Think of this as being a "camping out" period - you're not entirely moved out, and you're not entirely moved in.
Play a game (for your sake, if for no one else) of "Let's Do Things Differently!"...
"Kids, the machinery is packed away. If you need something at night, you know where I am - upstairs, where I've always been! If one of you feels sick, wake up the other one and have him/her take a message to me. Here's a flashlight if you need it. I don't think you will need anything, though. And, just to be fair about it, if I feel sick at night, I'll send a message to you. OK?"
They may laugh at that. This would be a good thing. The worst thing that is likely to happen is that they'll enjoy the flashlight and wake you up just for fun.
My (adult) kids use monitors for their children when they travel (our sleeping arrangements are different from the arrangements at their house), and also sometimes at their home. It's interesting, because their children are old enough now to have conversations with Mama and Daddy over the baby monitor. "Mommmmy, can I get up yet?"
All things considered, your children are healthy and not likely to be kidnapped from their beds. They know you love them and are there for them. They know how to get your attention when they want/need it, right? So make this period an adventure. When you do complete your move, you may find that you don't need the monitors except in the event of serious illness - and they might be happy to be without them.
I don't want to be critical of you. When I read your post, I'm reading about a mother who cares about her children. And that's wonderful.
