RN104 automatically powering on (you are not alone)
RN104-Gumboe also reported this problem as posted here on 2020-5-23 however was never resolved. I've had this same problem for many years, I think I noticed it soon after purchasing the RN104 in Dec ...

My RN102 turns on about once a month on its own - the last two times were 2 May and 1 April this year. Its running 6.10.4 firmware.
There's no obvious cause, but I haven't looked that extensively into it either. I just power it down again. I think it must be something scheduled in the bios/uefi, and I don't know of any way to query that in a booted system.
A workaround is to schedule power down (as an event) regularly, so it doesn't stay up too long when it does occur.
A "brown out" may be more likely to cause this than full power loss. There is a separate power source (3.3VSB) in the NAS that powers the NIC and power-on circuits. If it were to drop below some threshold but not low enough for a proper reset of the circuit and return to full level, it might cause the power on to falsely trigger. If the NAS is on an UPS, then that's likely not it unless the power brick itself is misbehaving. I have a 102 and 212 that do not exhibit this behavior. They are on an UPS.
Unlikely due to brown out as it sits under the TV and I saw it turn on once but there wasn't a noticable brown out.
One other thing I can think of is overheating. The 3.3VSB is always on unless the NAS power supply is unplugged (or rear switch is off on units with an internal supply), so the voltage conversion, power on-off, and NIC circuits are always on but the fan is not. If under the TV means on a carpet, where heat from another device can raise the temperature, or just where there is poor air circulation without the fan, relocation may help. If that is the problem, then any of those cirrcuits may eventually fail from repeated overheating, so it's a bit more than an inconvenience.

FWIW, my RN102 isn't on an UPS. I don't think power is a likely cause though - the pattern seems much too regular for that.
Does your RN102 have a maintenance schedule set?
Does automatic OS updating include periodic power on to check for one? I don't use it, so I just don't know.
