']
        return ret

    def onIncomingMessage(self, callid, ufrom, message):
        super().onIncomingMessage(callid, ufrom, message)
        msg = message['text/plain']
        res =, msg)
        if res:
            op =
            print('Command:', op)
            ret = self.tryParticleReq(op)
            self.callmanager.sendTextMessage(callid, {'text/plain':'Got: '+str(ret)}, False)

if __name__ == "__main__":
    ctrl = LightRingController()

IoT: endless possibilities

Many uses are possible, from simple to complex. For example, a Ring call can directly control lighting with such a script:


class LightRingController(DRingCtrl):


    def onCallStateChanged(self, callid, state, statecode):
        super().onCallStateChanged(callid, state, statecode)
        if state == "HUNGUP":
        elif state == "CURRENT":

So imagine what you could do if your Ring software was connected to your heating or your garage door… The possibilities are endless!

Open Source Interview With Karen Sandler at the Montreal Gnome Summit 2013


On October 12, 2013, we had the pleasure to host the annual Gnome Summit in Montreal and, in the evening, we organized a community meet-up in our offices. Gnome core developers and local hackers met, had food, a couple of drinks and quite a lot fun together. The event was supposed to end around 9:00 PM but, finally, it lasted beyond 11:00 PM. 🙂

During the meet-up Karen Sandler, Executive Director of the Gnome Foundation, kindly answered our questions about the Gnome Summit and the state of Open Source in the world. In this interview she explains why the annual “Boston” Summit now takes place every second year in Montreal, and briefly presents the main technical issues that were on the agenda during the weekend — especially desktop accessibility. Finally, she shares her thoughts on the state of Open Source in the world and how much work still has to be done to live in a better digital world.

The Montreal Gnome Summit 2013 was sponsored by the FQCIL (Quebec Free Software Community and Industry Federation) and Savoir-faire Linux. You can read more in our previous post.

Interview Transcription

Source: Sven Werlen, Vice-president, Enterprise Solutions, Savoir-faire Linux

Last January, we introduced the Liferay User Group with James Faulkner, Liferay’s Community Manager, and so we decided to create a group in Montreal to represent Quebec as a whole – the Quebec Liferay users and developers. The first meeting of this user group will be held on February 13. The goal is ultimately to define the bases, how often we want to meet in the year, and what we want to present.

A “User Group”, what is it? It is primarily a set of services on the site which basically allow to meet, by means of a forum, and also to promote events which are organized either in Montreal, or in Quebec, and maybe later, also in Ottawa.

We decided to start our Liferay User Group because of the success in the last two years of this portal in Quebec. We realize that there are more and more large organizations that have decided to launch portals with Liferay. So a critical mass of users is starting to emerge as well as of developers. And so we thought it appropriate to create a group of users, not only to promote but also to share ideas, to exchange experiences on the product and therefore, ultimately, to improve the Quebec expertise in this open source technology.

A user group in Montreal, and Quebec in general, can also allow to contribute to the product and provide local wealth by providing patches or modules. The application marketplace was launched last year in 2012, so any company in Quebec can promote and improve the product and offer applications.

This user group will also help to identify a number of requirements that are common in Quebec and possibly offer them to Liferay so that they are are integrated natively in the product. I think especially of the translations that have been made — contributions to the French-Canadian translations are frequent — but other modules are more specific to Quebec and could therefore be integrated into Liferay.

First OpenERP Montréal Meetup at Savoir-faire Linux

Mark your calendars! The first OpenERP Montreal Meetup is scheduled for October 10th. Savoir-faire Linux has taken the initiative to launch this monthly community of practice to allow Quebec businesses to discover the tremendous potential of OpenERP, and to share their needs, knowledge and projects in an open group, on an informal but regular basis.

In summary, OpenERP is an open and free software suite of integrated business management. It contains some 700 application modules, from sales to client relation management (CRM), project management, warehouse management, production, accounting, human resources and more. This solid enterprise resource planning (ERP) platform is developed, moderated and supported by OpenERP, a Belgian company with offices in Luxembourg, India and the United States; together with the help of a strong community of more than 1500 individuals and 400 organizations in over 70 countries – including a dozen in Canada.

During this first meeting, which will be held in the Montreal offices of Savoir-faire Linux, Pierre Lamarche – an ERP functional consultant – will present the sales and CRM modules. The presentation will in fact be the starting point of a round of informal conversations on the product, its features and its ecosystem, as well as on the future of the event itself.

Current and potential users interested in ERP – business managers, IT directors, integrators and developers – are cordially invited to participate in this “meetup”. Its relevance and success rely on the richness of exchanges, the openness of the participants and their collaborative spirit in developing a shared network and heritage.
