Could you check if the issue is fixed with the following external converter:

• save this as file next to configuration.yaml as ext_converter.js
• add it to configuration.yaml:

external_converters:
  - ext_converter.js

• start z2m, check if issue is fixed

hi there, should I add the below lines in the ext_converters.js file.

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 legacy = require('zigbee-herdsman-converters/lib/legacy');
const extend = require('zigbee-herdsman-converters/lib/extend');
const ota = require('zigbee-herdsman-converters/lib/ota');
const tuya = require('zigbee-herdsman-converters/lib/tuya');
const utils = require('zigbee-herdsman-converters/lib/utils');
const globalStore = require('zigbee-herdsman-converters/lib/store');
const e = exposes.presets;
const ea = exposes.access;

const definition = {
zigbeeModel: ['LXN56-TS27LX1.2'],
model: 'LXN56-TS27LX1.2',
vendor: 'Nue / 3A',
description: 'Smart light relay - 2 gang',
extend: [onOff({endpoints: {left: 1, right: 2}})],
whiteLabel: [{vendor: 'Zemismart', model: 'ZW-EU-02'}],
};

module.exports = definition;

I try both methods with above lines and without above lines in the ext_converters.js file but no success.

What doesn't work?

What doesn't work?
After put in new external converters file( you suggest ) not exposed to on and off switch.
It's same like initially I had issue. It pair with zigbee2mqtt but said not supported.

Can you provide the debug log when starting z2m with this ext converter?

See this on how to enable debug logging.

hi there, mate I am sending you my zigbee2mqtt log file. I setup according to you what you suggest in previous reply. after log debug mode setting my zigbee2mqtt running on portainer fail to start and I do not have access through frontend. I get log file through portainer.
_zigbee2mqtt_logs.txt

Your configuration.yaml syntax is wrong, paste it in https://www.yamllint.com/ to find the error.

hi there, mate you are right, I fix the mapping error then restart zigbee2mqtt portainer and pair again my dual GPO, It pair with zigbee2mqtt but said not supported. when I try to switch on my wall GPO right switch then a message pop up on Zigbee2mqtt. see the pop up message picture I take in the attachment.

I am also sending you latest z2m debug log file attached.
_zigbee2mqtt_logs-3.txt
see in the log file in last time starting from 2024-02-23 09:15:01.

Hi there, any help regarding previous new device support I was asking for. Please

I've updated https://gist.github.com/Koenkk/559a9856e15f67223cf10dfea98b3ba0, can you try again?

hi there, mate I update my ext_converters.js file according to link you provided above but I do not get success to control the GPO. It's still paired but says not supported. sending you latest log file attached with it.
_zigbee2mqtt_logs-4.txt. THE device id it "id":"0x00158d0006af743a having issues. check the log columns in the end.

Are you sure the contents of your external converter is correct?

hi there, I use the same file you sent me. See the ext_converters.js file attached.
ext_converter.txt
I change extension to .txt for sending purpose only. original file in .js extension I am unable to attach.

I've updated https://gist.github.com/Koenkk/559a9856e15f67223cf10dfea98b3ba0, can you try again with z2m 1.36.0?

hi there, mate I try above file you sent me early today but no success. same issue

hi there, mate any further solution for above mentioned issue ?

Updated https://gist.github.com/Koenkk/559a9856e15f67223cf10dfea98b3ba0 , could you try again?

I have submitted a working external converter for this device under #22887. Please use the External Definition under the new issue I have logged. Tested in 1.38.0 by removing my external converters to confirm it is not currently natively supported.

i use external convertor of link below
#22887 and ext_converter.js file below as well
my double GPO working fine. no issues. Thanks
