Thanks for looking into this, could you make a PR?

My current version for converter is:

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 tuya = require('zigbee-herdsman-converters/lib/tuya');

const definition = {
	fingerprint: [{modelID: 'TS0601', manufacturerName: '_TZE200_yojqa8xn'}],

            [16, 'silence', tuya.valueConverter.raw],
        ],
    },
};

module.exports = definition;

BUT, I have an issue f.e. with DP 13 'alarm_switch'.
When trying to send command , got in log:

debug 2022-12-01 21:45:53: Received MQTT message on 'zigbee2mqtt/sGas Boiler/set' with data '{"alarm_switch":true}'
error 2022-12-01 21:45:53: No converter available for 'alarm_switch' (true)

Tried to find where (in code) this error generated, but can't find.
Looks I can't use any other key not included in tuya.tuyaTz.datapoints.key !?!?!

I've created the pr, please check the comments: Koenkk/zigbee-herdsman-converters#5065
