How do I disconnect my Sonos system for a long time lay-off? Three months.

If you are in an area subject to lightning strikes I’d also unplug any Ethernet cables from your router/switch and the devices they connect to.
When you come home power up your Internet and get it working. Then plug in one Sonos and let it boot up, power the rest up one at a time and you’ll avoid any issues that cold starts can cause.
Check for and apply updates to both the controller and devices and you should be working perfectly again.
