Hey there,
Welcome to Ecotech where nothing is compatible and you must changes everything. I truly wish I could find a solution to this, and for that I’m sorry. But my advice is to not support them. Before hydra was bought out, they were well more ethical and now not as much.
Best advice is to use both lights but run two separate apps or if they are like mine it gives an option to select which one. You then can set the lights the same by aka setting blue to 90 on both etc. I was thinking maybe daisy link them if they have an Ethernet port and (daisy may not be right word), but Y the two cords into your route or whatever you use then link your phone to the router. Problem is they probably thought of this and changed the binary code and language or aka like computers some are 32 bit and 64 bit and need completely separate systems. Just in case I said some wrong words etc (i am terrible with computers but have had to make things like this work while I’m at work; when we can’t wait for IT to show up 9 hours later).
It may help or not but hopefully sparks something that will work.
