There is something not right in your configuration file.
In /etc/weewx/weewx.conf:
1. You should duplicate the block under [WMR300] and assign a new label
WMR300x, similar to this:
##############################################################################
[WMR300]
# This section is for WMR300 weather stations
# The station model, e.g., WMR300A
model = WMR300
# The driver to use:
#driver = weewx.drivers.wmr300
driver = user.wmr300-v19rc6+f3
history_limit = 6
debug_counts = 1
debug_decode = 0
debug_comm = 0
debug_history = 0
debug_timing = 1
debug_rain = 0
##############################################################################
[WMR300x]
# This section is for WMR300 weather stations. experimental driver
# The station model, e.g., WMR300A
model = WMR300x
# The driver to use:
driver = user.wmr300x-v19rc6+f3
history_limit = 6
debug_counts = 1
debug_decode = 0
debug_comm = 0
debug_history = 0
debug_timing = 1
debug_rain = 0
# Set debug_backend to 0 for default lib
# 1 for libusb0
# 2 for libusb1
# 3 for openusb
# 4 for ... depends on local pyusb
debug_backend = 0
##############################################################################
the "driver" line needs to point to the correct driver file location.
This makes it much clearer in the logs which driver is being used.
Then, to switch drivers, simply edit the "station_type" in the "[Station]"
block.
