Adding support for Moes/Tuya Smart Thermostat For Pilot Wire Heating (_TZE204_x9usygq1)

[loicbr]

I'm trying to add support for this device, sold on aliexpress under many brands (mine is https://www.aliexpress.com/item/1005007319412940.html?spm=a2g0o.order_list.order_list_main.53.21ef1802Z8FdNI ).

I've done the basic part :

const {} = require('zigbee-herdsman-converters/lib/modernExtend');
// Add the lines below
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 ota = require('zigbee-herdsman-converters/lib/ota');
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 tuya = require('zigbee-herdsman-converters/lib/tuya');
const logger = require('zigbee-herdsman-converters/lib/logger');

const definition = {

        ],
    },
    extend: [
        // A preferred new way of extending functionality.
    ],
};

module.exports = definition;

But I have problems with the last datapoints of raw type.

Datapoints 65 to 71 encode the mode programation for one day each, with 4 bits for each 30 minutes slices with the same values as in the runningStatus enum :

Lua: DPID :70
Lua: Type :0
Lua: len :24
Lua: Value : 444444444444114144444444444444444411111111114444

Datapoint 104 is used to light of the device status leds during the night period :

Lua: DPID :114
Lua: Type :0
Lua: len :5
Lua: Value : 004B056401

The first 2 bytes give the starting time in the form of numbers of minutes since 00:00
Next 2 bytes give the ending time.
Last byte is 1 when this behavior is enabled or 0 when not.

Any help on this is welcomed.
Thanks everyone in advance.

I thought the best place to implement that support was in a converter, so I copied tuya.valueConverter.raw (I want of course to modify it later) :

const myValueConverterBasic = {
    raw: () => {
        return {to: (v) => v, from: (v) => v};
    },
};

and put it in the tuyaDatapoints array :

 [65, 'weekProgram1', myValueConverterBasic.raw],

But when I try to write a new value, I get the following error :

[2024-10-14 22:13:49] error:    z2m: Publish 'set' 'weekProgram1' to '0xa4c1385ec10db54c' failed: 'Error: No datapoint defined for 'weekProgram1''
[2024-10-14 22:13:49] debug:    z2m: Error: No datapoint defined for 'weekProgram1'
    at Object.convertSet (/app/node_modules/zigbee-herdsman-converters/src/lib/tuya.ts:1352:27)

Hello,

I'm working on this module, if you want to take a look :
