SimpleLogo auto change logo not working

sdetweil

@RoadRunnr1469 ok, looking thru the code and doc

Refresh/refetch image file between interval. Only use this if your image url return different image after some interval of time, even the fileUrl is not changed.

the code adds a time to the end of the fileurl to force a unique value. You could do this if the URl to the file stayed the same, but the actual file was different (something overwrote the file since last time)

so, they planned on the something changing the actual logo file contents

        var imgsrc = self.config.fileUrl;
            this.interval = setInterval(function() {   // < --- start a recurring timer
                img = document.querySelector(".simple-logo__container img[src*='" + imgsrc + "']");
                imgsrc = self.config.fileUrl;
                if(!imgsrc.includes("?"))
                        imgsrc += '?' + Date.now();  // < ---
                else
                        imgsrc += '&' + Date.now();  // < -----
                img.setAttribute('src', imgsrc);
            }, this.config.refreshInterval);  // < ---  refresh time
        }

the code also allows some other module to send it a message to change the logo url

I don’t understand why people have to be so confrontational and un helpful.

we are not being ‘un helpful’, the design of the mirror app is to INTENTIONALLY keep people from having to change the module file for different options…

so, when we see someone going down that path, we want to get them back on the design
I can look at the module code from github, I can’t see what you did locally. (in general)
makes it harder to help, and changes made get wiped out if there is a module update…
(that tends to make people upset when their stuff is lost!)

but your and my initial understanding of what was supposed to happen (as I didn’t know anything about this module), is wrong… update the cycle time but keep the same exact image and nothing will change.
you can prove this with 2 logo files.

start with one, and then copy the other over the 1st while the module is working.

we are all volunteers here…

Module: MMM-SimpleLogo

The MMM-SimpleLogo module is third party modules of the MagicMirror. This module simply displays logo.

Using the module

To use this module, add it to the modules array in the config/config.js file:

modules: [
    {
        module: 'MMM-SimpleLogo',
        position: 'top_left',    // This can be any of the regions.
        config: {
            // The config property is optional.
            // See 'Configuration options' for more information.
        }
    }
]

Configuration options

The following properties can be configured:

Option	Description
`fileUrl`	File url. Possible values: Logo link form internet or path to your local files relative to MagicMirror directory Default value: 'modules/MMM-SimpleLogo/public/logo.png'
`width`	Set width of your logo, height is auto. Possible values: `'300px'` or `'50%'` Default value: `'200px'`
`position`	Horizontal position on current container Possible values: `left`, `center`, or `right` Default value: `left`
`refreshInterval`	Refresh/refetch image file between interval. Only use this if your image url return different image after some interval of time, even the `fileUrl` is not changed. See this case #2, awesome project by @ElYoM Possible values: `1000`, `2000`, or `10000` Default value: `0` (disabled)
`text`	Text above the image. Possible values: Any text Default value: `Simple Logo`

Notification Events

The MMM-SimpleLogo module supports the notification event SIMPLE_LOGO_UPDATE which allows the configuration to be dynamically modified. As an example, the MMM-OnScreenMenu module might be used to dynamic adjust the fileURL parameter as follows:

{
    module: "MMM-OnScreenMenu",
    position: "top_left",
    config: {
        menuItems: {
            notify1: {
                title: "Show Cat",
                notification: "SIMPLE_LOGO_UPDATE",
                payload: {
                    fileUrl: "cat.jpg",
                    width: "750px"
                }
            },
            notify2: {
                title: "Show Dog",
                notification: "SIMPLE_LOGO_UPDATE",
                payload: {
                    fileUrl: "dog.jpg",
                    width: "1050px"
                }
            }
        }
    }
}

@RoadRunnr1469 right. Some external module sends a message.

I didn’t look at that code

@sdetweil
Based on the section “Notification Events” I added a section as called out.
this isn’t letting me paste it in here, says it is spam.

@sdetweil

I added this to the config.js file

            {
            module: "MMM-OnScreenMenu",
                    position: "bottom_right",
                    config: {
                            menuItems: {
                            notify1: {
                                    title: "Patch",
                                    notification: "SIMPLE_LOGO_UPDATE",
                                    payload: {
                                            fileUrl: "modules/MMM-SimpleLogo/public/Amc.JPG",
                                            width: "200px"
                                            }

                                notify2: {
                                        title: "Support",
                                        notification: "SIMPLE_LOGO_UPDATE",
                                        payload: {
                                                fileUrl: "modules/MMM-SimpleLogo/public/RedSupport.jpg",
                                                width: "150px"
                                                }
                                        },

@RoadRunnr1469 I won’t be able to look at this til tomorrow or Sunday.

Open the developers window ctrl-shift-i select the console tab and scroll up to see any messages sent from the on screen module

sdetweil

@RoadRunnr1469 I installed the module, and modified one of mine to send the notification, and it worked as expected.

sdetweil

@RoadRunnr1469 and you installed the “MMM-OnScreenMenu” module too, right?

RoadRunnr1469

@sdetweil yes, and the on screen option works fine changes the logo as expected.
