Sorry ipad is not yet supported by the ios app. It will work but it won’t fill the screen. I will look like a stretched iphone app. The android app however supports tablet mode very well.
You could use a web browser to display a mobile version of the MyElectric or MySolarPV Emoncms app module display.
I am running the browser version but I think the issue is none of the JS is supported by the browser versions on ipad1 - I have tried safari, chrome and firefox. And I have upgraded them all as far as they will allow.
The symptoms are the page loads but none of the JS elements (e.g. dials) load.
