My Apex base unit controlling my display system almost crashed my system. Luckily I was home when this happened and noticed. Came down and my lights were off around 1130 am, when lights would typically all be on already. Went back and everything seemed normal and fusion didn't show any alarms. Tried using a slider on fusion and nothing happened, odd. Put my hanna temp checker in the tank, and my display was down to 77.2, this never happens. Scrambled doing a network reset and managed to get it back online, briefly. No idea why heaters parameters hadn't tripped them on to heat.
Turns out, my base unit SD card is corrupt and causing these issues. Of course that took speedy Neptune almost two days to respond while my system limped along. Looks like new base unit it is, and start programming from scratch again, great!
