ROCCAT™ Power-Grid™ is an advanced and fully-customizable remote control for your PC. It lets you connect to, monitor, and control your PC and games directly from your smartphone – and all without having to leave the action. Best of all: it’s totally free to get started.
To run Power-Grid you need to download and install two components: the host software and the mobile app. The host software is the engine of Power-Grid –the part that does all the work. It processes and renders everything before relaying it to the mobile app, so it’s important to install it part first. You can find the download links for iOS et Android here http://power-grid.roccat.org/en/Download/
