I’ve completed the scripting language part in the templates.In index.template I have added:
[INVERTERCOUNT>1]
<div>
<p><h2>##index.actualsum##</h2></p>
<img src=”##image_actualsum##”>
</div>
[/INVERTERCOUNT]
So if there is more than one inverter this block will be kept into the template, else it will be removed automatically. For now this only works in index.template btw.
