Bonjour la commu!
En quête d’ampoule RGBW en GU10 je suis tombé sur la Lexman vendu pour 460 lumens qui semble correct (à voir)
Elle fonctionne en zigbee (compatible enki). Evidement elle n’est pas encore supporté dans Z2M. 
Du coup j’essais de l’ajouter [Support new devices | Zigbee2MQTT]
D’autre ampoule lexman sont supportées:
https://github.com/Koenkk/zigbee-herdsman-converters/blob/master/devices/adeo.js
Je m’en inspire donc pour faire le converters:
const exposes = require('zigbee-herdsman-converters/lib/exposes');
const fz = {...require('zigbee-herdsman-converters/converters/fromZigbee'), legacy: require('zigbee-herdsman-converters/lib/legacy').fromZigbee};
const reporting = require('zigbee-herdsman-converters/lib/reporting');
const extend = require('zigbee-herdsman-converters/lib/extend');
const tz = require('zigbee-herdsman-converters/converters/toZigbee');
const e = exposes.presets;
const definition = {
zigbeeModel: ['ZBEK-4'], // The model ID from: Device with modelID 'lumi.sens' is not supported.
model: 'IM-CDZDGAAA0005KA8MAN', // Vendor model number, look on the device for a model number
vendor: 'Lexman', // Vendor of the device (only used for documentation and startup logging)
description: 'RGBTW GU10 Bulb', // Description of the device, copy from vendor site. (only used for documentation and startup logging)
fromZigbee: [], // We will add this later
toZigbee: [], // Should be empty, unless device can be controlled (e.g. lights, switches).
extend: extend.light_onoff_brightness_colortemp_color(),
};
module.exports = definition;
Je redémarre Z2M et j’ajoute l’ampoule qui du coup est bien reconnue.

Seulement ca ne fonctionne pas pour toute action que je fait j’ai une erreur
No converter available for state ("ON")
Et là mes compétences bug 
Avez-vous des pistes, des solutions à me soumettre svp? 
Merci d’avance
