You automated your tank that's nice and I like that but its not necessary for most of us, its like automating your house to be like Bill Gates house, cool to have but not needed.
Leak detection can be achieved with a $10 leak detector from home depot, beeps loud as hell. One should set up a tank to prevent skimmer from overflowing and dumping 20 gallons on floor, Apex can't save you if you dont set up with safety in mind.
ATO can be setup for under $50 with autotopoff.com, you have to purchase additional stuff for the apex to do that.
Top off low alert, the reserve pump is our alert, the pump lets you know when the reserve is low.
Camera to see tank, nice, useless if you are in Cancun vacationing and it's not my child, a fish tank does not need a room monitor.
No one needs to be raising and lowering tank temperature, it should be set to a specific temp, Apex is handy if temp does above or below a set number bc it would indicate something is wrong.
I can go on and on, I don't live alone and neither do most of us. If something is wrong my family tells me, they stare at the tank more than I do.
If a tank springs a leak on the actual tank silicone there is no digital controller that will save you or help you.
Like I said, great toy and if you like automation and spending $$$$ its is neat to have, not necessary and it does not save you if you are truly away from home, you still need a tank sitter to troubleshoot asap.
I disagree with the thermometer part - I don't have SPS (yet) but I find my Apex invaluable. It controls my ATO, tells me when my ATO chamber is nearly empty, allows me to see my tank remotely from via a camera, has leak detection with SMS messaging, allows me to turn off pumps, skimmer, ATO, anything with the push of a button, tells me if my tank water is too high, tells me if its too low, not only does it tell me the temp, it allows me to raise or lower it - all of these things can be done remotely too.
It's one of those things that once you get used to it, I find my thinking why I didn't do it ages ago.
