How to control several rooms' temperature by one-key?

Sometimes, we don't want to open the room temperature controller one by one. Is there any way to control the temperature of all rooms by one-key? The answer is yes, Several thermostats can be controlled by one smart phone or tablet. If you would like to adjust the temperature of several rooms at the same time, just set up a group for these rooms in your APP.  For rooms have similar functions, group control is a great choice.
