If you need to monitor the battery of a battery driven unit you want to have VCC enabled. It must be done at compile time since it will take over the analog function internally.

If the variable output is "-1.0" it means that the VCC is not activated or that a reading has not been completed (could be due to incorrect cabling etc. etc.).

I remember that,...
if the "Delay" (Interval) for the Vcc-System-Device is set to 0, it's the same effect ;)

But TD-er had offered, that he change the behavior of the 0-delay-value of the devices, that these will be published once to the controller !?

Ok, I will leave it as it is for now. It's only a notice... We'll have to do a complete update of the wiki when we release 2.1
