Came home last night to a very dark house. Earlier in the day we had several short power outages, about 3-5 min. Additionally it must have done something to the cable internet in the area, as it was down for hours. The bridge, Mac mini are both on surge and UPS's and I did see they kept running.
Last night I could not get any response form Indigo via the Mac mini nor through the app. Internet was working when I got home. I used the Lutron app to get some light. Following morning, lights were off as they should have been via Indigo. All is well now.
I am attaching a log and the issues seem to start at the 14:00 hours.
