I just rediscovered lego MOC-building as a hobby and I am currently building a 1/12 scale moc which is powered by four buggy motors. The Lego infrared receiver and remotes I own don't seem to be working properly anymore. I guess it's because I haven't used them for the last ten years.
So I'm looking for alternatives. I am owning about fifty lego power functions-motors and would like to use them in the future. I heard about Lego Poweded Up, BuWizz, Sbrick, Cada and Mould King. Please correct me, If I am wrong:
Lego Powered Up: Only works with battery box and motors specifically made for this system
BuWizz: Needs a 300 € battery box, comes with a smartphone app and works with my lego power functions motors
Sbrick: Seems to be not available anymore
Cada and Mould King: They sell remotes and receivers that look like the old lego power funcions remotes and reveivers (or at least look similar). Are they 100 % compatible? Do remotes from Cada or Mould King work with lego receivers or the other way round?
(Mould King has a smartphone app that seems to be a huge data octopus. I find this so distasteful that I would like a "clean" solution.)
