Hi,
Not a sdr driver or Acurite user but looking at the sdr driver as far as I
can tell the sdr driver expects Acurite5n1PacketV2 rain data to be in field
rain_mm whereas you appear to have rain_in. You could try adding the
following two highlighted lines to /usr/share/weewx/user/sdr.py:
if 'wind_dir_deg' in obj:
pkt['wind_dir'] = Packet.get_float(obj, 'wind_dir_deg')
if 'rain_mm' in obj:
pkt['rain_total'] = Packet.get_float(obj, 'rain_mm') / 25.4
if 'rain_in' in obj:
pkt['rain_total'] = Packet.get_float(obj, 'rain_in')
if 'temperature_F' in obj:
pkt['temperature'] = Packet.get_float(obj, 'temperature_F')
Save sdr.py then try running sdr.py directly again.
Oh, and of course, make sure you keep a back of sdr.py before making any
changes.
