Unexpected Rain Reset
I know I'm Still Stuck on an old Version, but struck an interesting Anomaly last night.
Two of my Stations did their Rain Reset at Midnight instead of the expected 9:00am.
Rain here can be patchy, but I could look back a few days on the Graphs & see that it didn't happen on the 2 previous events.
Could it be a code issue triggered by Jan 31st, or change of Month?
Other Relevant fact is that this only occurred on my two rPi installs,
Not my Primary Windows install.
Effected Stations are w2.inverellit.com & s7.inverellit.com
Cheers

Re: Unexpected Rain Reset
Just guessing, but I would check the Ecowitt GW settings page of Rain totals. Maybe the ”Reset Daily Rain at” -setting has been reset for some reason?
Edit. I mean the gateways themselves, not a setting in CMX

Re: Unexpected Rain Reset
Good Point.
Just Checked the GW1100 that's Local & the Settings look correct.
They are:-
Reset Daily Rain at 9:00am
Reset Weekly Rain at Sunday
Rainfall Season January
Not sure how the Rainfall Season factors in at the reset as the month did change from January to February when the reset happened.
Probably more relevant than rPi Vs Windows is the fact that the two that reset were both Ecowitt.
My Davis VP2, on Windows reset as expected.
Will check the other remote Ecowiit when I can get near a VPN.

Re: Unexpected Rain Reset
Your gateways are GW1100 and not GW1000 as your websites say? If that is the case, what firmware version are you running? Because this might also be a bug introduced in recent firmware versions.
Anyway I think it is quite unlikely, that this would be a CMX v3 bug that no-one noticed before. But who knows, noticing unexpected midnigh reset needs 9am rollover to be in use, and I’m not sure how commonly it is used.

Re: Unexpected Rain Reset
Actually it is a GW1000, I also have two GW1100C's but they are for other purposes like Home Assistant etc.
Version or the GW1000, I Can't see in WsView, but it does offer an upgrade to 1.7.7.
Also Don't see an option for the Rainfall Reset in WsView though.

Can you post the log files that cover the times it went wrong.

Re: Unexpected Rain Reset
I have two GW1000B gateways, both with current firmware (v1.7.7). For some reason, both showed February as Rainfall Season in the WSView plus app. Pressing the reset button on the rain totals screen changed it back to January.
I have attached my log file with the reset error at line 2666

Re: Unexpected Rain Reset
OK, so the log file does show the GW resetting its annual rain total to zero at midnight on the rollover to 1st Feb. CMX detected the reset and coped with it correctly.
I'm not sure about your statement "Two of my Stations did their Rain Reset at Midnight instead of the expected 9:00am." as CMX is configured to perform the daily rollover at midnight not 9am?

Re: Unexpected Rain Reset
@mcrossley did you notice that the logfile was from different person than who originally opened this thread…

Re: Unexpected Rain Reset
Will get to it in a day or two when I'm back near my devices.
should have thought that way from the start of the post.
Cheers.
