I have a Wemo Bridge for sale. Just plug this guy into a network port on your switch or router and plug its AC power adapter in. Then you can add the bridge to your Apple HomeKit from your iPhone or iPad, and it will let you add and control any Wemo wall switches or outlets you own from inside HomeKit. (Frees you from having to control them via the Wemo app, which only works when connected to wifi on your home network.)

It looks like the Apple Stores sell these now for $30 plus tax, if they have any in stock. But I'll let this one go for $20.
Located in Brunswick, MD but could meet an interested person in Frederick or possibly the Gaithersburg area during the week. Thanks!
