I am running Weewx 5.1 on an rpi 4 with a BYOWS driver. It crashes several times a day at random times (weewx process stops somehow), below is the log file of a time where it crashes. I have created a crontab task that starts Weewx every hour (in case it has crashed and starts again) and that works, but then gaps appear, I can create that task every 5 minutes, but would rather get rid of the source of the problems and I can't figure out what is not going right now. Can anyone help me?

This looks like a problem in the BYOS driver. It makes assumptions about how the weather station responds that are not true. For example, it may be trying to parse an empty line.

I would file a report with the driver's author.

This is the second time I make a BYOWS weather station, with the other I have no problems? Can I check if there a difference in the code in both stations? Wich files should I check than?

From your logs, I'd say you should check to see if /etc/weewx/bin/user/byows_rpi.py is the same on the two stations.

How did you solve it?

hello,

I didn't do anything special. Here is the config of weewx.conf

A few lines

weewx.conf

# This configuration file was created by ...
version = 5.1.0

# Set to type of station hardware. There must be a corresponding stanza
# in this file, which includes a value for the 'driver' option.
station_type = BYOWS

[BYOWS]
    # This section is for the Raspberry Pi Bring Your Own Weather Station drive>

    # The driver to use
    driver = user.byows

    # Loop Interval
    loop_interval = 2.5

    # Pin to which anemometer is connected, the DEFAULT is pin 5.
    anemometer_pin = 5

    # Pin to which rain bucket is connected, the DEFAULT is pin 6.
    rain_bucket_pin = 6

    # Port and address for sensor bme280, the DEFAULT are port=1 address=0x76
    bme280_port = 1
    bme280_address = 0x77

    # Channel to which wind vane is connected to on MCP3008, The DEFAULT is cha>
    mcp3008_channel = 0

    # Anemometer adjustment value, the DEFAULT is 1.18
    anemometer_adjustment = 1.18

    # Bucket Size in mm, the DEFAULT is 0.2794 mm.
    bucket_size = 0.2794

    # Anemometer radious in cm, the DEFAULT is 9.0 cm.
    anemometer_radius_cm = 9.0

and the location of the driver:
