Had some alertt this morning that a network device was offline.
When I checked the Whole Home network I saw one disk (called "Bedroom") was disconnected and Red.
When I went to the disc itself it had a blue light (though See below as this might have been intermittent).
The troubleshooter advised restarting the network, which I did, and all was well.
Checking the logs the outage seesm to have statred with the following message logged on the main router connected disc (Study):
09.03.2018 06:02:06 [2 4 2] Firmware upgrade - FW SYNC compare WHWv1.02.04build10 WHWv1.02.04build10!
(I'm already on v1.02.04 build10 on all 3 discs)
And after that there's plenty of
09.03.2018 06:07:31 [2 4 2] OWL-Bedroom(48:8D:36:xx:xx:xx) leave topology
09.03.2018 06:07:45 [2 4 2] OWL-Bedroom(48:8D:36:xx:xx:xx) join topology
messages on the Study Log.
On the Bedroom disc just see quite a few:
09.03.2018 06:02:08 [2 4 2] OWL-Sync pollingconfig done.
09.03.2018 06:02:08 [2 4 2] OWL-Adjust LED from Bright to Bright.

09.03.2018 06:05:15 [2 4 2] OWL-Sync config success
Messages after that Firware item.
After network restart, the main (Study) and 3rd disc (Kitchen) show a short uptime, but the Bedroom disc (now connected) shows up for 6 days (so presumably it didn't get included in the restart).
Just posting in case it identifies a bug for future fixing.
