{
		module: 'MMM-iFrameReload',
		position: 'top_left',	// This can be any of the regions.
		config: {
			// See 'Configuration options' for more information.
				url: 'http://192.168.178.xx:xx/cgi-bin/CGIProxy.fcgi?cmd=snapPicture&usr=USER&pwd=PASS',
				width: '640px', // Optional. Default: 100%
				height: '360px', //Optional. Default: 100px
				refreshInterval: 10  //Optional. Default: 3600 = 1 hour
			}
		},

with this, the iframe is loaded, but not refreshed after 10 seconds, I do get the following every 10 seconds in the console - so I guess principially it works?:

attempting to update dom for iFrameReload  MMM-iFrameReload.js:52:3
/"this/" module is: [object Object]  MMM-iFrameReload.js:53:3

what I did also is changing the last Attribute:

				refreshInterval: '10'  //Optional. Default: 3600 = 1 hour

removed and added the ’ around the 10 and added a comma at the end of the line. still the same: iframe gets loaded, but not refreshed.
