Passed the Grand central bus station a morning. It was 4 Celsius (39 F) not cold at all! To my stunning eyes I found these infra-heaters above the pavement. Couldn’t find the power reading but I would guess at least 4kW
WE LIVE IN SWEDEN, Get dressed!!!
hard to work with energy-efficiency when there is so many stupid decisions made. I donate my gloves and cap.
Working my way in to the villa storage I found the savings from high-school extremely fun.
Wish you all a very merry christmas and a nice new year.
Had my own home grown tree this year. It is huge, beautiful smell nice, ecological !!
And my daughter likes to play under it
Being a keynote speaker…. I have had so many sessions through my life but never been a keynote speaker. I must say it is with great honour.
More info on the conference gogo6live conference
- Many very talented people attended
- To hear me speaking
Everything was live streamed to a broader audience online two
The conference was very interesting and my keynote slides are on slideshare

I love the platform meetup.com it’s really getting the right people to the right spot at the right time.
As a engaged person I love talking to other engaging people and the meetups I’ve been to and the one’s I have organised is just about that. we have so many ways of communication in these days but the meeting between people are still the best way to ”get things done” and inspire each other. I would have loved to be able to participate in all at the same time being allower the world at the same time.
If you havent registered yet do it now on meetup.com and find an interesting topic and join an evening meeting on any topic.
I’ve participated in
The-San-Francisco-Internet-of-Things-Meetup Design talks
XMPP and the internet of things London meetup
Python IoT hacking with XMPP
IoTStockholm chatty things
pysthlm Big data
SF bay area XMPP chattering things
Been using my Prius Ev plug-in since December and it getting good results. I’m using 0,3 litre / 10 kilometre petrol and 335 Wh / 10 kilometre gives me a total cost in swedish kr of 5,04 kr. The trick of being able to charge is of course one of the major issues.
This is the way to charge at IKEA uppsala.
Contact me if you need a GSM connected electricitymeter to measure all the electricity you charge. (The extra grey box on the charging cable)
Being at the Advanced Energy Conference 2013. I started to use the term 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.
Historically there has been numerous unifying architectures that “solves everything”. In the era of smart homes and buildings, technologies such as Lonworks and KNX, promise to give a solution for connecting everything. But that is only true as long as everybody adheres to the same technology and as we know that will never happen!
Only IP has managed to be the common denominator, regardless of the communication layer. Regardless how good the proprietary technology is for example zigbee and KNX, they all need an IP-gateway. Even equipment in buildings such as pumps and fans start to have IP connectivity instead of proprietary communication buses. In later years the thrive to connect things to the Internet, all players have created IP based connectivity to cloud services.
To bridge between business sectors and protocols different middleware projects has emerged. OSGI was one of the first, fi-ware.eu a big one at the moment. These are all good intentions but they all fail due to the large implementation work to comply to the middleware framework. Developers tends to go for the “cheapest solutions” skipping good designed frameworks for easy hacked tools.
I’m now taking part in the fantastic development of a solution that actually can be the solution using XMPP to solve real interoperability between business silos take a look at the iea.sust.se project and the effort att xmpp.org code available at github
Had a fantastic meeting with my teacher Karl-Olof Elmsjö from 7th grade. He gave me much of my interest and curiosity towards technology. We talked for hours around old technology and I must share this fantastic smart home history. The house is controlled via phone dial pads. When dialling different numbers the garage-door opens and lights are turned on and of via a phone switch board in the cellar. Karl made this true in is own homes in the 1970’s.
And still the main achievement in smart homes are the smart plug for controlling lamps, http://www.vattenfall.se/sv/smartplug.htm
