On the topics of negative numbers, I have also realized that in cases where I shutdown weewx running on Pi, unplug the USB cable running to the WMR200, plug it back and restart the weewx, sometimes I see -ve value for rain getting populated in the database which I have to manually remove.

Thanks, Chris I worry that this approach doesn't cover the case where the "previous" record has, say, a timestamp far in the future. This patch would cause all of the remaining records to get thrown out, but the "future" record to be kept. In any case, it's way better than what we have, which all

I suppose if the archived packets are presented out of order there could be a negative interval... I have not seen this but the wmr200 is full of wonderful surprises. One potential drive-by fix is to drop all packets satisfying this failing condition...here is one untested fix: $ git diff dif

Good. Looking through the WMR200 driver code (I didn't write it), it appears that a positive value for 'interval' is not guaranteed. I'll ask the author to take a look at it. -tk On Fri, Sep 14, 2018 at 5:44 AM Rahul Bedi wrote: > Yup found a record with -ve interval, changed that to 5 as that

Yup found a record with -ve interval, changed that to 5 as thats what I am using. And problem fixed !! Thanks a lot. Not sure how this bad data entered into the db. Will be great if there is utility that finds such errors in the db and flags them. - Rahul On Fri, Sep 14, 2018 at 5:48 PM Thoma

I think the thing to do is to figure out how a negative value got in there, fix that, then rebuild the daily summaries. One possibility is that a record in your database has a negative value for 'interval' --- the time length of an archive record. Let's check that. *sqlite3 /var/lib/weewx/weewx.s

You're on the right track: there must be an bad value in your database. Did you, by any chance, use a visual sql editor? They often put null strings in the database. In any case, the field 'wsquaresum' and 'sumtime' are used by rms. So, try this: *sqlite3 /var/lib/weewx/weewx.sdb* sqlite> *SELECT

Line 1314 is calculating an rms value. Make sure you're doing this against observation type 'wind'. For example $month.outTemp.rms could give you that error. -tk On Thu, Sep 13, 2018 at 2:11 PM gjr80 wrote: > Hi, > > I would suspect some dodgy data in your daily summaries. You said you > rebuil
