I have done this as well, it definitely helps you sleep better. It also prevents work from intruding on personal time, as long as you're not on call--just leave the work device at home.

It's also worthwhile to set up a separate home LAN for work stuff. This not only protects you, but it also ensures that work data is kept away from roommates, guests, etc. Prosumer-level routers and access points like Ubiquiti can broadcast multiple SSIDs and tag traffic on each with a different VLAN. Not at all hard to set up and definitely worth the peace of mind.
