Hi. From time to time, it seems like my GW1000 disappears. It looks like
the code is trying to rediscover it, but in the process hits a bug in the
code and crashes. This is with weewx 4.5.1 with python 3.7.3 and GW1000
0.41. The syslog looks like:
Mar 15 04:14:45 raspberrypi weewx[1374] ERROR user.gw1000: Failed to obtain

TypeError: not enough arguments for format string
I *think* the bug is on line 3928 in rediscover(self):
gw1000_str = ', '.join([':'.join(['%s:%d' % b]) for b in device_list])
This looks like a copy of the similar line further up in the code where the
GW1000 is first discovered. I'm a complete python newbie, but it looks
like the second join in the above line wants two fields but is only getting
one. Shouldn't it be ".join(['%s' % (b['ip_address'],b['port'])])"?
That's the way the first version of gw1000_str is formed.
Cheers,
Bob Clare
