Where should I report new / wrong device type detection?

I am using the Zigbee binding and finding out a few devices I own are supported perfectly or with slight differences. Where should I report such new working devices for the Zigbee binding, including small problems ?

For example the IKEA control outlet is detected as a dimmer, but can’t be used as such. When changing it category and type to Switch it behaves accordingly.

Another example, Gledopto GL-B-007Z is detected and works fine, including proper color controls.

Posting the issues here is fine. I tagged the thread as ZigBee to the developer and other helpful members know about it.

I personally do not use ZigBee but I use the Z-Wave binding from the same developer.

What version of OpenHAB are you running? Perhaps running a newer binding could resolve some of the issue you are experiencing.

Thank you, I am using 2.5.0M5 with manually installed Zigbee and Zwave bindings:

Since you are running Milestone 5, it should already have the latest binding without needing a manual install.
Generally people only use the manual installation to get support for additional devices or to correct other issues.
