Xiaomi Gateway Flashing Red?

[Technotron]

When I came downstairs this morning, I realized one of my Gateways had been flashing red all night from the moment arming became active. I could verify this on my Dafang security camera footage. No alarm went off last night though. Even now I am getting a message notification inside the MiHome app every couple of minutes, but there is no actual message in it.

Any thoughts? I haven't changed anything in my Smart Home setup in weeks and it's all been working just fine up until last night.
