I may have to unplug my pi and move it to another part of the house. What happens to the download of the blockchain? Will it update when I plug it back in?
You can move it without problem, just be sure to properly shutdown it via the interface (Settings > Shutdown) before pulling the power.
Just to add, when shut down you will miss all the blocks that confirm while down. These will resume downloading as soon as the node is powered up. If your down for hours you won’t even notice it. If your down for months then you’ll see a bit of time to synchronize. Still no big deal.
