I move from the Archon to the Hydros system but it was over quite a bit of time. I think I started about 3.5 years ago and got a X4 starter kit to begin with. The main reason was the 0-10v inputs. I had plans on using three of those to monitor the level in my three tanks at my mixing station in the garage. So my first few Hydros items were all in the garage. I was able to pass simple signals between the Archon and Hydros. The first 2 things I used the Hydros for other than the water level sensors was ATO and AWC. I used 2 signals from my Archon to my Hydros one was a replacement to a water level sensor in the sump. The Archon would send a dry signal if the Archon sensor was low and the return and skimmer was running and there were no leaks detected. So that signal as far as the Hydros was concerned was a liquid level sensor in the sump. The other signal was similar in it was a ok to do a water change signal. The Hydros had the schedule and would do it when schedule if it had a ok signal from the Archon. I slowly added to the Hydros at first only in the garage so it eventually had full control of the mixing station and RODI in the garage. At that time I was up to 4 controllers. After that I added it to the tank also. I am now up to 14 of the controllers but a controller is a module with a brain so it can be used by itself or with others to make a larger control system. So it is still modular it doesn't have a main brain. It is distributed amongst all the modules.^ This...
If they gave me a incentive to move, i would do also.
But i understand now why people say that Apex bubble is hard to pop.
I have too much invested in Apex... i have 2 DoS + DDR's + Trident + Apex Pro + a whole cache of FMD's.
I would need a significant advantage / reason to go over to coralvue.
