Philips Hue Binding not connecting when I press the button on the bridge

Hi! I’m new to openHAB and installed Openhabian version 4.0.2 on a Raspberry Pi 3. This isn’t my first installation as I had used it a while ago just to test it out (Notably, I didn’t run into this problem the first time). I followed the instructions outlined in the Adding Things - Simple page of the Getting started guide to add my Hue Bridge.

After installing the binding, it successfully discovers the Hue Bridge and I can add it as a thing. However, the bridge thing gives the error The application key is not authorized. I tried deleting the application key (It seems to have just filled one in by default, and when I had tried openHAB out the first time, I remember it just being blank) which then gives the error Not authenticated. Press pairing button on the Hue Bridge or set a valid application key in configuration.. Pressing said button, as the tutorial said to do, doesn’t seem to do anything. After a while, a new application key appeared automatically, and the error changed back to The application key is not authorized.

In the logs (I’m viewing them using frontail) I get a warning stating 2023-08-21 05:13:46.946 [WARN ] [.internal.handler.Clip2BridgeHandler] - Cannot update bridge thing 'hue:bridge-api2:001788fffe2c9979' from legacy since handler already initialized. after deleting the application key. When pressing the button on the bridge, nothing changes in the logs. Other than the warning, I’m just getting INFO messages whenever the error message changes.

I’ve also checked, and the IP Address for the bridge does match what it says in the Hue app.

Here’s the code for the Bridge:

UID: hue:bridge-api2:001788fffe2c9979

If you had used a ‘legacy’ API v1 Hue Bridge thing in the past, then when you create a new API v2 Bridge thing now, it will copy over the key from the legacy thing. But obviously if the legacy key was bad then it will still be bad.

You contradicted yourself in the same paragraph; “doesn’t seem to do anything” then “After a while, a new application key appeared”.

Hmm. That is unexpected. Can you please try the following command (substitute ‘your-application-key’ and ‘bridge-ip-address’)…

curl --insecure -H "hue-application-key: your-application-key" -X GET "https://bridge-ip-address/clip/v2/resource/light" -v

I haven’t ever used the legacy bridge - I was thinking the bridge could still be connected to the old installation on the Hue side of things but I tried factory resetting the hue bridge and reconnecting the bridge thing but I’m still getting the same problem

Ah yeah, that’s my bad.

After running the command, I get

Note: Unnecessary use of -X or --request, GET is already inferred.

* ALPN: offers h2,http/1.1
* (304) (OUT), TLS handshake, Client hello (1):
* SSL connection timeout
* Closing connection 0
curl: (28) SSL connection timeout

If you had an"old’ installation then it is a legacy installation. If you create a new API v2 thing with this version of the binding, then it will look for any old/legacy thing and copy the key.

Umm. You must have run it wrong. Can you quote your exact command line? Are you running it from Linux or Windows?

Ah sorry - I run it from the terminal on my Mac (which uses unix like linux does), as running it in openHAB from SSH gave me the error Command not found: curl

The exact quote from the command line is

benmoon@Bens-MBP ~ % curl --insecure -H "hue-application-key: mjVOswWqYbihipoWXr3YG8nmYHX8yjQaeYuGpaTX" -X GET "" -v       

and then the result is exactly what I sent before

Try single quotes rather than double quotes. Also check the IP address of your Hue bridge – without any port number.

Oh I see - I used the openhab IP address instead of the hue one. After running the command this time, I get

hue-application-key in the output does match the application key set in openHAB

The curl response is HTTP 200 OK and the Hue bridge server returned content has "errors":[] … which means your application key is perfectly Ok. So you just need to edit your Hue bridge thing to have the exact same key.

As I’ve said in the last post, the application key does match exactly. I just double checked to make sure (I copied from the output directly to the thing) and I’m still getting the same error.

Edit: Actually nevermind… not sure what did it but I tried clicking save a few times and after a while it appeared as online. Thanks for your help!

Is it (wrongly) wrapped it in quote marks? And/or does it have excess whitespace at start or end?

This worked for me. click Save in the GUI.
