Unfortunately, the driver does not let you set the baudrate from the
configuration file. If you want to change it, you'll have to go into the
code. If you want to do this, starting at line 94 of weewx/driver/wmr9x8.py
you'll find this:
self.serialconfig = {
"bytesize": serial.EIGHTBITS,
"parity": serial.PARITY_NONE,
"stopbits": serial.STOPBITS_ONE,
"timeout": None,
"rtscts": 1
}
Just add baudrate so it looks like this:
self.serialconfig = {
"bytesize": serial.EIGHTBITS,
"parity": serial.PARITY_NONE,
"stopbits": serial.STOPBITS_ONE,
"timeout": None,
"rtscts": 1,
"baudrate" : 4800
}
If that works for you, I'll add the ability to change baudrate through
weewx.conf.
