Guest Post: IKEA TRÅDFRI Smart Lights use IPSO Smart Object Models

Jaime Jiménez of member company Ericsson has been very active IPSO Alliance’s working group, especially the Semantic WG that published the IPSO Smart Object Guidelines. Perhaps it’s no surprise then that he’s on the leading edge of IoT implementations, and noted that IKEA’s new TRÅDFRI smart lights have implemented IPSO smart object models. Jaime explained:

There have been some press releases on the IKEA lights. I actually went yesterday to buy some of them to play around.

Here is a short excerpt from Jaime’s post:

Another interesting bit of information, is that it looks like the payload itself seems to use IPSO-like Objects as data model.

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. If we got to the IPSO repository and look in particular at the Light Control we can see that it allows a light to be turned on or off and its dimmer setting to be controlled as a % between 0 and 100.
