Last year Target unveiled its Internet of Things "Open House" experiment in San Francisco. The goal was to create a shopping experience that would help customers figure out how connected devices work with each other. In the confusing and fragmented world of IoT, the retailer carved out a little corner of knowledge. Now it's moving past the testing phase and opening a "connected living experience" in a suburban Minneapolis store. The Minneapolis setup won't be as elaborate as Open House in San Francisco with its touchscreen tables. Instead it will have large displays above the products that explain how a gadget interacts with other devices. Target will also make sure the staff is up to speed.
