Yes. Two methods come to mind:
1. You can suppress the debug messages in the driver. See Throttling
logging events
<https://github.com/weewx/weewx/wiki/WeeWX-v4-and-logging#throttling-logging-events>
.
2. Or, you can add a [Logging] section to weewx.conf to do the same.
[Logging]
[[loggers]]
[[[weewx.drivers.pymodbus]]]
level = INFO
Once we get the hang of it, I think we'll find the Python logging module
much more flexible. See the white paper Weewx V4 and logging
<https://github.com/weewx/weewx/wiki/WeeWX-v4-and-logging> for details.
