    XMPP for IoT: Visualisation of Meteorological Live Data for Renewable Energy

    pubsub.movim.eu / berlin-xmpp-meetup · Tuesday, 11 May, 2021 - 15:29 edit

Dan and Tim will present a beautiful web application based on Strophe.js and Flot.js to visualise live measuremen data transmitted via XMPP PubSub/PEP. This is not about instant messaging at all, this is IoT, but security included.

When? Wednesday, 2021-05-12 18:00 CEST (always 2ⁿᵈ Wednesday of every month)

Where? Online, via our MUC (xmpp:berlin-meetup@conference.conversations.im?join). A Jitsi video conference will be announced there.

See you then!

With the name Smarter, you might expect a network-connected kitchen appliance maker to be, well, smarter than companies selling conventional appliances. But in the case of the Smarter’s Internet-of-things coffee maker, you’d be wrong.

After just a week of effort, the unqualified answer was: quite a lot. Specifically, he could trigger the coffee maker to turn on the burner, dispense water, spin the bean grinder, and display a ransom message, all while beeping repeatedly. Oh, and by the way, the only way to stop the chaos was to unplug the power cord. Like this:

“It’s possible,” Hron said in an interview. “It was done to point out that this did happen and could happen to other IoT devices. This is a good example of an out-of-the-box problem. You don't have to configure anything. Usually, the vendors don’t think about this.”
