It is slated for 3.0 . I was originally hoping for 2.0, but after using MP10, Icecap 1K and jebao, I felt that most wave maker comes with their controller, and all we need is to start/stop them during feed mode, which reef-pi can do already. I was also not very familiar with the BLDC driver (something we need for wavemakers). But I am shooting for this in 3.0, and if you have any specific thoughts/advice please share it here:
