Need help with percentage control in my Tuya day/night curtain converter！！

[lccox]

What happened?

I wrote an external converter for the Tuya day/night curtains. The curtain device has the following DP points:
{
"1": "Day Curtain Control",
"2": "Day Curtain Percentage Control",
"3": "Day Curtain Percentage Status",
"101": "Night Curtain Percentage Control",
"102": "Night Curtain Percentage Status",
"109": "Night Curtain Control",
"120": "Night Curtain Motor Direction",
"121": "Day Curtain Motor Direction"
}

Using these DP points, I edited an external converter. It allows me to control the day and night curtains' open/close using DP 1 and 109, while DP 2 and 3 enable percentage control and feedback for the day curtain. However, I cannot achieve percentage control for the night curtain using DP 101, although I seem to be able to read the percentage using DP 102.

Here is the converter code I wrote:

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

const definition = {
    zigbeeModel: ['TS0601'],
    model: 'TS0601',
    vendor: '_TZE200_luexzx4j',
    description: 'Zhongling-DayNightCover-GM24TF/S-TYZ with dual cover support',
    fromZigbee: [tuya.fz.datapoints, legacy.fromZigbee.tuya_cover, fz.ignore_basic_report],
    toZigbee: [tuya.tz.datapoints, legacy.toZigbee.tuya_cover_control, legacy.toZigbee.tuya_cover_options],
    exposes: [
        e.cover_position().withEndpoint('cover_a').setAccess('position', ea.STATE_SET),
        e.cover_position().withEndpoint('cover_b').setAccess('position', ea.STATE_SET),
    ],
    meta: {
        multiEndpoint: true,
        tuyaDatapoints: [
            // Cover A
            [1, 'state_cover_a', tuya.valueConverterBasic.lookup({'CONTINUE': tuya.enum(3), 'CLOSE': tuya.enum(1), 'STOP': tuya.enum(2), 'OPEN': tuya.enum(0)})],
            [2, 'position_cover_a', tuya.valueConverter.coverPositionInverted],
            [3, 'position_cover_a_raw', tuya.valueConverter.raw],
            // Cover B
            [109, 'state_cover_b', tuya.valueConverterBasic.lookup({'CONTINUE': tuya.enum(3), 'CLOSE': tuya.enum(1), 'STOP': tuya.enum(2), 'OPEN': tuya.enum(0)})],
            [101, 'position_cover_b', tuya.valueConverter.coverPositionInverted], // Fix for percentage control logic
            [102, 'position_cover_b_raw', tuya.valueConverter.raw],
        ],
    },
    endpoint: (device) => {
        return {
            cover_a: 1,
            cover_b: 1, // DP is used for distinguishing features, no need for separate endpoints
        };
    },
    configure: async (device, coordinatorEndpoint, logger) => {
        await tuya.configureMagicPacket(device, logger);
    },
};

module.exports = definition;

I would appreciate any insights or solutions to enable percentage control for the night curtain using DP 101.

What did you expect to happen?

I need assistance in completing the percentage control for the night curtain to improve the external converter, allowing the device to function correctly. Thank you!!!!!!
