I recently added an outlet outside so we can install some new lights for decorations. One thing I purchased is a Smart Hubspace Outdoor 6-Outlet Power Stake from Home Depot. This thing uses HubSpace (I'm not a fan of wifi devices, Lutron is on backorder) and I found a plugin for Home Bridge that will let me control it with Homekit on my iPhone. Score.
