Ive had a few emails back and forth with the developer and been very happy with the responsiveness to my questions.
However, although this application allows access to all the graphs for a device, it REALLY needs to include a list of the graphs to choose from. Currently, when you select a device, you then have to flip through the graphs for that device, instead of being able to see a list and select a graph easily.
If this and a few UI bugs (forgets you were in edit mode when you add a device, if it indicates there is a server error, it will then show you previous device listing for that instance, but will not let you view any graphs) were fixed, I would rate this 5 stars..
