In case anyone else runs into this issue, I will share my problem and solution.

 

I bought a Deep Sky Dad motorized flat panel with its special ASIAIR power cable. But I ran into a problem using it last night. I don't think the ASIAIR can run the flat panel properly if you have too many power drawing  items connected. My flats were behaving erratically. The mean ADU value was fluctuating wildly from flat to flat even though I was not touching the power setting. I suspected it was a power issue. I have the AA+ pretty well maxed out with the following items powered through the power ports and the  various USB ports

 

1. ASI533MM pro with TEC
2. ASI174MM guide camera
3. AM5 mount
4. ASI EFW filter wheel
5. DEW NOT heater strip for a 5 inch refractor
6. EAF focuser
7. Deep Sky Dad motorized flat panel

 

Apparently these item draw too much total power for the ASIR to distribute correctly. But the fix was simple. Turn off the heater strip while taking the flat. Flats were perfect after I did this. Then turn the heater back on when done with flats. So if you see some weird flat panel behavior, you may need to try something similar.

Thanks for sharing John, I had some issues with the air, cable and DSD panel.  What you say makes a lot of sense.

Truth be told, I know next to nothing about electronics so I may have the reasoning all wrong, but what I did worked!

Just thought I would add a suggestion/question.  Are you powering your AM5 from the ASIAIR?  I Run my ASIAIR Plus with the following;

AM5N powered by Bluetti, ASIAIR and power to Deepsky Dad flat panel through a "Y" splitter from power output on AM5N deck, ZWO EAF, ASI2600MC, Guide scope, and AM5N control all to ASIAIR USB slots.  ZWO filter wheel and ZWO CAA to usb slots on camera.  Camera to power 1, pocket router to power 2, Dew heaters to power 3 and Flat panel control to power 4.  All seems to work well for me.
