Understandably, there is some confusion regarding which Radion models are Mobius controllable. At this time, all models of G5 Radion are fully Mobius compatible right out of the box. As of 7/31/20, all Mobius users have Legacy Radion access and are able to add Mobius Compatible devices to the app. To check if you have access, please open the Mobius app and select the notification icon.
In order for your Radion to be Mobius compatible, it will need to have a black RF Module installed.

XR30w G3/Pro Radions containing a serial number beginning with a 5 also does not have a removable RF Module and will need to be controlled via EcoSmart Live.
