Why do I see two apps from Duux in the app store? 

Currently there are two versions of the Duux app available; Duux (Gen 1) and Duux app. Starting this fall, our electric heaters will come with a new WiFi module that is only compatible with the Duux app. Through this link you can easily enter the serial number of your Duux device, so you know immediately which app is suitable for your product. You need to enter your full serial number to get a result.
