Using ZLight2 with Philips Hue hub

Manuel Pietschmann

Hello,

I was reading the wiki article about ZLight and ZStack and luckily it seems that it's possible to use the light with the Philips hub. (at least the headline "Changes Require for a ZStack-Lighitng-1.0.1 Light to be Recognized Correctly by Hue Hub" sounds like it's possible)

In the article it's mentioned that the ZLL device has to be part of a HA network in order to transport the network key encrypted with the HA default trust center link key.

I've managed to join a Philips Hue bulb to my HA network by resetting it before. But the same didn't work for the Philips Hub (aka bridge).

The hub can be resettet fine but it won't scan and join my HA network.

So the big question is how can I join the Philips hue hub to my HA network?

Maybe the hub port 30000 on the bridge could be used to force the bridge to scan?

Two commands for hub port 30000 are  known to me:

- [Link,Touchlink] to scan and join ZLL devices

- [Link,Discover] opens the permit join flag for while. I discovered this command by trial and error ;)

best regards,

    Manual,

        Unfortunately the details of how to make the Hue Hub join a HA network is not publically known. The spec say that it must be possible by manufacturer specific means (required to pass the test spec), but these means have not been published.

    The ZStack-Lighting1.0.1 FAQ highlights a compatibility issue between the TI ZLL Light and Philips Hue Hub and gives details of how to fix this. The official fix is now include in the ZStack-Lighting-1.0.2 release (so please use this).

    However this issue is only visible when a TI ZLL Light is on the same network as the Hue Hub, and (unless the Hue Hub joins a HA network) this is only possible when the ZLight is programmed with the ZLL Master Key.

    Unlike HA (which has a public HA trust center Link Key) ZLL uses a secret Key programmed into all devices and used to encrypt/decrypt the random network security key. ZLL product manufacturers must apply for this secret ZLL Master Key after passing certification. TI ZLL application have been certified but do not contain the ZLL Master Key for obvious reasons.

    For a demonstration of controlling ZLights via a SmartPhone or Cloud service we will soon be releasing a wiki which uses the TI ZLL Control Bridge Sample App to control the network of Lights.

    Regards, TC.
