[weewx-user] Issues after weather station downtime

[david_h]

Hi  - I had a problem with my Davis Vantage Pro2 where it was not 
transmitting data for about 2 weeks.  After some maintenance it has started 
working again today, but when I get weewx going again, although the current 
weather readings are fine on my weather station website, the reports and 
graphs etc are all as at the date of the weather station failure.  I am 
getting the following errors from weewx in my Rpi syslog file:

I am using the belchertown skin.

Any ideas as to how I correct this please?

Many thanks

Re: [weewx-user] Issues after weather station downtime

[Tom Keffer]

Most likely this is a problem in the Belchertown skin: it forgot that
values can sometimes be Python None. You'll have to ask the skin author.

There may be other problems (such as a corrupt logger), but the log excerpt
is too short to tell.

[weewx-user] SDR and Backfill

[Stefanos Kalaitzis]

Hi ... I am running weewx with sdr driver without any problem a long time 
now... but i noticed that when we have a power off and and rain falls for 
that period , when it comes up weewx doesn't back fill the amount of rain 

i dont know if weewx stores the last value of rain total so then its easy 
to calculate the missing values or if i must do some changes to weewx.conf 
or sdr.py

thank u in advanced

[weewx-user] Re: SDR and Backfill

[vince]

Where would weewx get the data from ?

If you lose power, your SDR isn't listening to the sensors, so how could 
weewx know what the weather conditions were ?

How is your VP2 connected to the pi ?Are you using some non-Davis 
logger or the like ?

It's connected via USB to the Davis logger

Re: [weewx-user] Re: Vanage Pro 2 crashes WeeWx daily

[Tom Keffer]

We have seen this a few times. Things to try:

1. Try unplugging the logger, then plugging it back in.

2. If that doesn't work, try purging "modemmanager":


*sudo apt purge modemmanager*

3. If that doesn't work, try clearing the logger memory
.

If that doesn't work, let us know, but this time include more of the log,
and please do not use a screenshot. See the wiki article *Help! Posting to
weewx user
*.

[weewx-user] Re: SDR and Backfill

[Stefanos Kalaitzis]

I see your point and i fully understand it but i dont care for other values 
when we have power off except for rain 
For example my station calculate rain from rain total and if for example my 
rain total is 20mm  (weewx is calculating ,20 -20 = 0mm which is right, new 
total - old total) and we have power off ,and for that period 5mm fall , i 
think that the station because has batteries transmits 25mm rain total but 
of course sdr is off   So when weewx start again loop periods and gets 
data from sdr sorry the rain total will be 25mm and if it has saved the 
last value of rain total then it is 25 - 20 = 5 mm

[weewx-user] Weewx Web Server Question from a noob

[Kruse Ludington]

1. I have an Ambient Weather WS-2902C already fully configured, sending 
data via it's console on a home network to Ambientweather.net, Wunderground 
and Weathercloud. It has an additional 4th option to send data to 
"Customized" with user-definable related Server IP/Hostname, path, and port.


2. I also have a Raspberry PI 4B 8GB running on a 1TB SSD (instead of a 
MicroSD Card), and I've gotten WeeWx installed on same. The WS-2902C and 
the PI are both on the same network.


As a noob at this - can someone point me in the right direction as far as 
how to get the data from #1  "Customized" into #2 WeeWx on the PI - without 
reinventing the wheel? (Basically just get the Apache 2 that was installed 
as part of WeeWx - listening to "customized" ?)
