MMM-PIR-Sensor: "Welcome back" message

deWizard

Hi there,

I’m completely new to all of this but still want to give it a try.
I’ve intergrated the MMM-PIR-Sensor module to my MagicMirror and it’s working just fine.

The Issue I’m now facing is that I want to display a “Welcome back!” message when the monitor is reactivated. I’ve tried some things but none of them worked at all.

Anyone to help me out with that - it would be very appreciated. :)

I don’t have a PIR to test, but looking at the code, I’d suggest trying something like this:

You need a DOM element to show the message in. You can borrow it from the default module helloworld and modify it:

getDom: function() {
    var wrapper = document.createElement("div");
    wrapper.setAttribute("id", "welcome-message");
    wrapper.innerHTML = "";
    return wrapper;
}

And then, based on self.sendSocketNotification("USER_PRESENCE", true); in the node_helper.js you add
this to the MMM-PIR-Sensor.js :

socketNotificationReceived: function(notification, payload) {
    if (notification === "USER_PRESENCE"){
        this.sendNotification(notification, payload)
//  new:
        if (payload === true) {
        document.getElementById("welcome-message").innerHTML = "Welcome back!";
        setTimeout(() => {
            this.removeMessage();
        }, (1*60*1000); // = 60 seconds
    }
},
removeMessage: function(payload) {
    document.getElementById("welcome-message").innerHTML = "";
}

If you use it like this, the message is only shown for 1 * 60 * 1000 miliseconds = 60 seconds (set as desired) and then removed.

This is all untested but hopefully gives you some clues where to look and work on the code.
