I read that IME needed an ethernet connection to power up your computer when it is off. It is not possible for it to turn power on over a powered down wifi adapter.

So you are probably OK overnight if not using a physical wired connection to the router.

I had not heard of any 3g or 4g capability of IME but I am by no means an expert on it. (Edit:- Seems I may be wrong but it may be Called ProV and AMT)

There is some power supplied over ethernet although I am not sure if IME can use this to run. You would be better using a wifi adapter or disconnecting the ethernet at night than the power in my understanding. Any air-gapped computer should be immune.
