It's very cool to see a big name company actively targeting Reef Angel as a controller option for their products. Congratulations, Roberto

I'm guessing it's just a plug and play setup and you can swap out the existing sensors with their version. The instruction manual doesn't specify anything specific for interfacing with the RA, so I'm guessing the RA will interpret it exactly the same as the standard sensors.
