use Weewx on raspberry

[Patrick Tranchant]

hello I am a newbie from France ( sorry for my english )

I want to use weewx on a raspberry with a weather station built by myself (view on Magpi)

I don't see my station on your website to configure :

Weather Station Hardware Comparison: I don't found my weather station.

Do you have a solution or how to configure Weewx

thank you for your help

Patrick

[rich T]

Patrick

We need additional information about the weather station you built.

Rich

[Patrick Tranchant]

hi

thank you for your response

follow this link , this is my weather station : https://projects.raspberrypi.org/en/projects/build-your-own-weather-station

patrick

[Patrick Tranchant]

it's me again

the communication between Weewx and my BYP weather station must be done with the GPIO of Raspberry

I think you know it.

Hello, Patrick

Je ne suis au courant d'aucun pilote périphérique pour WeeWX qui fonctionnerait avec la station météo "Build your own" Raspberry Pi que vous avez liée. Je ne trouve pas non plus de référence dans l'archive weewx-user.

Donc, vous devrez écrire le pilote !

Les instructions figurent dans le Customizing Guide, dans la section Porting to new hardware.

hello Thomas

General guidelines

• The driver should emit data as it receives it from the hardware (no caching).
• The driver should emit only data it receives from the hardware (no "filling in the gaps").
• The driver should not modify the data unless the modification is directly related to the hardware (e.g., decoding a hardware-specific sensor value).
• If the hardware flags "bad data", then the driver should emit a null value for that datum (Python None).
• The driver should not calculate any derived variables (such as dewpoint). The service StdWXService will do that.
• However, if the hardware emits a derived variable, then the driver should emit it.

whaouh
I'm not a developer, let alone a programmer

It is going to be difficult for me

Sorry. There is no driver available.

If you don't want to try to write a driver, another option might be:

Weather Station > Node Red > MQTT > Weewx

1. Your weather station interfaces Node Red via the Raspberry GPIOs.

2. Add the data to MQTT broker. (there is some programming that needs to done to get and add the data)

3. Using the Weewx MQTT extension, subscribe to broker. (there is some configuring that needs to be done)

[Patrick Tranchant]

thank you Rich

I go to try to read your solution.

[Pat]

Have you built the weather station yet? Is it giving you a reading of the sensors?

[Patrick Tranchant]

hello Pat

I have already my BYO weather station, it works good

it displays the data from sensors , they are stocked in MariaDB

the datas are display just in text mode.

thanks

How do you run the weather station? What file do you run? log_all_sensors.py?

[Patrick Tranchant]

I use a script on python3

I follow this link for the built of my weather Station

I can give you the final script

I followed your link, which brought me to GitHub. There are a lot of scripts there. 

If you can share your python3 script that will help. 

[Patrick Tranchant]

ok I give you the scripts

in attach file

The main script is weather_station_BYO_10.py

thank you

Thanks. 

Where do you plan to run WeeWX? 

on the same Raspberry Pi?

[Patrick Tranchant]

yes on the same PI

If you want to use WeeWX, we will have to convert this python3 script into a weewx driver. 

Then you would let WeeWX handle everything and you would get updates on a website. 

[Patrick Tranchant]

Yes

on the same raspberry

Writing a driver isn't a fast process and takes a lot of testing. I don't have your weather station so it might take a while to get it accurate. 

I don't have a lot of time left for today and won't be available tomorrow, but I can try an initial attempt. Unless someone else reading this wants to try it out too :) 

[Patrick Tranchant]

thanks to you

I can wait for you or someone other

have a good evening

Can you explain the difference between Ground Temperature and Ambient Temperature with this station?

[Patrick Tranchant]

the ground temperature (in french temperature du sol)  is with a DS18b2 sensor and the Ambient teperature is with BME280 sensor ( in french temperature de l'air)

[Pat]

Ok, so Ambient Temperature would be the outTemp observation. 

Is your DS18b2 in the soil? 

[Patrick Tranchant]

Yes it is good

[Pat]

I do not have this weather station so I have copied and pasted your python3 file to a format that WeeWX should understand. There will be bugs since I have no way to test it :)

I invite others lurking here to review and update anything obvious as well - for sanity's sake. I've commented the code with some questions which input from others here could be valuable in finishing the driver. 

To install: 

1. Copy the attached byows.py to your bin/user folder
   
2. Copy the dependency files from your python folder to bin/user otherwise the script won't start.
1. Such as wind_direction_byo_5.py, and any bme280 files. 
3. Copy this section to the bottom of weewx.conf. (there are no driver options yet, that might come in future) - I named it BYOWS for "Bring Your Own Weather Station"

[BYOWS]
    # This section is for the Raspberry Pi Bring Your Own Weather Station driver.
       
    # The driver to use
    driver = user.byows

Restart weewx

Check syslog with sudo tail -f /var/log/syslog -n 100 and see what errors come up and paste them here. 

[Patrick Tranchant]

hello Pat

you worked that night, where then you live on the other side of the atlantic with jetlag ..
Should I first install Weewx and what should I choose for the hardware to install?
thanks again

Patrick

[Pat]

Yes install WeeWX. If you're using Raspbian on your Raspberry Pi, follow these instructions. 

Select Simulator for the hardware during setup. 

Then copy the file above to bin/user (which is /usr/share/weewx/user if you installed by apt). 

Then run sudo service weewx stop

Then go to /etc/weewx and edit weewx.conf and add that code block to the bottom of the file

Then run sudo service weewx start 

Check syslog for what errors come up

[Patrick Tranchant]

hello Pat

how are you

My actual files ( weather_station_BYO_10.py) is installed in /home/pi/weather-station/

I put your file "byows.py" in the same directory; it is OK ?

And I run the file by python3 byows.py

1st error:

 python3 byows.py
  File "byows.py", line 104
    global self.wind_count
               ^
SyntaxError: invalid syntax

but maybe I'm wrong, it's the application "Weewx" by the web server that launches the file "byows.py" and not as I do, in any case the application by: http / localhost / weewx / gets off to a good start, but it's simulator mode data

I modified the file as:

 def reset_wind(self):
        self.wind_count
        self.wind_count = 0

I run again the file and 2nd error:

python3 byows.py
Traceback (most recent call last):
  File "byows.py", line 22, in <module>
    import weedb
ImportError: No module named 'weedb'

but maybe I'm wrong, it's the application "Weewx" by the web server that launches the file "byows.py" and not as I do, in any case the application by: http / localhost / weewx / gets off to a good start, but it's simulator mode data

watch the log:

[Pat]

Correct, you do not run the python file. 

You let weewx run it and control it. 

Did you add this to weewx.conf? And restart weewx.conf?

[BYOWS]
    # This section is for the Raspberry Pi Bring Your Own Weather Station driver.
       
    # The driver to use

    driver = user.meteostick_socket

You also need to change this line in weewx.conf. 

Under [Station]

    station_type = BYOWS

Then restart weewx again

In the syslog, you should see it say

engine: Loading station type BYOWS (weewx.user.byows)

[Pat]

I was afraid of that. 

How did you install gpiozero? I don't see it in the tutorial.

Try sudo pip install gpiozero and then restart weewx and check syslog again.

[Patrick Tranchant]

hi

!!!

pi@raspberrypi:~/weather-station $ sudo pip3 install gpiozero
Requirement already satisfied: gpiozero in /usr/lib/python3/dist-packages

problem with version of python ???

[Patrick Tranchant]

hi

just for information, my original file " weather_station_BYO_10.py" works very good and use GPIOZERO

patrick

[Pat]

Run this

sudo apt-get install python python-dev python-pip

Then run the python pip install gpiozero

Then restart weewx

[Patrick Tranchant]

 hello Pat
did you see my two previous answers?
GPIOZERO is well installed and I use pip3 and python3
should I still?

[Pat]

Yes but weewx uses python 2. You need pip2 to install

[Patrick Tranchant]

I can install Python 2 and python3 at the same time ?

Patrick

[Patrick Tranchant]

install pip2 for gpiozero

sudo pip2 install gpiozero

[Pat]

We are making progress. Your gpiozero is installed. Now we need to install the bme280 library. 

sudo pip install RPi.bme280

Restart weewx when done and paste the output of syslog

[Patrick Tranchant]

hi,

I installed :

sudo pip2 install RPi.bme280

[Pat]

Anything in the syslog as to what the error is? 

If you think it's the RPi.bme280 you can run sudo pip2 uninstall RPi.bme280 and that should remove it. 

But without that you won't be able to use weewx with your bme280 sensor. Or we'll have to find another driver like this one https://github.com/adafruit/Adafruit_Python_BME280

[Patrick Tranchant]

hello Pat

how are you ?

I found maybe the problem

I must unplug the BME280 module

watch the log, I didn't found anything

With the command : tail -f /var/log/syslog -n 100

[Patrick Tranchant]

hi

I uninstall pip2 RPi.bme280

I see on website Adafruit

[The default python on your computer may not be python 3. Python 2 is officially discontinued and all our libraries are Python 3 only.

We'll be using python3 and pip3 in our commands, use those versions of python and pip to make sure you're using 3 and not 2]

I don't have an adafruit.bme280but compatible, it is ok with my old script.

I don't know what to do.....

patrick

[Pat]

The BME280 can only be open at a time once. 

You must close your other script. 

Is weather_station_BYO_10.py running when you try to run weewx and reboot?

If so stop it and try again

[Patrick Tranchant]

yes the script weather_station_BYO_10.py is stopped

I run it just for test and after I stopped it

patrick

[Pat]

Ok get your Raspberry Pi back to a working state. Remove the python2 package. 

We will try another way

[rich T]

Patrick

Is this the BME280 python package you are using?  It works with python 2 and python 3.

problem with the path !!!

[vk3...@gmail.com]

You need to make sure that the weewx bin directory is in the PYTHONPATH.

I've just run weewx from python, but something like 

$ PYTHONPATH=/home/weewx/bin thonny......

- Use whatever the location of weewx is and whatever command you use to invoke thonny.

 hello PAT

I could install weewx on new RPi

Watch the new error:

I could test avec "Simulator" and after I modified the file to use "byows driver" as the other RPi.

on this RPI, I have just install Apache2, I think that I must install also Mysql . Yes or No

Patrick

[Pat]

Sorry, my time has been short lately. I am hoping someone else can jump in and help finish this. 

For this error try running sudo pip install statistics

Again, I don't think you can run your script and weewx at the same time. 

It will be one or the other. 

[Patrick Tranchant]

no problem, I was also in Holidays in ROME.

I could install Statistics and new  Error:

[Pat]

Did you add the test byows.py file to your bin/user folder?

[Patrick Tranchant]

hello PAT,

yes I think, I join the files weewx.conf and byows.py that I use

Patrick

[Pat]

Can you paste the directory listing for your user/bin folder? 

[Pat]

Correction, I meant to say bin/user folder. 

[Pat]

Also try changing this in weewx.conf to driver = user.BYOWS using capitals instead.

I have installed Weewx by the command : apt-get install weewx, I can remove and use other ?

[Pat]

That install method is supported. 

Everything so far seems OK and I'm not able to replicate this error since I don't have the hardware.

What happens if you type sudo weewxd /etc/weewx/weewx.conf ?

[gjr80]

user.BYOWS and user.byows are two different things. You have been using user.BYOWS in weewx.conf yet you have a file user/byows.py. Try using user.byows in weewx.conf.

Gary

[Pat]

With a new install using apt-get, I was able to get the driver to run with this config. 

I don't have the hardware so nothing happens.

hello Gary and PAT, HNY 2019

I could reinstalled with the other method, but I have the same error, look, and here is the conf, is the error not in byows.py (with capital or lowercase) ... ..

[Patrick Tranchant]

in my original file, there is:

def spin():
    global wind_count
    wind_count = wind_count + 1
   

maybe it's missing in "byows.py"? I do not know

[Pat]

Try this version of byows.py - copy to bin/user and restart weewx.

I do it, but this the same ERROR

Is your weewx Pi available externally? If I find a few minutes later I could try to SSH to it?

[Patrick Tranchant]

ok

I go to configure a DMZ and I come back to you, by private mail if possible

patrick

[Patrick Tranchant]

I am ready Pat

[Pat O'Brien]

Yes you can send me a private mail. I can't look at it for a few hours. Maybe you can leave it there for a day or so? Send me a login and your home ip in private mail.

In this case the problem is your code is trying use a BYOWS object before the BYOWS class has been defined. You need to re-structure your code to avoid calling the class before it is defined.

Exactly correct. I'm SSH'd to his Pi and debugging now. Will probably need more help soon but for now the driver is at least working. Unsure on validity of sensor values quite yet.

I've actually run out of time for today. 

Gary, I could use some help if you (or anyone else) has some time. I haven't done much special on the driver other than try to bolt everything together from the Tutorial's code and some of Patrick's code provided in this thread. Since I don't have the hardware it's a logical first step to me. 

In bolting things together it's making calls to other files which seems a bit sloppy for a driver. Perhaps there's a quick way to clean this up and consolidate? 

Secondly, in the genPackets function, there's a while loop which is counting the wind speed from the wind_direction_byo_5.py file and it delays things for roughly 60 seconds in 5 second intervals. Seems like there could be a better way to let weewx handle the wind speed counter?

This is where some of my inexperience with driver making starts to show up with wind speed counting and rain bucket tip counting. :)

Help is appreciated to try and finish this driver. 

Thanks

Hello Pat and Gary

I have reinstall on a new SD card Weewx with Apt-get install, that works good ( so as yesterday ).

that is a good thing.

Now, I installed also Mysql, I must to configure Mysql and no Sqlite3, I think , it is best, Yes

Say me

Patrick,

If you are struggling to get something working with weeWX then you are best advised to stick with SQLite. It is simple to use and easy to manage and just works. Setting up MySQL just adds more complexity, something you generally don't want if you are debugging other issues. In most cases unless you have a specific reason you are best served sticking with SQLite. The recommended approach is to get a stable functioning weeWX install and then migrate to MySQL if you wish to go down that path. That being said if you have installed MySQL /MariaDB and have it working without error then leave it be.

Happy to help where/when I can though I have none of this hardware so that limits advice to reviewing code/errors.

hello Gary

I prefer to use Mysql, because I installed already Nagios, Cacti, Zoneminder with Mysql, I know a little bit Mysql;

Is the config de Mysql inside Weewx.conf ? and in an other file ?

say me, thanks

[Patrick Tranchant]

Again Gary;

for the others values, Must I to modify the weewx.conf file ?  or just for config Mysql,

All is done inside the driver ?

[Pat]

If you want to use MySQL, follow the instructions in the weewx user's guide. 

[gjr80]

Patrick,

No problems. As far as weeWX is concerned all of the MySQL config information is located in the [DatabaseTypes], [Databases] and [DataBindings] stanazas in weewx.conf. Chances are they are already pre-configured with most of what you want. I strongly suggest you read the Configuring MySQL section in the User's Guide (http://weewx.com/docs/usersguide.htm#configuring_mysql)

Gary
