Being friend with an Intel Edison and have Secure access over XMPP

Today I started the amazing Intel Edison board to try and use the XMPP-IoT tools to connect it securely over internet and it worked like a charm.

inittial setup and configuring for wifi was done with the instructions from Intel, i used the mac version. It didn’t take long to get i hooked upp to wifi. Activate a password on root for it to enable remote ssh

 Get the software started

I am using a fork from the python SleekXMPP package. Just wget the SleekXMPP package with the XMPP-IoT extensions from my Github. Python 2.7.3 is  already on the machine. The GPIO package ”mraa” for python is also installed from the beginning very handy.

You need two XMPP accounts on a server somewhere there are many https://xmpp.net/directory.php I usually use the swedish jabber.se. Create two accounts so they later can talk to each other.

in the /home/root folder on the Edison do:

wget --no-check-certificate https://github.com/joachimlindborg/SleekXMPP/archive/xep_0323_325.zip
unzip xep_0323_325.zip

Start off with blinking the magical led

Go down in the example katalog and start the python Edison example with your xmpp account.

cd SleekXMPP-xep_0323_325/examples/IoT/
python IoT_GPIODevice_Edison.py -j yourfirstaccount@domain.com -p password -n test_device

should look something like this

Now direct your browser to https://conversejs.org/# login with the other xmpp user you created. yoursecondaccount@domain.com.  Then choose to add a contact and  provide the first account it should just accept and you can start chat with the device. use ”hi”, ”toggle” ”relay=true” and ”?”

If you have a RELAY and a PIR sensor wire them up to the board use GPIO pin 13 for the relay and GPIO 8 for the PIR you can see the PIR sensor changing

The journal logs keep filling up so I changed the journaling.conf

to restart a clean image but I failed totally the reflashed edison keeps all settings

I found dokumentation on the opkg package manager very useful, especially the command to remove a package with dependencies

IoT, will we ever leave the silos?

Internet of Things is today huge, but as always it is hyped and includes almost every-Thing. Today we are back in the 1990’s creating business models based on a connected thing, letting the mainframe investigate and use our data. And for me as a customer I again, as it was in the 1990’s, end up with a bunch of incompatible systems, today called apps.

from Postscapes I found a very good sentence

iq option come vincere When data is removed from siloed warehouses and is able to be identified and shared between products and services like it is within the current Internet architecture a true Internet of Things can emerge.

The explosion on apps on the phone is a result of innovation, based on the easy accessible sensors on the phone such as, camera, temperature, gps, gyro etc. Imagine the services that could be created if all IoT things was as easy to use as if they all were in the same phone? And in that case which phone?

We will always need integration and a way to interconnect system, IoT also needs that and no company based solution should win expecially if they own a phone. Please go for open solutions when you create your things, from my heart I think that XMPP-IoT is one of the more beautiful solutions.

Chatty things

Being at the Advanced Energy Conference 2013. I started to use the term estrategias opciones binarias 2017 chattering things or chatty things this is a very good abstract view of whats happening in the Internet of Things world.

The billion devices that is to be connected will in classical way be connected to private clouds which is just somewhat better than the old legacy, proprietary protocols. We are getting an exploding number of slightly different web api’s. Creating new web mashup services will therefor never happen since you need to support so many protocols.

The solution is to leverage the instant message paradigm and the XMPP.org standard. To be used by all things letting them chat with each other. A sensor can be friend with an actuator regardless of its origin or business domain. A humidity sensor in an alarm system could then easily be connected to the ventilation system.

When these chattering things are available in an interoperable way there truly is a possibility for real smart energy services to happen without the need of adding more hardware. You just let the sensor doing a friend request to the energy service. The just let them start chitchatting.
