  • Sensor arcón congelador ZT08 e integración en Home Assistant

    Hace unas semanas vi un termómetro zigbee con una sonda externa que me podia ir bien para el arcón congelador que tengo , el enlace de Aliexpres es este

    Lo elegí porque el que tenia antes a partir de -20ºC tenia problemas y no daba lectura , el mínimo teórico de este dispositivo son -40ºC

    Se puede colocar de diferentes maneras , desde magnética , adhesiva y con ventosa , al final me decante por la adhesiva en la tapa de las baterías.

    Va alimentado por tres pilas AAA

    Al alimentarlo ya nos muestra la temperatura local , la de las sonda , la hora y el nivel de bateria , pero las temperaturas en grados Fahrenheit

    El siguiente paso es integrarlo en zigbee2mqtt , la información de este dispositivo será la siguiente.

    Nada mas emparejarlo nos dice que no esta soportado , y nos devuelve este identificador “_TZE284_hodyryli“

    Para disponer de el tendremos que usar un converter , aquí encontre uno que funcionaba , el código seria el siguiente :

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

const fzLocal = {
    tuya_weather_station: {
        cluster: 'manuSpecificTuya',
        type: ['commandDataReport', 'commandActiveStatusReport', 'commandMcuSyncTime'],
        convert: (model, msg, publish, options, meta) => {
            const result = {};
            
            // Time synchro
            if (msg.type === 'commandMcuSyncTime') {
                (async () => {
                    try {
                        const endpoint = msg.endpoint;
                        const now = new Date();
                        
                        const utcTime = Math.round(now.getTime() / 1000);
                        const localTime = utcTime - (now.getTimezoneOffset() * 60);
                        
                        const utcArray = [
                            (utcTime >> 24) & 0xFF,
                            (utcTime >> 16) & 0xFF,
                            (utcTime >> 8) & 0xFF,
                            utcTime & 0xFF,
                        ];
                        
                        const localArray = [
                            (localTime >> 24) & 0xFF,
                            (localTime >> 16) & 0xFF,
                            (localTime >> 8) & 0xFF,
                            localTime & 0xFF,
                        ];
                        
                        const payload = {
                            payloadSize: 8,
                            payload: [...utcArray, ...localArray],

module.exports = definition;

    Crearemos el fichero TS0601.js y copiamos el código en el

    paramos el docker

    en configuration.yaml añadimos el fichero del converter

    groups: {}
external_converters:
  - TS0601.js
  - TS0202.js

    Arrancamos el docker y ya nos aparece el nuevo dispositivo

    Ya podemos ver como empieza a exponer los datos

    Físicamente una vez colocado quedaria así , con los grados en Fahrenheit 🙁

    Y después de reiniciar veremos como va guardando los diferentes valores

    Y con esto y un bizcocho …………

    BONUS : Me tocaba bastante los webs ver los grados en Fahrenheit por lo que mire a ver como ponerlos en Celsius

    Para ello cambiaremos el código del converter por este

    },
};

module.exports = definition;
