Module is flashing (reloading?)

[tomkenner]

The module flashes at different intervals. Sometimes every 3 seconds, then not for longer...

I checked it: it's every time when he fetches http://myip/modules/MMM-WienerLinien//templates/MMM-WienerLinien.njk?s=1638776447287

But I don't know, why he sometimes fetches this URL so often.

[tomkenner]

The socketNotificationReceived method is called very often. There the DOM is updated (which causes the flashing).

I inserted a console.log(Date.now());

This is the output for 1 given Station ['1293'] - time in ms:

MMM-WienerLinien.js:189 1638900459813

@tomkenner could you share your config of the module? Did you maybe override the defaults?

[tomkenner]

Here is the config of the module:

           {
                    module: 'MMM-WienerLinien',
                    position: 'top_left',
                    config: {
                            stations: ['1293','2983'],
                            max: 5,
                            updateInterval: 60000,
                            rotateInterval: 5000,
                    }
            },

@tomkenner using that config the method socketNotificationReceived was correctly called every 60sec like specified.

The rotate interval of every 5 seconds was the only thing causing the flashing.

Can you maybe give some more details about your setup?

Magic Mirror version?

node version?

module version?

[tomkenner]

As you can see above (timestamps from log) the flashing occurs more often than every 5 seconds. At the beginning it worked fine. After some days it began with the flashing-problem.

Magic Mirror version: 2.17.1

node v12.22.5

module version: 2.0.1
