Error: This device don't config miot spec on Xiaomi Mi Air Purifier 2H

[fuomag9]

When I try to run the following code I get UnhandledPromiseRejectionWarning: Error: This device don't config miot spec on a Xiaomi Mi Air Purifier 2H. The device works fine and can be correctly read with the miio library

const mihome = require('node-mihome');
mihome.miioProtocol.init();
const options = { country: 'en' };

async function f() {
    const device = mihome.device({
        id: '▀▀▀▀', // required, device id
        model: 'zhimi.airpurifier.mc2', // required, device model

        address: '▀▀▀▀', // miio-device option, local ip address
        token: '▀▀▀▀▀', // miio-device option, device token
        refresh: 30000, // miio-device option, device properties refresh interval in ms

        parent: '', // aqara-device option, gateway SID for aqara-protocol compatible device
    });
    device.on('properties', (data) => {
        console.log(data);
    });
    await device.setPower(true); // call the method
    await device.init(); // connect to device and poll for properties
    device.destroy();
}

f()

Ok, i dont know your skills, but eventually you can extrakt working code from my skript here. This worked fine with the 3H. https://github.com/Pittini/iobroker-nodemihome/blob/main/old/Airpurifier3H-V0.1.6.js

try device.init() before device.setPower(true)

Still not working unfortunately, plus per https://github.com/maxinminax/node-mihome/blob/master/README.md device.init() is called after device.setPower(true), so one of those is wrong
