Hot to get Input(100) values into a script

AJSG1969

Hello all, I am trying to run a script to restart a device every time its LED starts flashing. However, when restarting the device flashes the LED as well so the script needs to sleep.

I need the Script to react if LDR (photoresistor) is lower than 20% "Input (100)", set Output State to ON, and Flip Value after 10 seconds. However, it then needs to Sleep for 30 seconds. I cannot do the Sleep side in the Actions interface. I need to use a script.

I have a 2PM with a Plus Addon.

Input (100) is Analog and reports light value as a Percentage (range 0 to 100%)

I have tried using getComponentStatus("input:100") and I do get the right value:

Light Level { "id": 100, "percent": 44.5 }

So I can definitely pull that in. But how? The code below just looks for a Button Down event. This is part of a script written by a GIT contributor called nygma2004.

I have really tried but cannot find documentation on referencing that input being less than 20% to trigger the event

Code

function eventcallback(userdata) {
   print("Event called: ", JSON.stringify(userdata));
   // check if this a button press event
   if (userdata.info.event==="btn_down") {
     print("button down event");
     state = !state;
     if (state) {
       timercallback(null);
     } else {
       Timer.clear(timer_handle);
     }
   }
 }
 
 Shelly.addEventHandler(eventcallback, userdata);

Any help gratefully received.

Thanks,

Hello Andrew,

welcome to the forum.

"Shelly.call" is the function you need: https://shelly-api-docs.shelly.cloud/gen2/0.14/Scri…ures#shellycall

You can try this script to get the value from the analog input (eventually you have to change the "id" value):

Code

Shelly.call("Input.GetStatus",{ id:101 },
    function(result, err_code, err_message, user_data) {
        if (err_code === 0) {
            console.log("Temperature:", result['percent']);
            if (result['percent'] < 20.0) {
                // do something
            } else {
                // do something else
            }
        } else {
            console.log("Error:", err_message);
        }
    }
);

Thank you Nordlicht_2023,

Got the output to react to the light setting at 20%. I am now struggling with the timer function. I also had to change "function" to "function callback"

Code

Shelly.call("Input.GetStatus",{ id:100},
    function callback(result, err_code, err_message, user_data) {
        if (err_code === 0) {
            console.log("LightValue:", result['percent']);
            if (result['percent'] < 20.0) {
                print("light")
                Shelly.call("Switch.Set","{ id:0, on:true }",null,null);
                let timer_handle = Timer.set(2000,true,callback,null);
                Shelly.call("Switch.Set","{ id:0, on:false}",null,null);
            } else {
                print("dark")
                Shelly.call("Switch.Set","{ id:0, on:false}",null,null);
                let timer_handle = Timer.set(1000,true,callback,null);
             }
        } else {
            console.log("Error:", err_message);
        }
    }
);

You're welcome.

I think the function from shelly.call can't call from outside and is for the processing through shelly.call only.

Try to call a timer and a new function around shelly.call. So can the timer call the "lightcheck" function every 2 seconds:

Code

function lightcheck () {
    Shelly.call("Input.GetStatus",{ id:100},
        function (result, err_code, err_message, user_data) {
            if (err_code === 0) {
                console.log("LightValue:", result['percent']);
                if (result['percent'] < 20.0) {
                    print("light")
                    Shelly.call("Switch.Set","{ id:0, on:true }",null,null);
                } else {
                    print("dark")
                    Shelly.call("Switch.Set","{ id:0, on:false}",null,null);
                 }
            } else {
                console.log("Error:", err_message);
            }
        }
    );
};


let timer_handle = Timer.set(2000,true,lightcheck,null);

@Nordlicht_2023 Thats wrong.

You can always get your input values with print(Shelly.getComponentStatus('input',100));, No 'Shelly.call' is necessary for this.

@AJSG1969 Welcome,

What you are looking for are events, and normally your input 100 should also create events, so you can just use an event handler, and then filter for your input 100 events.

Put this line of code into a script and it will show you all the events within your Script Consol: Shelly.addEventHandler(function(data){print(data);});

I can provide you with a code example that demonstrates how to use this event. However, I would need the structure of your 'input:100' events, so please share a screenshot of some input:100 events with me.
