Reading input and temperature in a script

Hi and welcome to the forum.

What kind of script do ask for? Shelly-scripting or script for a automation system like ioBroker?

Here's a quick example

Shelly.call(
    "switch.getStatus",
    { id: 0 },
    function (response) {
        let status = response.output ? "on" : "off";
        let temp = JSON.stringify(Math.round(response.temperature.tC));
        print("Output is " + status);
        print("Device temperature is " + temp + " degree celsius");
    },
    null
);

just for clarification: it is mandatory to have some basic javscript skills in order to work with Shelly mJS, all functions are documented here:

Hello!

If you want to read the temperature from the DS18b20 sensor on the Shelly AddOn, you should call something like this:

Shelly.call(
    "temperature.getStatus",
    { id: 100 },
    function (response) {  
        MQTT.publish("hello/world", JSON.stringify(response), 0, false);
    },
    null
);

Could you show an example of reading the temp/hunifity, calculate the dew point and activate the power outlet if dew point is below x degrees?
