Been using Venus OS Hosted Web App for a while and noticed the DC Loads section flash On|Off every now and then.
I suspect that when the DC Loads reach a 0 value it removes the entry completely. Could I suggest that if the 'Has DC' setting is ON that the indicator stays permanent. These are the images of the two screens - note the DC Loads missing in the first one, give it a couple of seconds and it returns as per the second image.
