homebridge-hue: Warnings after Homebridge start (using default colour gamut for unknown light model)

Hi,

I can see the following warning after starting homebridge:

[01/11/2021, 06:24:24] [Homebridge-Hue] Philips hue: /lights/18: warning: using default colour gamut for unknown light model {"state":{"on":false,"bri":254,"hue":6805,"sat":188,"effect":"none","xy":[0.425,0.4027],"ct":308,"alert":"select","colormode":"ct","mode":"homeautomation","reachable":true},"swupdate":{"state":"notupdatable","lastinstall":"2020-05-11T12:50:31"},"type":"Extended color light","name":"Büro Decke","modelid":"371000002","manufacturername":"Paulmann Licht","productname":"Extended color light","capabilities":{"certified":false,"control":{"colorgamuttype":"other","ct":{"min":153,"max":370}},"streaming":{"renderer":false,"proxy":false}},"config":{"archetype":"classicbulb","function":"mixed","direction":"omnidirectional"},"uniqueid":"00:15:8d:00:04:4a:28:4a-01","swversion":"1400-0001"}

The lamp /lights/18 is a Paulmann Amaris lamp (controlled via Zigbee / Hue Bridge).

ph probe ( ph -H 192.168.0.50 -u "USER" probe -v /lights/18) gets a timeout on the color “red”, “green” and “blue”:

Colors are generally working but sometimes inaccurate via Apples Home App (HomeKit) and also via the Philips Hue App with this lamp. When I want to switch back from “colors” to “warm light”, the lamp sometimes doesn’t recognize it.

Thanks for your help!
