I’m in the market for a controller and I a few specific needs. I’m out of town frequently and often for prolonged periods of time. I usually have a house sitter but they are often not aquarists. Most of my stuff is already automated and I mostly need a controller for alerts when something is failing. Water levels, wet floors, temperature,pH,and power outages. I’d like a back up cellular unit for text alerts when the WiFi goes down. I need to monitor 3 systems: the reef, and indoor koi pond, and an outdoor koi pond. dKH monitoring, when it comes out, will be a big plus for the reef. I’ve been looking at the Profilux and Apex. What do you folks suggest?
