If you're interested in Roon Ready, we plan to have it integrated in Q1 2023. This will happen through an automatic software update. 

Please note: this is available for WiiM Pro first. For the WiiM Mini, due to Mini's limited memory, we'll have a specific device FW to support Roon Ready together with some basic functions such as AirPlay 2, Spotify Connect and TIDAL Connect..While the normal device firmware won't support Roon Ready but with more complete features.
