Strange reset during the day

Ross, from your stats, do you think that it could have been resetting when your batteries
were full rather than needing a good charge ?   Or, maybe when the batteries were
full AND loads were light ?

Bob, I don't think so. The times don't fit with the batteries being full. So I've done some further analysis of the logs. The following is the date/time I detected the RESET (so some time in the previous 5 mins). The next 3 fields are the battery volts, the charging power and charge state (register 4120), followed by what the same three were immediately PRIOR to the reset...

i have to chip in here because I am having the same issue  I posted earlier that the machine goes into resting

Confirmed 1370 4/8.

OK, that's new enough.  Have you seen it do this since then ?

How often has it reset during the day that you know of ?

boB

It has not reset again since my post and this was the first time I've noticed it reset in months.

When the Classic reset, were the batteries full  or close to being full ??

Thought I would add my observations:

Just got my Midnite Classic 150 Lite installed a few days ago. It had a couple of resets yesterday in "Solar" mode, mid-day I switched to Legacy and today I've had at least 4(nice sunny day).  I am static IP, and watching with the local app, and mymidnite. The "Daily values" KWh collected so far gets set to zero after the reset. I get "The Connection was Closed" & disconnected from the Local App and am able to instantly re-open it.
My "Lifetime values" do not seem to be updating properly as well.

Using MyMidnite.com "Energy" graph, I can see the resets in that "Energy Collected" will gradually go up, then you see 'mid-day' it go down to 0 and start going up again.

No firmware updates from 1181 it came with, though it seems those here who have updated are still having the resets, perhaps wait until the next-one which I would hope will resolve the issue?


later.

Again, I must ask, are your batteries full at all during the day when you see these resets ?

For me, it resets all through the day(12.2V) on the way up to and including absorb(14.4) and float(13.3).
Had a few more resets today...

After a reset it forgets it was ever in/finished absorb and trys putting it in absorb for X hours/mins before going to float again.. So I force float manually in config.
Having the "Lite" I just have the first 2 jumpers set to custom, and configure Static IP and most everything else from Local App.
The first couple days I ran it stock(jumpered) 12v, dynamic IP etc, I only noticed it reset once, I suppose I should put it back and see how much more stable it is there.

Dang !    OK, I was kind of hoping it was happening only when batteries were full.

I don't suppose you have ever noticed it reset while resting ?   RossW seems to see that his only resets while running.

Didn't touch/open "Local App" today, made no other changes... No detected resets for me today(vs 4+ each day previous couple of days).

Will have to test it a few more days, but looks like it has something to do with Local App interaction(when in custom config through local App, possibly). Static IP etc...

Well, it used to be related to the local app and/or connections to the Classic over the Ethernet but I thought
we had fixed that.

Yes, please let it go another day or two and let's see if that keeps it from resetting.

Thank you for doing that !

Bob, please feel free to move this elsewhere if its more appropriate.

Tom (and at least one other forum member that I know of) has been having an issue where the classic communications just "stops". The classic still responds to ICMP echo-request (ping) packets, and is "listening" in as much as you can attempt to connect via TCP on the modbus port (502), however the classic refuses connections. When this happens, it appears the only way to recover is to reboot the classic.

It's been getting quite annoying for some.
Well, today I logged in on one of Tom's rPi's and wrote some simple code. (If anyone else wants to try this, let me know and I'll post it here). Basically, I set off a tcpdump which constantly monitored communications to/from one classic. A circular buffer holds the last couple of hundred lines of output. When this condition is detected (identified by the logging stopping), I write out the buffer to see what happened immediately before. (This is so I don't go wearing out his flash memory!)

Caught one just now.

It looks like everything was completely normal right up to the connection close, but the following attempt to connect failed. So I don't think it's my newmodbus - but happened after this reading and before the next.
Have the full packet contents if you want it, but here's the end of the last working poll and the start of the next.

192.168.2.88 is the rpi, .129 is the classic.

Hi,

I am seeing similar behavior here.   I have four classic 250's running v1401. Two days ago at 1500 eastern one of them stopped talking to mymidnite.    It continued to respond to the local status panel application.   i rebooted it a few hours later and it started talking immediately to mymidnite.

Last might at 2330 another stopped talking to mymidnite.  I haven't rebooted it yet.  Sometime between last night at 2330 and this morning it also stopped responding to the local status panel application. 

TomW

And the plot thickens....

This refusal to communicate is pesky but I am not sure it is the same fault that makes it reset? Seems most of us do a power cycle to recover and that obviously resets the Classic.

I have had mine blocked from communicating with mymidnite to see if it was part of the issue. It is not. I may start dumping via the USB port and see if that yields some clues.

Ross has mine under constant scrutiny so maybe a pattern will emerge.

Just my current observations.

My Midnite and other communications from the Ethernet port are different, I'm pretty sure, from
the resetting of the Classic itself.

Some of the My Midnite trouble bay be My Midnite itself or in the Classic or of course, both in
some way.

We are still working on the problem.

If the Local App quit communicating with the Classic, make sure the Classic itself is running
and charging batteries, which is its main function, but the communications is very important
too.
