IOT Lightbulb hack

Repurposing IOT Lightbulb Chip For Anything

February 15, 2015 by 27 Comments

Home automation products have hit critical mass in the world of consumerism, and now suddenly everyone has a product you can control using some protocol or other. Cree (the maker of LEDs) has a rather cheap IOT-enabled bulb available in Canada and the US for the low price of $15 — not bad considering regular LED bulbs can run you that much, without wireless connectivity!

So if you want to outfit your house in smart lights — great. But what about other things? Well, [Mac Alpine] decided to crack open one of the bulbs to see if he could re-purpose the IOT board. Turns out, you can.

In fact it’s almost too convenient. It’s a remarkably small chip, about half the size of a silver dollar. And it features a small ZigBee radio module. All you need is a 3V power supply, and boom — you have an IOT module that is capable of PWM output. It features an Atmel ATSAMR21E microprocessor which communicates over the radio to a Quirky Wink hub — it can also be triggered using IFTTT.

Using The Wink Hub With OpenHAB

January 8, 2015 by 20 Comments

Spend enough time looking at home automation setups, and you’ll quickly find there are two competing philosophies. The first wants to put an Arduino on every light socket, with everything connected by cheap eBay radio modules. The second home automation philosophy requires astonishingly expensive hardware to talk to other expensive modules. The Arduino solution is a system that can be infinitely customizable, and the commercial solution talks to ‘the cloud’ for some strange reason. There is no middle ground. At least there wasn’t until [Eric] started poking around and looked at a few hardware solutions.

[Eric] was looking to control some GE Link bulbs through his phone, computer, or through the Internet. They’re supposed to be the best bulb on the market in terms of price and performance, but they can only be controlled with a Zigbee. This lead [Eric] to an interesting hack that gave all owners of the Wink Hub local control of their devices. From [Eric]’s research, this was the only way his lighting wasn’t dependent on ‘the cloud’.

Local control of the Wink was only possible after [Eric] read a post on rooting the Wink (and this post from a few days ago). Because the device could be rooted, and the fact that [Eric] already has a few things in his house integrated with OpenHAB, the choice on how to proceed with controlling a few Zigbee enabled lights was easy.

Once [Eric] got the light bulbs talking to the Wink, integrating them with the rest of the devices in his home was easy. The new bulbs are activated with his Arduino motion sensors, door sensors, and can be controlled via smartphone or by voice control. The Wink can also be completely disconnected from the Internet. A good idea, because the ability to turn a light on and off should not be dictated by the quality of your Internet connection.

A Better Way To Hack The Wink

January 5, 2015 by 33 Comments

If you’re looking for Home Automation appliances, you might want to check out the Wink Hub. It’s fifty bucks, and has six radios on board: WiFi, Bluetooth, Z-Wave, Zigbee, and 433MHz Lutron and Kidde. That’s an insane amount of connectivity in a very cheap package. It’s been pwnzor3d before, but dinnovative has a much better solution for getting root on this device.

Earlier methods of rooting the Wink involved passing commands via URLs – something that’s not exactly secure. The new method leverages what’s already installed on the Wink, specifically Dropbear, to generate public keys on the Wink hub and getting that key onto another computer securely. The complete exploit is just a few lines in a terminal, but once that’s done you’ll have a rooted Wink hub.

Even though the Wink hub has been rooted a few times before, we haven’t seen anything that leverages the capabilities of this hardware. There isn’t another device with a bunch of IoT radios on the market for $50, and we’re dying to see what people can come up with. If you’ve done something with your Wink, send it in on the tip line.

Skyscraper Tetris Lets The City Know How Good Or Bad You Are

January 1, 2015 by 16 Comments

If you’ve clocked one-too-many hours at Tetris, it might be time to show the world your skills on this skyscraper-sized display on the Shell Centre in London. [Benjamin], [Tom], and their “army of volunteers” took to the Shell building and assembled their super-screen from a collection of 182 networked wireless lightbulbs, some tracing paper, and mylar to create a playable interface from the Jubilee Gardens below.

[Benjamin] doesn’t deliver many of the technical details on his post, but he does give us an overview. He achieves full wireless coverage of all floors by spacing out 14 TP-Link WR702n routers, each running the same version of OpenWRT. This interface wasn’t [Benjamin’s] first choice, as he would’ve preferred to tap into the building’s existing wireless network; unfortunately, he was left without support from the building’s network team. Equipped with a large donation of wireless bulbs controlled by a central bridge, [Benjamin’s] Python-adaptation of Tetris can refresh the building about about 1-to-2 frames per second. Given his description of the bulb interface, we suspect he’s using the all-too-familiar Philips Hue smart lightbulbs to illuminate the building.

In case you haven’t heard of Faraday’s Christmas Lectures, they’re the UK’s nationally broadcasted “science special” featured at the end of the year and founded in 1825 by [Michael Faraday] himself. The goal of these Lectures is to introduce young people to some aspect from the sciences. We’ve seen giant Tetrises before, but not in a way that inspires such a young audience. We’re thrilled to see that hacking both in software (Python, LAN networks) and hardware (ZigBee, OpenWRT) made the cut for this year’s special. After all, why should MIT keep all the fun to themselves?

If the building-scale is just too big for your taste, why not have a go on your oscilloscope?

DEFCON 22: Hack All The Things

August 9, 2014 by 21 Comments

This morning I went to a fantastic talk called Hack All the Things. It was presented by GTVHacker. If you don’t recognize the name, this is the group that hacked the GoogleTV. They haven’t stopped hacking since that success, and this talk is all about 20+ devices that they’ve recently pwned and are making the info public (that link still had oath when I checked but should soon be public).

The attacks they presented come in three flavors: UART, eMMC, and command injection bugs. I’m going to add the break now, but I’ll give a rundown of most of the device exploits they showed off. I found all amusing, and often comical.

SOAP Drama: Another Go At Crowdfunding

June 11, 2014 by 73 Comments

SOAP

SOAP, the people behind what was initially a sketchy Kickstarter that turned into something reasonable is having another go at crowdfunding their touchscreen router with every radio imaginable. This time, however, they’ve crossed all their ts and dotted all their lowercase js to turn what was a very…. odd Kickstarter into something really cool.

The original specs of the SOAP router were impressive – basically, a touchscreen tablet with an ARM Cortex A9, USB 3.0, 802.11ac, gigabit LAN, and every radio module you could imagine. The goal, of course, being a completely open, hackable home automation system capable of talking to Zigbee and Z Wave, and X10 modules, all while being an easy to configure 802.11ac router with a touchscreen. It’s a great idea, and considering you could spend $200 on an ac router alone, without all the radio modules and touchscreen.

Judging from the updates to the original Kickstarter, the SOAP guys have come a long way in three months. They’ve moved away from a custom-designed iMX6 board to a Congatec System on Module in a move that could be described as the smartest move in the history of Kickstarter-funded consumer electronics. They’ve also fixed the Ethernet bandwidth limitation of the iMX6, although there’s no word on how that works.

To be fair, the SOAP Kickstarter should be studied by business students as the exact opposite of how you should run a Kickstarter. When the project first went up, there were inconsistencies that ranged from not having a functional prototype to lifting images from unrelated open source projects. In the past three months, though, it looks like the team has managed to pull something together. Whether or not the SOAP router will see the light of day remains to be seen, but the team is now in a much better position than they were three months ago.

SOAP: The Home Automation Router And Kickstarter Scam

March 7, 2014 by 141 Comments

How would you like a 7″ tablet with a Quad-core ARM Cortex A9 processor, USB 3.0, 32 GB of storage, 802.11ac, four ports of Gigabit LAN, Bluetooth 4.0, NFC, SATA, HDMI, built-in Zigbee and RFID modules, a camera, speaker and microphone, all for $170? Sound too good to be true? That’s because it probably is. Meet SOAP, the home automation router with a touchscreen, that’s shaping up to be one of the largest scams Kickstarter has ever seen.

There have been a few threads scattered over the web going over some of the… “inconsistencies” about the SOAP kickstarter, mainly focusing on the possibility of fake Facebook likes and Twitter followers. There’s also the question of their development process: they started building a router with an Arduino, then moved on to a Raspberry Pi, a Beaglebone, Intel Atom-powered Minnowboard, the Gizmo Board, PandaBoard, and Wandboard. If you’re keeping track, that’s at least six completely different architectures used in their development iterations. Anyone who has ever tried to build something – not even build a product, mind you – will realize there’s something off here. This isn’t even considering a reasonably accurate BOM breakdown that puts the total cost of production at $131.

The most damning evidence comes from screenshots of the final board design. These pics have since been removed from the Kickstarter page, but they’re still available on the Google cache. The SOAP team claims they’re putting USB 3.0 ports on their board, but the pics clearly show only four pins on each of the USB ports. USB 3.0 requires nine pins. A closer inspection reveals these screenshots are from the files for Novena, [Bunnie Huang]’s open source laptop.
