Hub 5 started beeping at night
So upgraded to hub 5 about 2 weeks ago. Initially everything was fine - technically it still is other than 1 small issue, around midnight it starts beeping, 3 quick beeps in succession then stops for maybe 3 seconds then 3 beeps. This goes on and on. I don't know what time it stopped since I went to bed at 430am but it was still going then. It doesn't beep during the day - or I'd say it just needs resetting or something. It's only at night. The light stays solid white too so it's not a connection or update issue. Any ideas? The beeping is quite piercing though not overly loud it's very annoying.
