Hi John,
Works great. Here is what I added to the loop-data.py
Line 735 self.ten_min_packets, self.cfg.ten_min_obstypes)
# Added to allow specific null keys if no data available in
loop packet
must_have_keys = [ 'current.dateTime',
'current.extraTemp1.raw', 'current.extraTemp2.raw',
'current.extraTemp3.raw', 'current.extraHumid1.raw',
'current.extraHumid2.raw', 'current.extraHumid3.raw' ]
for must_have_key in must_have_keys:
if must_have_key not in loopdata_pkt:
loopdata_pkt[must_have_key] = None
Thanks!
