Hue Go with colorcapabilities of 0 won't start colorloop (internal error 951)

Hi,

I’m just getting started with the REST API. I have a Hue Go as follows:

{
  "colorcapabilities": 0,
  "ctmax": 65279,
  "ctmin": 0,
  "etag": "7918ab69a1190c6cfbedbc61c2361571",
  "hascolor": true,
  "lastannounced": null,
  "lastseen": "2021-08-19T12:22Z",
  "manufacturername": "Philips",
  "modelid": "LCT026",
  "name": "Hue Go",
  "state": {
    "alert": "none",
    "bri": 254,
    "colormode": "hs",
    "ct": 500,
    "effect": "none",
    "hue": 7998,
    "on": true,
    "reachable": true,
    "sat": 254,
    "xy": [
      0.5285,
      0.4307
    ]
  },
  "swversion": "1.88.1",
  "type": "Extended color light",
  "uniqueid": "00:17:88:01:08:5b:5c:e2-0b"
}

When I try to set it to a colorloop, with this:

{"on":true,"bri":255,"hue":8000,"effect":"colorloop","colorloopspeed":"10"}

The response is this:

[
  {
    "success": {
      "/lights/25/state/on": true
    }
  },
  {
    "success": {
      "/lights/25/state/bri": 254
    }
  },
  {
    "success": {
      "/lights/25/state/hue": 8000
    }
  },
  {
    "error": {
      "address": "/lights/25/state/effect",
      "description": "Internal error, 951",
      "type": 901
    }
  }
]

I noticed that colorcapabilities is set to 0, whereas it’s a number for my other Hue bulbs. Is this the cause of the problem?

Thank you.

Got some advice on the Discord to read in the colour control cluster using the deCONZ UI, and that was enough to update the colour capabilities of the Go, and Colourloop works great now. Thanks Swoop.
