Apex Modules change address after power interuptions

Ain't that the bleedin' truth...

Ha, in all these years I had no idea this was possible.

Caveat is to remember to program the power fail alarm code to shut down all the power hogs in outlet programming so they don’t immediately drain a small ups. Doesn’t do much good if the lights, heater, chiller, uv, etc are all still running on a 750w computer ups. If a blue yeti wasn’t so expensive I’d have one for sure. If I could see what I was doing and keep the tremors down a diy project would be in the works

It's kind of counter intuitive though to detect power present on the power jack. I think of the power jack as a back up power input in case I don't want to use the EB8 and want to just run the head unit with probes. And if that's the case, there is no point in detecting the power on it as the head unit would be off anyway.

Detecting it at the power jack suggests that the purpose of the power jack is explicitly to know if the power at the wall is present. Oh well...

My guess is I got a power surge that either bypassed the house surge protector, or one that hit after the main one was tripped, that crashed the apex brain.

Somehow my restart procedures caused the readdressing issues, or it could have happened during the surge itself.

The fact it happened twice is why Im putting the cherry on top of my power backup systems.

Well I had another power outage and now I have new problem. My apex head unit appears to have gone nuts.

The ethernet adapter no longer works, my 0-10v outputs no longer work and all of my modules and EB8s are showing up missing. They come in and out when I reboot but never stay long.

They show disconnected but some of the outlets can still be controlled.

I have no idea whats happening here and I leave for a week in a few days.

This new apex has me pulling my hair out

Well now the only thing working is the wifi and sensors on the head unit.

It has zero connection or control of anything, and I am getting a replacement from Neptune.

Im really hoping I just got a defective unit since it was one of the first A3's available, and Im praying whatever issues it had didnt take out any other modules.

If that was the case, the head unit wouldn't boot at all.

One of the two things happened here: (a) all modules somehow lost the memory of the head unit serial number and forced a new module connect event or (b) the head unit failed to negotiate a reconnect with each module and did a new module connect routine instead.

"a" is highly unlikely to happen to all modules at once. What remains is "b". Again, the logic for module connect/reconnect is very very broken in the head unit code and it becomes more and more apparent the more modules you have connected. If you put the head unit on a UPS, at least it prevents a whole system reconnect every time your lights flicker.

My apex does the exact same thing. If my power cuts out for 5 seconds or 5 hours when I finally get the apex to reboot and connect I ll have 11 missing modules and 11 new modules. The only fix I know is to do as the OP said, figure out which module is which now, then reprogram everything. It very very frustrating.

I'll report same exact thing happens to me now. It never happened to me before, but now I added a second EB32 a few of my addresses reset/change as mentioned above when there is a power outage
