I have been using the plugin for a while now an it worked with the following result in de log file:
2016-09-20 00:00:32.721 OWServer Getting OWServer data...
2016-09-20 00:00:33.001 OWServer Total of 1 servers polled.
2016-09-20 00:00:33.002 OWServer Total of 3 devices updated.
2016-09-20 00:00:33.002 OWServer OWServer data parsed successfully.
Today I found this message in my log:
2016-09-20 13:05:08.217 OWServer Getting OWServer data...
2016-09-20 13:05:23.223 OWServer Error Exception error getting server data: timed out
2016-09-20 13:05:23.244 OWServer Error Error parsing sensor states: Parse() argument 1 must be string or read-only buffer, not None

2016-09-20 13:05:23.247 OWServer Total of 0 servers polled.
2016-09-20 13:05:23.249 OWServer Total of 0 devices updated.
2016-09-20 13:05:23.251 OWServer OWServer data parsed successfully.
Not sure how but the IP address seemed to have changed. The IP address wasn't fixed in the router so I changed that. Secondly I changed the IP address of the OWserver plugin.
Now I am seeing the following in my log:
2016-09-20 16:07:23.154 OWServer Error OWServer hasn't been updated in 0:04:01.153000. If this condition persists, check it's connection.

2016-09-20 16:07:23.390 OWServer OWServer data parsed successfully.
or
2016-09-20 16:07:23.166 OWServer Getting OWServer data...
2016-09-20 16:07:23.388 OWServer Total of 0 servers polled.
2016-09-20 16:07:23.389 OWServer Total of 3 devices updated.
2016-09-20 16:07:23.390 OWServer OWServer data parsed successfully.
It seems that it is updating but it is saying 0 servers polled and sometime that the plugin hasn't been updated.
