Describing my approach to properly install WeeWX on a virtual server which

creates the [weather page](https://wx.oe7drt.com/) and also uploads my weather
|
|
data to the [APRS-IS network](http://www.aprs-is.net/).

## Update on 16<sup>th</sup> July 2023
|
|
|
|
{{< alert >}}
|
|
Okay, just for your information. I no longer use Redhat on my servers and
|
|
the following mentioned weewx-extension does no longer work, because Netatmo
|
|
has [changed their authentication policy][1] for development apps and do
|
|
not allow simple password authentications any more.
|
|
|
|
[1]: https://dev.netatmo.com/apidocumentation/oauth#authorization-code
|
|
|
|
{{< /alert >}}
|
|
|
|
That means we have to update the extension to a fork that is recently updated.
|
|
|
|
There are two Follow-up posts to this article that show the migration to an
|
|
OpenBSD server as well as the replacement of the netatmo weewx-extension.
|
|
|
|
- [Moving WeeWX to OpenBSD]({{< ref "posts/2023/41-moving-weewx-to-openbsd" >}})
|
|
- [Update WeeWX extension]({{< ref "posts/2023/47-update-weewx-netatmo-extension" >}})
|
|
|
|
I recommend reading the last one to get a working setup. If you want to have a
|
|
nice status message on APRS I also recommend reading the first one too, because
|
|
it includes a little script to accomplish that with python.
|
|
|
|
## Preparation
|
|
|
|
{{< alert >}}
|
|
As I'm using a redhat based distribution I installed WeeWX with some help of
|
|
<https://weewx.com/docs/redhat.htm>. You may also need an account on
|
|
<https://dev.netatmo.com/> for this to work. There you get your _client ID_ and
|
|
_client secret_ tokens that you will later need to reconfigure WeeWX to make
|
|
use of the netatmo driver extension.
|
|
Also note, that most commands (if not all) here have to be run as the root user.
|
|
{{< /alert >}}
|
|
|
|
First of all, install `epel-release` so you can install `python3-cheetah` finally.
|
|
|
|
```console
|
|
# yum install epel-release
|
|
# yum install python3-cheetah
|
|
```
|
|
|
|
Continue with adding the repository of WeeWX to your system and install WeeWX.
|
|
|
|
```console
|
|
# rpm --import https://weewx.com/keys.html
|
|
# curl -s https://weewx.com/yum/weewx-el8.repo | tee /etc/yum.repos.d/weewx.repo
|
|
```
|
|
|
|
```console
|
|
# dnf install weewx
|
|
```
|
|
|
|
Look out for `/var/log/messages` in order to see if WeeWX is already running
|
|
(Abort with <kbd>Ctrl</kbd>+<kbd>C</kbd>).
|
|
|
|
```console
|
|
# tail -f /var/log/messages
|
|
```
|
|
|
|
## Configuration of WeeWX
|
|
|
|
Stop WeeWX and remove the database for now.
|
|
|
|
```console
|
|
# /etc/init.d/weewx stop
|
|
# rm /var/lib/weewx/weewx.sdb
|
|
```
|
|
|
|
## Installation of netatmo driver
|
|
|
|
There are more extensions for Netatmo out there, the original extension is the
|
|
one from [matthewwall](https://github.com/matthewwall/weewx-netatmo) -- but this
|
|
won't work with WeeWX 4.x and up.
|
|
So I had to find another one, which I did. It's from
|
|
[bricebou](https://github.com/bricebou/weewx-netatmo), who made a fork of the
|
|
original to be compatible with Python 3 (I think that is required now by WeeWX 4.x).
|
|
|
|
```console
|
|
# wget -O weewx-netatmo.zip https://github.com/bricebou/weewx-netatmo/archive/master.zip
|
|
# wee_extension --install weewx-netatmo.zip
|
|
# wee_config --reconfigure
|
|
```
|
|
|
|
Have a look at the file `/etc/weewx/weewx.conf` because it sometimes happens,
|
|
that the configuration is not properly written.
|
|
|
|
## Starting WeeWX again
|
|
|
|
You can also use `systemctl start weewx` instead.
|
|
|
|
```console
|
|
# /etc/init.d/weewx start
|
|
```
|
|
|
|
## Localisation
|
|
|
|
The setup is done, although if you like your pages with another locale you may
|
|
want to alter the file `/usr/share/weewx/user/extensions.py`.
|
|
|
|
```python
|
|
# file: "/usr/share/weewx/user/extensions.py"
|
|
#
|
|
# Copyright (c) 2009-2015 Tom Keffer <tkeffer@gmail.com>

# See the file LICENSE.txt for your full rights.
|
|
#
|
|
|
|
"""User extensions module
|
|
|
|
This module is imported from the main executable, so anything put here will be
|
|
executed before anything else happens. This makes it a good place to put user
|
|
extensions.
|
|
"""
|
|
|
|
import locale
|
|
# This will use the locale specified by the environment variable 'LANG'
|
|
# Other options are possible. See:
|
|
# http://docs.python.org/2/library/locale.html#locale.setlocale
|
|
locale.setlocale(locale.LC_ALL, 'de_AT.UTF-8')
|
|
```
|
|
|
|
## Pushing weather data to APRS-IS
|
|
|
|
Make sure you get a similar entry in your `/etc/weewx/weewx.conf` file:
|
|
|
|
```toml
|
|
# file: "/etc/weewx/weewx.conf"
|
|
...
|
|
|
|
[StdRESTful]
|
|
[[CWOP]]
|
|
enable = true
|
|
station = "n0call-13"
|
|
passcode = "your_aprs-fi_passcode"
|
|
post_interval = 300
|
|
|
|
...
|
|
|
|
```
|
|
|
|
Now, you could also join CWOP over here: <http://www.findu.com/citizenweather/signup.html>.
|
|
I don't remember correctly, but I don't think you'll need that to just transport
|
|
your weather data into <https://apsr.fi/>.
|
|
|
|
## Going further
|
|
|
|
{{< alert >}}
|
|
**Advanced computer skills may be required for this**. You may end up editing
|
|
some python scripts to finally get what you want. But if you want to learn
|
|
something new, your weather page may benefit from that.
|
|
{{< /alert >}}
|
|
|
|
You may also want to inspect the installed skins (templates) which reside in
|
|
`/etc/weewx/skins` -- adopt them to your needs and enable some more reports in
|
|
`[StdReport]` like `[[SeasonsReport]]`. Adopt everything and make sure to read
|
|
throughout the [documentation](https://weewx.com/docs/usersguide.htm) -- that
|
|
helped me a lot.
|
|
|
|
When I got my virtual server to host WeeWX I also ended up installing nginx on
|
|
it and I finally configured it to present the weather pages (SeasonsReports)
|
|
from WeeWX.
|
|
|
|

|
|
|
|
The link is also on the bottom of every page aswell and the website looks
|
|
something like this:

|
## Update on December 25, 2022
|
|
|
|
My station runs for a while now and I wasn't sure if I continue using Netatmo
|
|
for my weather station, but since the stations works quite well I bought a rain
|
|
and wind sensor the recent days. The first test run went good and it was easy
|
|
to implement the new devices.
|
|
|
|
But there are a few notes to remember. As there are more than one point, I'll
|
|
put them down into separate headings.
|
|
|
|
### Change the comment visible on the aprs.fi website
|
|
|
|
If you want to change the comment that is visible on `aprs.fi` you have to change
|
|
the source of a python file within the WeeWX package. As I upgraded WeeWX when
|
|
I installed the new devices that file got overwritten and it took me (again) a
|
|
few moments to find the right place again. Now, for the future: the file I
|
|
talk about is `/usr/share/weewx/weewx/restx.py` and you may look somewhere near
|
|
the line 1285. I show you an excerpt of my current (already modified) file:
|
|
|
|
```py {linenos=table,hl_lines="5-6",linenostart=1281}
|
|
else:
|
|
_radiation_str = ""
|
|
|
|
# Station equipment
|
|
#_equipment_str = ".weewx-%s-%s" % (weewx.__version__, self.station_type)
|
|
_equipment_str = "https://wx.oe7drt.com/"
|
|
|
|
_tnc_packet = ''.join([_prefix, _time_str, _latlon_str, _wt_str,
|
|
_rain_str, _baro_str, _humid_str,
|
|
_radiation_str, _equipment_str, "\r\n"])
|
|
|
|
# show the packet in the logs for debug
|
|
if weewx.debug >= 2:
|
|
log.debug("CWOP: packet: '%s'", _tnc_packet.rstrip('\r\n'))
|
|
|
|
return _tnc_packet
|
|
```
|
|
|
|
Line 5 and 6 (highlighted) shows the old and new line. Should work fine.
|
|
|
|
### Install a new (and more modern) theme
|
|
|
|
That actually looks like a modern website. Although, I had to re-create some
|
|
entries for the sensor-images. As this sucks pain, I'll leave it with only
|
|
having 1-day images. They are quite useless, but I may find another day.
|
|
Or not, we will see...
|
|
|
|
The name of the skin is [**NeoWX Material**](https://neoground.com/projects/neowx-material)
|
|
and I like it very much. Another nice skin would be
|
|
[Rabenwetter](https://rabenwetter.de/info.html) that you might have a look on too.
|
|
|
|
But back to business :grin:
|
|
|
|
The installation is very easy:
|
|
|
|
- download
|
|
<https://neoground.com/projects/neowx-material#section-download>
|
|
|
|
- install
|
|
|
|
```console
|
|
# wee_extension --install=neowx-material.zip
|
|
```
|
|
|
|
- restart
|
|
```console
|
|
# systemctl restart weewx
|
|
```
|
|
|
|
I usually don't give this hint: note the `#` at the beginning of these command
|
|
lines. That means to run those commands as **root**.
|
|
|
|
Read [the docs](https://github.com/neoground/neowx-material#installation) and
|
|
you should be good to go.
|
|
|
|
I did already had the `python3-ephem` package installed, I used the Almanac pages
|
|
already in the older (default) Seasons skin.
|
|
|
|
```console
|
|
# dnf install python3-ephem
|
|
```
|
|
|
|
The new theme looks like this:
|
|
|
|
{{< figure src="wx-main_new.png" alt="preview of the new theme/skin" >}}
|
|
|
|
### Some other thoughs
|
|
|
|
I never got the correct information working on the
|
|
[CWOP information page](https://weather.gladstonefamily.net/site/AV859) but I've
|
|
seen this page showing the correct information now. Also the map is now filled
|
|
with weather stations around my area (this has always been a place in the US
|
|
that I wasn't able to change).
