Resetting Rain Year Start

[Jonathan Ryshpan]

Is there any reason not to change the start of the rain year on a Davis Vantage View from January to October on a system that has been running for a while? Will it corrupt the archive or mess up the system in any other way? The weexd daemon will (of course) be stopped during the change.

When you start weewx, it downloads the start of the rain year from your console and uses that for reporting. It's not stored in the database. So, if you change the rain year, you'll find that rain year reporting will change from January to October.

Delete all your reports and let weewx regenerate them. That way, they'll all use the same rain year start.

I have "changed" the start of the rain year to October, but am now perplexed because the rain year has always been set to start in October. I have reset the start of the rain year and have deleted all the files under /var/www/html/weewx but nothing has changed, as you can see by looking at the web site. What am I missing?

Here is the log of a reset session:

# wee_device --set-rain-year-start=10

Using configuration file /etc/weewx/weewx.conf

Using Vantage driver version 3.5.2 (weewx.drivers.vantage)

Old rain season start is 10, new one is 10.

Old and new rain season starts are the same. Nothing done.

And an extract from weewx.conf:

[Station]
    
   # Description of the station location
   location = "Claremont Hills Oakland, CA"
   ...

   # If you have a website, you may specify an URL
   station_url = http://oaklandweather.ddns.net

   # The start of the rain year (1=January; 10=October, etc.). This is
   # downloaded from the station if the hardware supports it.
   rain_year_start = 10
   ...

It works when I look at it. Make sure you click on the "Year" header under "Statistics." 

Definitely not the most intuitive interface...

Wow! You've had a lot of rain this year.

Just so. I didn't realize that Statistics, etc were live links till today.

Just as you say.

We have more coming tonight and tomorrow. Probably over 40" total for the rain year.
