Add gaps in the graph

Is there a way to configure the graph so that it doesn’t connect the dots between two data points spanning a power outage?

Another thought I had was to power the iotawatt with a ups. Then perhaps the power would at least drop to zero during the outage.

Not in Graph+. Either way its pretty obvious that there was an outage.

That would work as long as the AC adapter isn’t on the UPS as well. I’d consider one of the mini-USB UPS units with Lithium batteries.
