If you are only running 4K Watts or so and not living there, not sleeping, watching TV and lights thruout the house all the time, it should appear as a steady normal household bill.

The only thing that I would be concerned about, it the timers.

Going from nothing to full blown power usage at the exact same times everyday . every night...could be suspect.

But then, I dont think your electric company sits and monitors what time your lights go on.

If you kept it to minimal, the other items that use electricity, you;ll be fine.
