Is there a widget or app that will allow me to create a screen on the 530 that will show the battery status of all the connected devices: power meter; Varia headlight, Varia radar, speed sensor, cadence sensor, and HRM? I found an app that will show those things, but it can't be configured to do it on ride screens. It'd be nice to have something I see just by cycling through the screens I have set up for rides.
