I know enough just to screw things up, so I'm probably wrong, and I have
not updated sdr_433, but
I just looked through sdr.py, and, for the 5n1 sensor, the parse_text
method has both "wind_speed" and "wind_speed_mph", but the parse_json
method, which is decoding msg_type 49, does not.
I am not a programmer, but I bet adding it to this section of sdr.py would
do the trick. It couldn't hurt much, anyway.
if msg_type == 49: # 0x31
pkt['wind_speed'] = Packet.get_float(obj, 'wind_speed') # mph?
pkt['wind_dir'] = Packet.get_float(obj, 'wind_dir_deg')
pkt['rain_counter'] = Packet.get_int(obj, 'raincounter_raw')
pkt['wind_speed_mph'] = Packet.get_float(obj, 'wind_speed_mph')
