[weewx-user] UV Sensor Battery Indicator

[gjr80]

Hi,

Station specific hardware fields like battery levels/hardware states are very 
much station and driver dependent. You may find some info in the comments at 
the start of the your stations driver file. You could also try running WeeWX 
directly (http://weewx.com/docs/usersguide.htm#Running_directly), this will 
cause loop packets and archive records to be displayed on the console (loop 
packets start with LOOP:, archive records start with REC:). It’s quite possible 
the field you are after is appearing in the loop packets and archive records 
but is not displayed in the default reports. If the field is there you can 
display it’s current data in a report using the tag $current.field_name 
(substituting field_name with the actual field name of course).

If you want aggregates or other historical data for the field of interest you 
will need to customise your database to add the field you want to your archive 
(http://weewx.com/docs/customizing.htm#archive_database) or repurpose an 
existing archive field. You will then have access to various aggregates (max, 
min, average etc) over various timeframes (day, week, month etc) in your 
reports.

Re: [weewx-user] require additional external sensors. Max. Number of stations reached

[p q]

You don't have to go with commercial sensors and SDR. And you don't need
another raspberry Pi. Google for Raspberry Pi weather sensors and you
should be able find some examples:

I added my own extra temperature sensor. Project here:

[weewx-user] require additional external sensors. Max. Number of stations reached

[Michael]

Hello,
I use as weather station TFA-Nexus with 5 external sensors 
(temperature+humidity). Now it is so that these 5 external sensors are not 
sufficient and I would like to integrate further external sensors. The 
TFA-Nexus only supports 5 external sensors. 
Weewx runs on a Raspi 3b
If I understand all this correctly I need another Raspi and a USB stick 
that can receive 433 MHz and 868 MHz data and of course more sensors.
The goal is to use up to 8 more external sensors.
Now my questions:
How are these other sensors differentiated? Does each sensor have an 
individual feature which can be read out (e.g. serial number)?
Can anyone recommend me a USB stick and external sensors? 
How can I ensure that the new sensors do not overlap with the already 
existing sensors, or that confusion can occur?

Only as a clarification. I want to keep the existing weather station and 
the data of the new sensors should only be displayed in weewx.

Many thanks for your tips and hints.

[weewx-user] Vantage Vue Wind Direction

['Jake Sales' via weewx-user]

Hello, I’m having a bit of a problem with wind directions. My Vantage reports 
direction wind is from but Wunderground reports it as direction the wind is 
blowing. However, it’s not converting it so I’m 180degrees out on Wunderground. 

I’ve applied an offset in Weewx of 180 but it doesn’t seem to be reporting it 
with the offset to Wunderground.

Does anyone have any ideas what to try?

My setup is Vantage Vue sensors-> Vantage Terminal -> Belfryboys USB data 
logger -> Raspberry Pi 3 -> Weewx -> Wunderground

Thanks

[weewx-user] Re: Import Wind Direction from Vantage Pro2

[shvman]

Hi,


Thanks for the reply.  Thought it was not possible to import directional 
strings..  Wish I could do this myself.  If you think of it and have some 
time in the future AND it's not a big deal, I think it would help those of 
us who are dumping Vantage software on old Windows boxes and moving our 
stations to Linux. 

BTW, the 'wee_import' program works great with a CSV file.  All my other 
data was successfully imported on a 'dry run'.  This is one of the best and 
most completely documented programs I've ever seen.

I'll hold up on this project and do the many other things I got hanging 
here. 

Thanks again, jjs

[weewx-user] UV Sensor Battery Indicator

[Neil S]

So I have just upgraded to 3.9.1 (on Raspberry Pi).  Using the nice new 
skin but cannot work out how to get the UV Sensor battery to show on the 
web page. UV levels etc show OK but cant get battery status to show 
(despite some config file fiddling)

(WRM88 weather station) 

Is it possible?

Neil
