Weewx Version: 5.0.2-1 issues post upgrade

[meteo219]

Hello Weewx Users,

I upgraded weewx tonight on my raspberry pi to version 5.0.2-1 and since doing so, I had some major reconfiguration issues to get things working again.  I upgraded via apt upgrade -y and then choose Y when asked if I wanted to upgrade weewx.conf.  I am thinking that I should have gone with the default of N there.

That said, I was able to fix most things myself by following instructions I found here:

https://github.com/weewx/weewx/wiki/Understanding-permissions#the-weewx-user

I am using SDR for most of my data and BME280 for pressure.

The code that I am using for those products in /etc/weewx.conf looks like this:

[SDR]
    # This section is for the software-defined radio driver.

    # The driver to use
    driver = user.sdr

    cmd = /usr/bin/rtl_433 -M utc -F json -R 40

    [[sensor_map]]
        outTemp = temperature.04A5.Acurite5n1PacketV2
        outHumidity = humidity.04A5.Acurite5n1PacketV2
        windDir = wind_dir.04A5.Acurite5n1PacketV2
        windSpeed = wind_speed.04A5.Acurite5n1PacketV2
        rain_total = rain_total.04A5.Acurite5n1PacketV2

[Bme280wx]
    i2c_port = 1
    i2c_address = 0x77
    usUnits = US
    temperatureKeys = inTemp
    temperature_must_have = ""
    pressureKeys = pressure
    pressure_must_have = outTemp
    humidityKeys = inHumidity
    humidity_must_have = ""

I already installed modules using apt:

apt install python3-smbus2

apt install python3-bme280

That said, I am not seeing any pressure data from bme280.  I ran weectl extension install  bme280wx-master.zip and that added under [[Services]] this line:

data_services = user.bme280wx.Bme280wx

When I restart weewx, I see these errors with debug on:

2024-02-22T01:52:50.936407-05:00  weewxd[11578]: CRITICAL __main__:     ****    File "/etc/weewx/bin/user/bme280wx.py", line 58, in __init__

Line 58 of the above file is: self.bus = smbus2.SMBus(self.port) if that helps.

Any ideas on this one?  Things were working great before this upgrade.  I am thinking that I need an updated version of the bme280 script but not sure what is wrong.

Thanks,

Jeff

Hello Jeff,

For having my BME280 working properly with Weewx 5.0.2.1, I had to add this permission: "sudo usermod -aG i2c weewx".

Did you add it already ?

Hi Pierre-Yves,

Thanks for the suggestion, I just ran that command, uninstalled the extension and reinstalled it.  Unfortunately, either it didn't help or I am seeing new issues.  Here are the new errors I am seeing when installing the bme280wx-master.zip extension:

This may or may not be helpful, but when I try to run the python extension: bme280wx.py from a command line, I am getting these errors:

/etc/weewx/bin/user#python3 bme280wx.py

  File "/etc/weewx/bin/user/bme280wx.py", line 8, in <module>
    import weewx
ModuleNotFoundError: No module named 'weewx'

Please note, when I uninstall the above extension, weewx works fine without the pressure data.

Thanks again in advance!

Jeff

I fixed my issue today by modifying the bme280wx-master/install.py script to use the correct i2c_address: 'i2c_address': '0x77'.  It was set to 0x76.  I then uninstalled the extension and reinstalled it.

Thanks again!

I read this on your log: OSError: "[Errno 121] Remote I/O error"...

Prior installing the BME280 extension, I installed the AS3935 one and I had also to add gpio to weewx group to make my AS3935 lightining detector working.

Maybe try this: "sudo usermod -a -G gpio weewx"

[Pierre-Yves]

Ok Jeff nice. Sure, it couldn't work with a bad i2c address ;-)
