[Per Edström]

During debug of sensors (DEBUG_.. = 1 in wmr200.py):

Sep 26 17:00:35 RPi-3Bp-Arelien weewx[3203] CRITICAL __main__: Caught unrecoverable exception:

Current code:

def decode_uvi(pkt, pkt_data):
    """Decode the uvi portion of a wmr200 packet."""
    try:
        record = {'uv': pkt_data[0 & 0x0f]}
        if DEBUG_PACKETS_UVI:
            log.debug("  UV index:%s\n" % record['UV'])
        return record

Suggested change:

def decode_uvi(pkt, pkt_data):
    """Decode the uvi portion of a wmr200 packet."""
    try:
        record = {'uv': pkt_data[0 & 0x0f]}
        if DEBUG_PACKETS_UVI:
            log.debug("  UV index:%s\n" % record['uv'])
        return record

You're on the right track, but the correct key is 'UV', nor 'uv'.

Oh, wait. Forgot about the sensor map. Your version is correct.
