Steve,

Actually this has been the solution for the rain gauge reports:

21-1-2013 21:56:10.093 : VP2: Setting raintotal from current station value: 17,6000003814697

Just taken from the diags now! Problem solved!

Note that your previous rainfall figures in Cumulus will all be too high, they won't get corrected retrospectively.

(Probably the Envoy identifies itself as a Vantage Pro)
Obviously, someone did not read the documentation supplied with the 'Vantage Pro2 Weather Envoy' (product #: 06316)... :roll:

The Vantage Pro2 Weather Envoy is, indeed, a Vantage Pro2 console ... but without the display or the control buttons.

I'm having a similar problem with the rain totals on my Vantage Pro 2 compared to Cumulus.
In my case it sems to be related to the fact that this morning I changed the "log rollover" from midnight to 0900hrs.
Although I changed it back again, Cumulus is persisting in giving me the total rain from 0900 rather than midnight.
I've checked the rain data logged in "Jan13log.txt" to confirm.
Is there any way to get Cumulas to report todays total from midnight now?

If you are running build 1040 or later can you use one of the Cumulus daily backups to rollback to a previous good date?

You will either have to wait until the next rollover, or do as Paul suggests, and 'rewind' by stopping Cumulus and copying the files from the last backup before you changed your settings. If you're not using a build with the extra backups, you can still use one of the backups that's created every time Cumulus starts up.

I'm running version 1.9.2, build 1032.
I though this was the latest version.

Later builds are 'beta' versions, see the Announcements and News section of the forum. But the build you're using takes 'backups' each time it starts up. The beta version also takes them just after the 'rollover'.

Thanks Steve.
From the look of things Cumulus keeps the last 10 backups in the backup folder.
Unfortunately, attempting to solve the problem, I've stopped and restarted the program more times than that.
The earliest backup now is after the 0900 rollover.

You can rewind manually by editing the files back to the state they would have been in, but that can be tricky. Editing the dates and times in today.ini is what tells Cumulus from what point to re-download the data, but you get duplications if you don't edit all of the files back to the how they were at the same point.

Re: Difference in rainfall on console vs. Cumulus via Envoy

Hello, I am new to weatherstations and Cumulus. I am using Cumulus 1.9.4 build 1082, a Vantage Pro2 console and an Envoy shortly. I don't use other software at the same time to connect to the Envoy.
I also see a difference between the Vantage Pro2 (EU) console and Envoy (firmware 3.12) connected to Cumulus. Last night the Vantage Pro2 console shows 5.2 mm and the combination Envoy/Cumulus shows 6.6 mm. 6.6 divide by 5.2 makes about 1.27. That's the difference between 0.01 inch and 0.2 mm! I also saw values of 0.3 mm in Cumulus which sounds a bit strange to me.

I am in a test period. So I have initialized Envoy with Weatherlink again. I choose 0.2 mm per tip and no calibrations. Now I'll wait for the first rain to see if everything is ok now.
Anyone suggestions what might be wrong?

It sounds to me like you didn't have the Envoy set to the correct value for your rain gauge previously, i.e. 0.2mm if you have installed the metric adaptor. That would account for a value of 0.3mm, if it was set to 0.01 inches per tip previously. Just as was the case with the original poster in this thread.

Just as a point of interest. I bought my VP2 from the distributor here in Australia & it was new stock fresh in from the US & the rain gauge was set to the 0.01" setting. This did surprise me as we use the metric measurement. It was a simple matter to convert it as the parts are supplied with the unit. It has occurred to me that perhaps they ship all the units with the Imperial calibration & it is up to the owners to reset theirs. I don't know if this applies to the UK & EU models, but it might be a good idea to keep it in mind, when calibration issues like these arise.
Incidentally there was a sticker on the rain gauge saying it was set to the 0.01" setting.
