Mqttthing UI Hoobs settings?
**Description**
I just cant "migrate" my simple settings to the Hoobs UI ???
Would really like to get this filled out through the UI so updates are valid HOOBS 4 etc....

Plugin: Mqttthing
1.1.25 published 12/27/2020
Homebridge plugin supporting various services over MQTT

Homebridge setup: Temperaturesensor and one "FAKE" Thermostat to get the temperature visible in Google Home

> {
            "accessory": "mqttthing",
            "type": "thermostat",
            "name": "Temperatur i Haven (thermostat)",
            "url": "mqtt://192.168.0.12:1883",
            "username": "USER",
            "password": "PASSWORD",
            "topics": {
                "getCurrentTemperature": {
                    "topic": "tele/Sonoff_TH16_1/SENSOR",
                    "apply": "return JSON.parse(message)[\"DS18B20\"].Temperature;"
                }
            }
        },
        {
            "accessory": "mqttthing",
            "type": "thermostat",
            "name": "Temperatur i Garagen (thermostat)",
            "url": "mqtt://192.168.0.12:1883",
            "username": "USER",
            "password": "PASSWORD",
            "topics": {
                "getCurrentTemperature": {
                    "topic": "tele/Sonoff_TH16_2/SENSOR",
                    "apply": "return JSON.parse(message)[\"DS18B20\"].Temperature;"
                }
            }
        },

The UI is very very long, and hard to get a overview

These are the two lines I cant place:

            "topics": {
                "getCurrentTemperature": {
                    "topic": "tele/Sonoff_TH16_2/SENSOR",
                    "apply": "return JSON.parse(message)[\"DS18B20\"].Temperature;"
