Need help adding support for new devices.

Hi. I try to add new device (ikea tradfri spot).

I think the addons runs well in webthings:

I see traces at webthings start:

2019-12-17 22:56:53.279 WARN   : manifest.json did not exist for add-on zigbee2mqtt-adapter

When I try to add devices in webthings, I see an MQTT request to list devices:

zigbee2mqtt/bridge/config/devices/get (null)
zigbee2mqtt/bridge/config/devices [{"ieeeAddr":"0x00124b0019367fa1","type":"Coordinator","netw
...

the answer does contains some bulbs that I am trying to add:

    {
      "ieeeAddr": "0x14b457fffe487b91",
      "type": "Router",
      "networkAddress": 64343,
      "model": "LED1537R6",
      "friendly_name": "lum/salon/n10",
      "manufacturerID": 4476,
      "manufacturerName": "IKEA of Sweden",
      "powerSource": "Mains (single phase)",
      "modelID": "TRADFRI bulb GU10 WS 400lm",
      "hardwareVersion": 1,
      "softwareBuildID": "2.0.022",
      "dateCode": "20190308",
      "lastSeen": null
    }

(note: device needs to have / in its friend_name because that makes my node red flows way easier to maintain, but is this compatible with

zigbee2mqtt-adapter/zigbee2mqtt-adapter.js

Line 71 in 2de28e5

this.client.subscribe(`${this.config.prefix}/+`);

?)
So I added the following in devices.js:

  'LED1537R6': {
    name: 'LED1537R6',
    '@type': ['Light', 'OnOffSwitch'],
    properties: {
      state: {
        '@type': 'OnOffProperty',
        type: 'boolean',
        fromMqtt: v => v === 'ON',
        toMqtt: v => (v ? 'ON' : 'OFF'),
      },
      brightness: {
        '@type': 'BrightnessProperty',
        type: 'number',
        minimum: 0,
        maximum: 255
      },
      color_temp: {
        type: 'integer',
        minimum: 0,
        maximum: 500,
      },
      linkquality: {
        type: 'integer',
        readOnly: true,
      },
    },
  },

but when I try to add device, the bulbs are not found:

2019-12-17 22:57:22.100 INFO   : About to call startPairing on ZigbeeMqttAdapter
2019-12-17 22:57:30.131 INFO   : Opened a new things socket
2019-12-17 22:58:22.107 INFO   : Pairing timeout
2019-12-17 22:58:22.112 ERROR  : Thing was not added
2019-12-17 22:58:22.114 ERROR  : addNewThing cancelled

Did I use the wrong name? Am I forced to factory request all my devicesand repair them from WebThings ?
I also tryed with TRADFRI bulb GU10 WS 400lm as name. I don't have supported devices to test withthem.

I added some trace before line 115 there:

zigbee2mqtt-adapter/zigbee2mqtt-adapter.js

Lines 112 to 116 in f4ff4c0

    
           addDevice(info) { 
        
             const description = Devices[info.modelId]; 
        
             if (!description) { 
        
               return; 
        
             }

and it seemd that Z2M send modelID when 'modelId` is expected.:

2019-12-18 00:13:55.476 ERROR  : zigbee2mqtt: Ignoring unkown device  {

2019-12-18 00:13:55.484 ERROR  : zigbee2mqtt: }

Ok, replacing modelId with modelID line 113 fixed it !

I will add the bulb to the devices list

	addDevice(info) {
	const description = Devices[info.modelId];
	if (!description) {
	return;
	}
