This allows you to connect your base to the Ergomotion power app which through your Wifi, let’s you connect your bed to your smart phone (apple or android) and have access to additional zero gravity, massage timer, and extra presets through the Ergomotion app. This will only work with the new generation Motion Essentials four and Beautyrest advance motion base with a keeson control box. We link a picture of the remotes for clarity but the remote is sold separately. You also will have access to Alexa or Google home smart voice features but in our experience the app for voice control is still under development and can make the bridge loose connection so we just recommend the app features and to always have a physical remote as well.
