All lights turn on with no commands issued or automations run

I'm encounting a very strange issue with my HA installation. At ~12:45 AM each night, all the lights in the house turn on, and one minute later, they all turn back off. if I check the logbook, it shows they were triggered by Home Assistant Cloud, but that part seems to be triggered by Alexa. I don't have anything timed for that period in Alexa, in fact I'm not using anything time based for Alexa at all.

I've also checked the Alexa logs, no voice commands nor routines are run during that time. It is also not every night, but it has happened a few nights in a row. I did suspect this might have been an issue with a state push to Alexa where things were getting out of sync, but even with that disabled it is still happening on occassion.

Any educated guesses as to what is triggering this?

Have you checked Alexa "Hunches"?

I'll double check but I didn't think I saw she activated any hunches

Also, not sure why that'd cycle them on and then back off.

No kids. And as far as I am aware the dog cannot speak.

So after some poking around in Hunches, there were no hunches to turn the light ON, but there were a ton turning the lights off. Which makes me think Alexa just did "toggle" rather that a discrete "off".

So far, so good.
