Re: [weewx-user] spurious gaps within weather data - wh23xx on raspberry pi 3

2018-03-11 Thread Greg Troxel 

One bit of advice:  Do not assume that you only have one problem.  You
might have multiple ones, and that makes debugging much harder.

If you had problems after installing the forecast plugin, then uninstall
it and try for a while.  I don't mean to say that I suspect it's a
problem, but all sorts of things could be going on, like increased CPU
temperature, load on the power supply, or lots of others that no one can
think of.

Hello Vince,

Thanks for the answer. I think it's not easy to convert. In your link, I 
read, "The index is equal to the EAS-weighted irradiance (in watts / m²) x 
40. An index of 10 corresponds to an EAS-weighted irradiance of 0.25 W / 
m², but if I convert my values this does not fit the index on the display 
of the station.
At least I think it's easier to adjust the charts and live with the 
reported values ...

Martin

[weewx-user] spurious gaps within weather data - wh23xx on raspberry pi 3

2018-03-11 Thread Michale Waldor 
I'm a new user to weewx running on a raspberry pi 3 connected to the 
weatherstation Renkforce WH2300. And I have some spurious problems where I 
need some help:

Raspberry pi 3, 16GB sdcard,
network connection via wifi,
2A power supply for raspberry pi,
batteries within weatherstation (BTW I believe that USB connection will 
power weatherstation, too)
cat /etc/issue --> Raspbian GNU/Linux 9, uname -a --> Linux IMURR9 
4.9.59-v7+ #1047 SMP Sun Oct 29 12:19:23 GMT 2017 armv7l

I gradually added functionality to weewx in the following sequence
- base installation weewx 3.8.0 + wh23xx driver 0.14
- nginx Web server on the same pi
- upload towards wunderground
- German Sofaskin_1.1_DE, partly tweaked to match my preferences
- forecast plugin 3.2.19
- pyephem 3.7.6.0
- reboot once per day at around midnight

Everything worked smooth but some problems started after installing the 
forecast plugin. Randomly for a short timespan data from the sensor array 
was missing. The amount of missing data continuously increased from day to 
day. Thus I assumed bad batteries within the sensor array are the problem 
(it worked without any problem for about 2 weeks even for outside 
temperature ~ -10°C). First I tried a reset/resync of my weatherstation. 
Afterwards it worked for 1..2 days, then the gaps increased again (in the 
meantime outside temperature was at +5°C or above). Yesterday the 
connection to the sensor array was more or less completely broken. Thus I 
replaced the orginal rechargeable batteries by standard alkaline batteries 
- immedeately the connection worked smooth again.

Thus: All problems solved (but why do I post that at all)? No, during last 
night again (one small) gap appeared within the data despite new batteries. 
Ok, then I inspected the logfiles from weewx to search for potential 
reasons. I have no real clue about the cause of my problem since there are 
some different kinds of errors:
