So I just got my RM4 Pro and tried to add the integration directly but it didn't seem possible without first adding the device to the local wifi network. After using the Broadlink android app (was hoping to avoid this) I managed to get it connected, and installed the integration after 'unlocking' the device authn.
AFAICT the integration in HA seems ok, but I don't see any facility to add new devices, learn new codes, etc.. I was hoping to use HA to manage all this and uninstall my Broadlink app. Is this not possible ?
