Thanks. In the end I kept the sensor name the same and mimiced the code for
parse_json() from another posting so its compatible with both versions of
rtl_433.
NB original version of sdr.py parses battery status the wrong way round (0
is False, 1 is True). Seems to be a common problem in lots of sensors.
Here is the fixed code:
# {"time" : "2018-08-04 15:29:27", "brand" : "OS", "model" : "PCR800",
"id" : 236, "channel" : 0, "battery" : "OK", "rain_rate" : 0.000,
"rain_total" : 109.594}
# {"time" : "2020-05-23 11:18:53", "brand" : "OS", "model" :
"Oregon-PCR800", "id" : 40, "channel" : 0, "battery_ok" : 1,
"rain_rate_in_h" : 0.000, "rain_in" : 97.571}
@staticmethod
def parse_json(obj):
pkt = dict()
pkt['dateTime'] = Packet.parse_time(obj.get('time'))
pkt['usUnits'] = weewx.US
pkt['house_code'] = obj.get('id')
pkt['channel'] = obj.get('channel')
if 'battery' in obj:
pkt['battery'] = 1 if obj.get('battery') == 'OK' else 0
if 'battery_ok' in obj:
pkt['battery'] = 1 if obj.get('battery_ok') == 'OK' else 0
# Rain rate (inches/hour - weewx.us set above)
if 'rain_rate' in obj:
pkt['rain_rate'] = Packet.get_float(obj, 'rain_rate')
if 'rain_rate_in_h' in obj:
pkt['rain_rate'] = Packet.get_float(obj, 'rain_rate_in_h')
# Total rainfall (inches)
if 'rain' in obj:
pkt['rain'] = Packet.get_float(obj, 'rain')
if 'rain_in' in obj:
pkt['rain'] = Packet.get_float(obj, 'rain_in')
return OS.insert_ids(pkt, OSPCR800Packet.__name__)
Looking at the code for rtl_433 lots of other sensors are affected by the
cnages in rtl_443. Is there a mechanism for asking the developers to update
the official version of sdr.py?
Many thanks
