Does anyone know how to make the iFrame module refresh periodically?

@PeppaPigKilla
Sorry the forum seems to be overloaded. I put this in my code and still no refreshing. I believe the problem is my iFrame does not have a specified name. I am only able to input the scr=“URL”. Not sure where to put iframe name = “name”. When generating an iFrame from google sheets it does not specify a name either.

I tried it and cant get it to work either. best reaching out to the author,

@PeppaPigKilla the code that was added by you is after the return, so the code will never be reached.

I suggest an interval which calls updateDom, which will be created after the DOM_OBJECTS_CREATED broadcast

Thanks for the suggestion. I wouldn’t know where to start with that though. I tried this module which did not work refresh for me either.

@cnelso24 the problem is probably that there isnt a change detected when updating the dom, try to add a timestamp attribute to the iframe.

I have found a fix for this module which I posted here:

@kevsfastz is it possible to show simple html content and update periodically?

@fox
The simple answer is yes it is possible. What is your goal specifically?

Many thanks, I have bee looking for a way to do this for some time. I loaded iFrameReload with the following url. It will load, but not update. Any suggestions as to what I am missing?

url: “http://tides.tidegraph.com/api/tidegraph.php?bg=black&scale=.8&station=Old Frenchtown Wharf, Elk River, Maryland”,

Many thanks

As mentioned above, I have provided a fix or adjustment by adjusting the MMM-IframeReload.js below:

My mistake, I thought this was updated in the .git. I added the timestamp as you suggested (iframe.src = this.config.url + new Date().getTime();). The url does update now, but since the url displays the tides at a location embedded in the url, it looks like the timestamp is appended to the location. With this added, it is not a valid location and the tides don’t display.

Again, many thanks for your help.

I see what you mean with the URL, any variables you add at the end even a ? will result in displaying all zeros on the output. You can get around this by using a site such asTHIS to refresh this URL for you instead of using iFrame to call a refresh. Of course all these sites will have advertisments which you do not want displayed on your mirror… so what you COULD do is reposition the iframe so the advertisment is hidden in one of the top corners. For example you can add margins with negative values to the iframe style:

iframe.style = “border:0;margin-bottom:-110px;margin-left:-10px;;width:500px;height:450px;filter:invert(100%);”

Of course this is not the best nor the most clean solution… maybe someone else has some ideas?

I have another raspberry who gets temperatures with one-wire-sensors.
This i provide in a simple homepage:

    <div>
      <div>
    <h2>...</h2>
	<p><b>Temperaturen:</b></p>
    <p>Luft:............ -3.5°</p>
	<p>Dach:........... -2.5°</p>
	<p>Pool: ............3.5°</p>
	<p><b>Status: </b></p>
	<p>Pumpe:........... <b>Aus</b></p>
    <p>Solarheizung:...<b>Aus</b></p>
    <br />
	<p><b>Meta: </b></p>
    <p>System:...........Linux 4.1.19+ armv6l</p>
	<p>CPU Temp:....14.260°</p>
	<p>Sensors...........3 x DS18B20 @ 5V </p>
    <p>Last Update:......Mon 13-02-2017, 19:40:05 Uhr</p>
	</div>
	<p>....</p>
     
    </div>

how to show this, or parts of it?

edit:(the html header will not be shown in this forum framework :walking:

@fox

This depends on the output of your other Pi. If you already have this output displayed in say HTML format ( I assume that’s what you mean when you say simple homepage?) you can easily place this in iFrame via local URL. The best way would be to create its own page so you can control the output, then you can use CSS styles to adjust colors, size, placement etc.

Thank you for your answer. I tried of course, but I got only a white line on the screen.

@fox

Can you show a sample of your code? I assume the URL is working fine in a web browser?

fox

@kevsfastz
Above is a sample of the code(the weird forum framework removed the headd of the html )
Yes it is working very fine in the web browser

Does this help you?

Thank you in advance !
