It seems that the graph has stopped updating since around 3am last night. I have only had the device installed since around 10PM last night but i was receiving data. I do still see the power usage being correctly updated in real time. Oddly enough i actually did also see data up until 7:30am this morning but then that data disappeared all the way back to 3am. This lack of data is consistent both on the android app and through the web interface. The realtime (15 minute) graph shows the wattage number being updated in the top right corner but is not graphing anything.
