Garage Door Detectors

morozgrafix

@istepgueu as far as I understand MMM-Buttons only sends notifications when button is triggered (long or short press). Your sensor is acting as a long button press and you got it working so far. What I think you need is a custom module to display status of your garage door(s) that is capable of accepting notification from MMM-buttons and then changing message displayed (or image) on the MM. One thing to keep in mind (as far as i know) is that MMM-buttons assumes that no buttons are pressed when MM starts, in your case you may need some additional logic to account for times when MM starts when your garage door is opened. @Jopyth is the original creator of MMM-buttons and may have some ideas on how to deal with that.

@morozgrafix Ok I understand the principle. I will try to look at this but I do not have enough skills.

On the way to create a module “MMM-doors-sensor”

istepgueu

I have create a MMM-door-sensor ‘module’
https://github.com/istepgueu/MMM-door-sensor

The module receive SHOW_ALERT and HIDE_ALERT from MMM-Buttons but I do not know how to show such or such text (Toto/Tata) according to the received notification.

Any help is welcome.
Thank you very much ;)

@istepgueu you need a getDom function where you render your images.

then in the notification received save the state in variables then call updateDom.

in getDom you render the images based on the state

Thank you for the help !
I understand the principle but not knowing javascript, I have a little trouble with the variables.

This is my (not working) code :

/* global Module */

/* Magic Mirror
 * Module: MMM-door-sensor
 *
 * By iStepgueu http://www.twitter.com/istepgueu
 * MIT Licensed.
 */

Module.register("MMM-door-sensor",{

	// Default module config.
	defaults: {
		text: "Hello World!"
	},


	// Define start sequence.
	start: function() {
		Log.info("Starting module: " + this.name);

	},



	notificationReceived: function(notification, payload, sender) {
		if (sender) {
			Log.log(this.name + " received a module notification: " + notification + " from sender: " + sender.name);
			if (notification === "REMOTE_ACTION") {
				this.sendSocketNotification(notification, payload);	

				var door_state = "close.png";			
	
				this.updateDom();				
			
			}
		} else { 
			if (notification === "DOM_OBJECTS_CREATED") {
				this.sendSocketNotification("REQUEST_DEFAULT_SETTINGS");
			
				var door_state = "open.png";


				this.updateDom();


			}
		}
		
		},


		getDom: function() {

		var wrapper = document.createElement("div");
		return door_state;
		wrapper.innerHTML = '<img src=" + door_state + " />';
		return wrapper;
	}



});

Module.register("MMM-door-sensor",{

	// Default module config.
	defaults: {
		text: "Hello World!"
	},

	// Define start sequence.
	start: function() {
		Log.info("Starting module: " + this.name);
	},

	notificationReceived: function(notification, payload, sender) {
		if (sender) {
			Log.log(this.name + " received a module notification: " + notification + " from sender: " + sender.name);
			if (notification === "DOOR_STATE") {

				this.door_state = payload;			
	
				this.updateDom();				
			
			}
		} 
		
	},


	getDom: function() {

		var wrapper = document.createElement("div");
if(this.door_state){
		wrapper.innerHTML = '<img src=" + this.door_state + " />';
} else {
		wrapper.innerHTML = 'No door state present.';
}
		return wrapper;
	}
});

config mmm-button

{
                pin: 24,
                name: "power",
                longPress: {
                    title: "Power off",
                    message: "Keep pressed for 3 seconds to shut down",
                    imageFA: "power-off",
                    notification: "DOOR_STATE",
                    payload: "close.png"
                },
                shortPress: undefined
            }

you would therefore need a button released to send open.png

@strawberry-3.141 Thank you !! It’s working :-)

I like the MMM-door-sensor module, and I see that it uses notificationReceived to change the icon, but how do you send a notification to the module? I have tried this.sendNotification but I cannot seem to get it to work…
