ASIAIR Plus dropping guide camera and EAF every night

NoMiSkies

Every night prior to midnight I have been losing the connection to guide camera and EAF. Unfortunately all of the images taken prior to this also get lost. (This also has me baffled). My Autorun always resets to 0/???. None of the images prior to the device drop show up on the USB flash drive.

Typically everything holds together after I drop down and add back the ZWO guide camera or EAF and slide this back to active.

This has been happening now for several weeks.

I have looked at the app's voltage monitor which always shows 13.1 as well as looking at the amps and watts. I never have looked at this when the devices get dropped.

I have considered that possibly this is related to Meridian Flip???

It is just strange that this has occurred almost exclusively just once an evening.

My device is connected by ethernet to a travel router.

My ASIAIR has all of its USB ports filled. I also am using a Pegasus Pocket Box Advanced device which has a couple more USB ports filled as well as powering 2 dew heaters. The PPBA receives it's power from a Jackery Battery and the PPBA sends the power on to the ASIAIR device. Since the ASIAIR maintains a constant 13.1 volts I am thinking that this is feeding properly.

I have run into different issues while imaging with ASIAIR but they are very intermittent so I don't think they are related to my main issue.

I would appreciate any ideas on what could be going on. Perhaps there might be settings that might be incorrect?

I have 2 asiair devices and a new mini. They have always worked flawlessly with my 110vac to 12 vdc, 3-5 amp, power supplies, really, no problems. Then one weekend, it rained and I had this brilliant idea of putting a variable output, regulated power supply (13.2-3-vdc) in place of the 3 small power supplies. Well of course over the next week, all manner of weird problems arose even to the point of the two 1-2 year old units going blank. At first I thought it was an upgrade problem from ZWO. Planned obsolescence, questionable, what could be going on. I put them back on their small power supplies…after a few fits of bewilderment I re-installed the big power supply, adjusted it down to 12.2-12.4 vdc and after a few on / off cycles, both of the ASIAIR units came back on line. No more issues. Proved to me that the units are voltage sensitive.

Robin: What you have done is interesting in a couple ways.
1) I didn’t know that you could use 2 ASIAIR to run a telescope. So, you must be using them to push through power independently with one of the devices not software controlled by the ASIAIR app. It looks as if the ASIAIR can output 3A per output so theoretically 12A of output for each device. I am only using the power outputs on the PPBA which also I believe has a power output max of 12A. I am only using the USB hub of the ASIAIR.
2) I didn’t know that the power could be regulated going into the ASIAIR. I believe the documentation suggests that the ASIAIR handles between 12-15V. Normally this didn’t seem to be a problem for me, but if the power input could be regulated it might be good to try this.
