Read full description

The WebBox SKX_WEB is designed for easy control of all Tedsen K512 radio receivers (or compatible receivers) in the 434MHz frequency range. The SunTed WebBox can be easily operated remotely using this mobile app on a smartphone or tablet. This app is solely a remote control for a SunTed WebBox, and the connection is made via Wi-Fi or the internet. All WebBox settings must be configured beforehand as an administrator via browser access. Simply click on the house icon, which may be labeled as "Home" or "Haus," or it may contain the custom name you assigned to your home during setup. You will now see the folders and subfolders of your home, representing different floors and rooms, for example. When you click on a folder, you will see the devices contained within it for remote control. Click on a device, and a window will open, displaying the remote control buttons available for that device. When a control button is pressed, it changes color: Blue: The command has been transmitted to the SunTed WebBox. Green: The radio command has been sent. Red: The radio command could not be sent. Devices you frequently use with this app can be individually marked as "Favorites." All your favorites will appear in the middle tab with the star symbol. Favorites can be set separately for each iPhone/iPad. This allows each user to create their own set of favorites.

Start reducing your energy consumption with the Ynni app! First step is getting insight into your current consumption. Ynni splits your consumption into categories of appliances. This way you get a better understanding of where your energy is being consumed. By comparing the energy usage of a specific appliance with those of your peers you’ll see how much room there is for improvement. In case you have solar panels, Ynni provides you with a pretty good estimation of your solar production, and also shows you how much of your own solar energy is used by your household. Ynni provides actionable tips that fit your home characteristics and daily life, that helps you use your appliance in an efficient way. Ynni helps you identify where energy is being wasted by making consumption transparent, from turning down the heater, turning off electrical appliances which you don't really use, using your own solar energy more efficiently, replacing an old washing machine or insulating your house. Enjoy your Ynni app! The app works in combination with the SmartBridge WiFi dongle for your smart meter. Or via a data hub connection (EDSN).
