Comments

Im kind of stuck with my first unsupported device but not sure if it is code or lack of compatibility between my Zigbee dimmer and the Led light. I have the Namron Zigbee Tunable White Dimmer connected to a SG Junistar soft TW leddim. https://www.sg-as.com/en-gb/products/junistar-soft-tw

The light turns on/off and dims but the led light does not respond to color temperature changes.

const fz = require('zigbee-herdsman-converters/converters/fromZigbee');
const tz = require('zigbee-herdsman-converters/converters/toZigbee');
const exposes = require('zigbee-herdsman-converters/lib/exposes');
const reporting = require('zigbee-herdsman-converters/lib/reporting');
const extend = require('zigbee-herdsman-converters/lib/extend');
const e = exposes.presets;
const ea = exposes.access;

const definition = {
    zigbeeModel: ['4512739'],
    model: '4512739',
    vendor: 'Namron',
    description: 'Zigbee Tunable White Dimmer 400W',
    extend: extend.light_onoff_brightness_colortemp({colorTempRange: [160, 450]}),

};

module.exports = definition;

Thanks!

It seems likely that the Namron Zigbee TW dimmer is not compatible with SG TW LEDDim. I tested with an SG Disc lamp and the phase cut dimming worked, but I was unable to control the white temperature. Its possible that this dimmer only works with Namron's own LED strip driver and nothing else! There is no documentation on compatibility and no technical support.

I could not control the colour temperature using the physical switch input either, so I don't think this is a problem on the Zigbee side.

This issue is the only relevant discussion I could find, so I'm adding this comment in case it helps other people.

Most probably Namron and SG have developed each their own proprietary way to communicate and set white temperature between dimmer and lamp.
