Integrate with Ikea Trådfri Gateway as bridge to communicate and control connected Ikea's ZigBee based smart lights, switches, and sensors

[Hedda]

Ikea have just released a new app-controlled network-attached home automation hub which will serve as a Gateway to control its new "Trådfri" series of affordable smart lights / lightbulbs, switches / remotes, and sensors, which in turn so far all uses ZigBee based protocols. These products are set to be released on the 31st of March 2017 in selected countries around the world.

"Trådfri" means 'wireless' in Swedish, and Ikea have so far announced this very aggresivly low-priced network-attached (Ethernet) "Ikea Trådfri Gateway" home automation hub in their "Tradfri" series, as well as a wireless Motion Sensor Kit (that have integrated light sensor too), a wireless Dimmer Remote (which is accelerator-based), a wireless multi-switch remote, and several smart light bulbs of different formats and even a few unique panel lights. All these products will then be released in most other contries worldwide too as Ikea steps up manufacturing (and irons our the initial software bugs I guess).

Ikea had already leaked news about this upcoming gateway/hub more than 6-months ago, during the summer or 2016, and at that time they also revealved that they will use ZigBee and keep validated access to the gateway/hub as open as possible, including providing an open API for this network-attached home automation hub.

Ikea in Sweden are first to post this news about the network-connected Home Automation Gateway / Hub, but again these products will become available worldwide. Here is link to the Swedish links:

Link are in Swedish for Ikea Sweden site, but the PDF manuals on each page are available in English and many more languages, however they don't say much other than mounting instructions.

Reason why I think that this news being interested is Ikea's aggresive pricing might them the first to make two-way communication home automation really affordable for almost everyone while still following all the electrical safety and wireless communications regulations in all countries, as they are today well known to have very low prices yet good manufacturing quality items.

UPDATE 1: Sound as Ikea Trådfri Gateway software uses the Cypress WICED IoT platform SDK (formerly Broadcom WICED IoT platform before acquired by Cypress http://www.cypress.com/internet-things-iot ) and have choosen to base their implementation on OMA (Open Mobile Alliance) and Eclipse recommended IoT protocol standards of those three logical components; CoAP (coaps) and DTLS layers of the LwM2M (Lightweight machine-to-machine) security model for IoT device management and protocol stack, using IPSO (IP for Smart Objects) Smart Object Guidelines provide a common design pattern. That is, looks as if the communication between Android/iOS app and the Gateway takes place via OMA Lightweight M2M (LwM2M) wrapped in CoAP with DTLS.

Update 2: Jaime Jiménez (from the company Ericsson) who is an active member of the IPSO Alliance’s working group and part of the team that published the IPSO Smart Object Guidelines, posted this great teardown of the Ikea Trådfri implementation:

For those who don’t know, LWM2M is a protocol built around CoAP and use for managing devices. So things like firmware upgrades, error reports, etc. Apart form the management interfaces, LWM2M also adds a very simple Object Model for managing those devices. IPSO expands that set of Objects so that you can have application information too (e.g. sensor readings, commands, etc). IPSO defines objects and resources that map to device properties.

Particular pay attention to the IPSO Light Control objects:

If you want to know more about the wealth of data models out there you can check the IoTSI Workshop as a reference.

LwM2M (Lightweight machine-to-machine) meanwhile is a system standard in the Open Mobile Alliance. It includes DTLS, CoAP, Block, Observe, SenML and Resource Directory and weaves them into a device-server interface along with an Objects structure based on IPSO Smart Object Guidelines.

IPSO provide common object model for interoperability of IoT Devices and Applications.

For testing of the gateway purpose i'm using the californium.tools (https://github.com/eclipse/californium.tools) and in my program i use the coap client implementation of the californium library.

Hi, I've been following this (nice) discussion from the very beginning. The thing is that I would be interested in running some (source) code directly (bypassing the gateway) on the bulbs. Do you think it would be possible? (a piece of software running continuously in the bulb... if the temperature of the bulb falls down, then change the color to blue)

Hello! Tons of useful info and links in the thread, thanks! I have been playing with the new Trådfri Color bulb trying to figure out why it would not show the whole spectrum and found the answer by cracking one open. It does not have green LEDs. I have put some code, info and pictures here: https://github.com/ffleurey/ThingML-Tradfri so that you do not have to vut your own bulb :-) Cheers!

[gabrielsson]

@ffleurey Really nice library. Great that you have put the effort in to make the UI, really fun and works great.

Very informative thread. I'm trying to generalize some of the findings above into a handy CoAP Shell (https://github.com/tzolov/coap-shell) with some initial Ikea gateway support as well. https://www.youtube.com/watch?v=zhEGFfCJwTg&feature=youtu.be

With the implementation of OpenHAB, Which has Tradfri connectivity, I will suggest that is the path to implement this.

See https://www.openhab.org
