VP 2 archive interval vs database vs Wunderground update

[brisguy foo]

Hi All,

Just got weewx running last week on a RP zero and have it successfully uploading to Wunderground. I did not opt for the Rapidfire mode since the user info seemed to indicate this was risky and/or unnecessary. As a result, my PWS page only updates once every 30 minutes since  that is the archive interval on my Vantage Pro 2. I was about to change the archive interval using wee_device, but it gave me this message: 'Old archive interval is 30 minutes, new one will be 10 minutes. Proceeding will change the archive interval as well as erase all old archive records.'

I have several questions:

1. I don't really want to lose the two months of data in my data logger - specifically the temps and rain totals. I tried changing the weewx.conf file to Rapidfire=True to get faster updates, but there was no change. Do I have to change the archive interval in order to get faster Wunderground updates?

2. Will this change also affect my weewx database?

3. I find the database documentation confusing. It starts by saying two types of database can be used, but seems to indicate that the user must choose and install one. However, I checked under /var/lib/weewx and found that I do have a weewx.sdb file, so apparently, I am using SQLite even though I did not do anything other than the normal weewx install. Will this db have all the data from my data logger or just the new records that weewx has created?

4. Assuming I DO have to change the archive interval in order to get faster updates, is there a way for me restore the lost data by updating the db and if I do so, will it be accessible using weewx reports?

Thanks,  Stan

Yes - sqlite3 is the default

Weewx will backfill anything it can find in the logger from a VP2.

4. Assuming I DO have to change the archive interval in order to get faster updates, is there a way for me restore the lost data by updating the db and if I do so, will it be accessible using weewx reports?

Weewx reports and graphs whatever is in the database, so if you can get the data into it, the report/graphing engines will report/display it.
