weeWX Driver for Build Your Own Weather Station for Raspberry Pi
License: GNU General Public License v3.0
This is @jardiamj! 👋
Hi, I build a weather station using the Raspberry pi weather station guide, all is working perfectly with the python3 code: upload to weather underground, store data to SQLite, etc....
I use a Raspberry 3b equipped with a real clock an battery.
I follow your guide for the installation.
When I start weewx ``sudo weewxd /etc/weewx/weewx.conf`
The program stop`and /var/log/syslog look like that:

I reinstall all the library that I use with python3 with pip to have them with python 2.7, all my wiring is operational, I don't know what to do do now.
Thanks in advance for your time.
After downloading the driver into the /usr/share/weewx/user directory, the downloaded file is an html file with a first line of
Hi Jardi!
I appreciate your BYOWS_RPi driver , working with all sensors, but i would like to develop further.
Are there any solution to connect - to the BYOWS_RPi driver - other DIY sensors like sun radiation meter (tiny solar cell), dust and smoke sensor?
Best wishes,
Zoltan
Hi
Wind gust is left to weewx to handle (=average 5 minutes).
I don't know if I can get this into Your excellent driver by myself.
https://projects.raspberrypi.org/en/projects/build-your-own-weather-station/6 has a way.
Suggestions?

Hi! Thanks for writing this driver, it'll let me get a bargain-basement weather station online...once I get it working. ;)
For now all I have is a BME280, so in weewx.conf I have a sensors = bme280 line so that should be all it's trying to access. But weewx can't load the driver. The log has the following lines:
Apr 20 10:45:36 raspberrypi weewx[3240]: BYOWS RPi: driver version is 0.51
Apr 20 10:45:36 raspberrypi weewx[3240]: engine: Import of driver failed: pin 8 is already in use by SPI(port=0, device=0) (<class 'gpiozero.exc.GPIOPinInUse'>)
Apr 20 10:45:36 raspberrypi weewx[3240]: engine: Unable to load driver: pin 8 is already in use by SPI(port=0, device=0)
Apr 20 10:45:36 raspberrypi weewx[3240]: **** Exiting...
I'm not sure why it should even be trying to talk to SPI or GPIO pin 8, as the sensor is hooked up to I2C on GPIO2/3.
I've tried the bme280_sensor.py sample script from the raspberrypi.org build instructions and it works fine, so I know the sensor is ok and is talking to the pi over I2C.
I've also tried running "PYTHONPATH=/usr/share/weewx python /usr/share/weewx/user/byows_rpi.py" to test it outside of weewx and see if I got a more detailed error message but all I get is the following:

Not sure what I'm doing wrong here, can you please help? Let me know if there's any more info you might need from me. Thanks!
hey thanks for sharing your work!
I only connected the Davis Anemometer to the RPi4B Model and now it would be great to read out the wind data. Can you give me some advice on how to change your code according my setup?
Happy greetings
Paul
I have installed the byows driver on the latest version of weewx running buster on pi3b.
I have restarted the weewx service but when i load the web gui
It displays data from the simulator driver.
Is there something else i need to do?
I have made the BYOWS and now at step 9, but I think I can pass the Storing measurements in a database part in https://projects.raspberrypi.org/en/projects/build-your-own-weather-station/9?
I want to report alone into Weewx and in weewx, the data is stored in a weewx database i gues? Preventing storing same data into two databases? Am I correct?
Keep getting this error. Can you maybe have a look why ?

Can you make file BYOWS_RPi for upload data to Weather Underground ?
I tried many times to follow this project . I don't understand why i can't do it.
