Parser for Oregon Scientific UVR128

[sirrated]

First off, thank you for making this WeeWx driver available!

Can some kind soul write a parser for the Oregon Scientific UVR128 UV Index sensor? RTL_433 added support in 2018. Here is the output:

out: ['{"time" : "2019-11-05 07:07:07", "model" : "Oregon Scientific UVR128", "id" : 116, "uv" : 0, "battery" : "OK"}\n']

Thank you!

I made an attempt to write my own parser, based on similar parsers already in sdr.py:

class OSUVR128Packet(Packet):
    # 2019-11-05 07:07:07 : Oregon Scientific UVR128
    # House Code: 116
    # UV Index: 0
    # Battery: OK

    IDENTIFIER = "Oregon Scientific UVR128"
    PARSEINFO = {
        'House Code': ['house_code', None, lambda x: int(x)],
        'UV Index':
            ['uv_index', re.compile('([\d.-]+) C'), lambda x : float(x)],
        'Battery': ['battery', None, lambda x: 0 if x == 'OK' else 1]}

    @staticmethod
    def parse_text(ts, payload, lines):
        pkt = dict()
        pkt['dateTime'] = ts
        pkt['usUnits'] = weewx.METRIC
        pkt.update(Packet.parse_lines(lines, OSUVR128Packet.PARSEINFO))
        return OS.insert_ids(pkt, OSUVR128Packet.__name__)

        # {"time" : "2019-11-19 06:44:53", "model" : "Oregon Scientific UVR128", "id" : 116, "uv" : 0, "battery" : "OK"}

    @staticmethod
    def parse_json(obj):
        pkt = dict()
        pkt['dateTime'] = Packet.parse_time(obj.get('time'))
        pkt['usUnits'] = weewx.METRIC
        pkt['house_code'] = obj.get('id')
        pkt['uv_index'] = Packet.get_float(obj, 'uv')
        pkt['battery'] = 0 if obj.get('battery') == 'OK' else 1
        return OS.insert_ids(pkt, OSUVR128Packet.__name__)

It appears to be working:

out: ['{"time" : "2019-11-19 07:21:23", "model" : "Oregon Scientific UVR128", "id" : 116, "uv" : 0, "battery" : "OK"}\n']
parsed: {'uv_index.0:116.OSUVR128Packet': 0.0, 'battery.0:116.OSUVR128Packet': 0, 'usUnits': 16, 'dateTime': 1574148083}

If you attempt writing your own parser, don't forget to add the new class to the KNOWN_PACKETS list. :) I'm still new to GitHub so I'm still trying to figure out how to contribute.

I created a fork with changes to sdr.py to add the UVR128 parser. I plan to give it another week of testing before creating a pull request.
