My gyre 330's are set to group 1 and my mp40's are on group 2 (but mostly follow the same programming).
I use sps reef during the day and lps reef during the night.
You'll need the apex link cable to connect the wave engine to your apex, then you'll program via the modes for feeding, water change, etc.... Then you'll have to create some virtual outlets in fusion. I just followed the instructions that Carlos gave on the video for programming feed mode via apex. The key to triggering something in the wave engine via apex is setting the right voltage in the virtual outlet and matching it in the Hydros app.
For example, when I program "storms" which is a repeating trigger, I also have it programmed through the 0-10v, so I can push a button and run the "storms" mode at will.
I'll add a few screenshots.
This is the virtual outlet for triggering "storms". In the Hydros app, I have the trigger voltage set to 4.
Here's the actual variable speed port.
Here's the mode for triggering "storms".
The last two are my schedule with repeating triggers. I have to double/mirror the programming for my mp40's, which gives me independent control.
I know there's a lot of info here, but I can help with one thing at a time, which will make it easier for both. So let me know specifically what you want to do and I'll help. - John
