I still have a lot of weirdness when it comes to making things actually stay asleep and wake up again when wanted. There's a lot of hardware that often boots up, or always boots but only if it's been switched on once before, or keeps trying to wake itself up for no good reason.

The absolute most consistent way I've found is using cheap zigbee smart switches or even second hand smart PDUs. Set the machine to boot when power is restored and actually switch the thing on and off from the wall. It saves a whole lot of messing around, you can force the reboot issue and for a tiny amount more in upfront costs you can have power monitoring as well. It also works for network gear that doesn't sleep or anything else that had a physical switch.

edit: Ideally give me hardware with proper out-of-band management (ipmi or AMT at a pinch), but for everything else having control of the power is as good as it gets.
