I'm not 100% sure on this, but I think you can only have one active "connection" at a time from a device to your Rise. So if you have the Rise added as a sensor to your Edge 530 then that would count as one connection (via ANT+) - and that would prevent the STEPS datafield also connecting (via Bluetooth). Or if you are using the Orbea RS Toolbox app that also counts as one connection (and prevents other stuff connecting).
But if you have your Rise connected as a sensor to the Edge 530 then you should have no need to use the STEPS datafield anyway

All the information should be available directly using the standard fields included in the Edge 530 (e.g. battery, assist mode etc). I only added support for the Edge devices because someone asked - it's really intended for the watches since they can't add Shimano e-bikes directly as a sensor.
Is there something you are trying to use the STEPS datafield for which isn't possible using the standard fields?
I'm also not sure if you can have 2 devices connected at once to the same e-bike - I suspect not. E.g. as a sensor on an Edge device, and also using the STEPS datafield on a watch at the same time.
