This is a set of two SwitchBo Plug Mini smart plugs. It's a model that also supports Apple HomeKit★ Recommended for iPhone users. You can turn them on and off at specific times on specific days, use the button to turn them on and have them automatically turn off after a set timer, and control them with Alexa or Siri. These are very convenient smart plugs★ You can use them without the included QR code card, but it's helpful for setup, especially when installing them in tight spaces. There are some faint marks on the included card where I had written notes, but the writing is mostly gone. The plugs themselves are in good condition★ I will pack them carefully and ship them★
