With the MAX! system, you can bring your heating into the Internet age. The MAX! system offers various functions: controlling the ambient temperature via app remotely while being on the move, setting up heating programs with just a mouse-click or switching the entire house into eco mode at only the push of a button with the MAX! Eco Switch. MAX! users benefit from a coordinated system with different components that enable efficient energy management. The electronic wireless radiator and wall thermostats control the existing radiators and the window sensors help to save on energy costs as they put the system into energy saving mode during ventilation. You can control and set up the system with the MAX! Cube (the LAN gateway) via a PC or Internet connection or with the app via an encrypted and secured communication channel.

With the MAX! app you can directly control the temperature in single rooms or the entire house and execute your individual week programs. You will automatically be informed about the single device states. This information includes the current setpoint temperature, the state of single windows and batteries as well as any communication errors within the wireless system.

This app falls over more times than horses in the Grand National. Totally unstable. Works when it feels like it which is sometimes never.

Excellent devices, shame about the App

I've got the Cube. Every radiator has a thermostat valve attached. The house has 9 wall thermostat's installed. Everything has been setup and structured using a PC. The info displayed on the PC is great. It's functionality is brilliant. BUT THE APP JUST PLAYS DEAD. I don't have any German language skills. I'M THWARTED.

Good easy to use app and is also in English,

Was worried when buying these devices that the app would be in German but the words/labels I could see are English so no issues there!

Good app and allows full degree of control at zone/room and house level. Slight delay in refreshing temp data when you first open it (no status/icon to say that it is downloading this) but once it has sync'd then you are good to go.

One enhancement that would be nice is a historical view/graph of "set" vs "actual" temperature over the past 24hrs/7days for each zone.
