I know that I can see the battery status by going to
Settings -> Sensors -> (Power meter Device ID) -> Status
One of the pieces of information is battery status. And of course I get an on-screen alert when the battery level is low. But is there a way to display the battery level of the power meter as a data field, just as it's possible to display the battery level of the Edge 820 unit itself or the battery level of my Di2?
