For devices which do not report measurements like battery level frequently, such as once daily, the 'Device and Communication' widget inside the info tab within Device Management does not report any useful information. Ideally, as with other data explorer graphs, there would be the option to select the time span of search, such as "Last hour", "Last day", "Last week", "Last month", etc.. This would then make the widget useful.
Dear Nick, thanks a lot for your feedback. We do agree that the "Device and Communication" widget can be improved and will add this improvement to our backlog. Unfortunately, we cannot yet provide any timeline indications.
