The SGS1010 is an upgraded version of the Innohome heat sensor. It is smaller in size and the new design integrates even better into different kitchens. The battery is easy to replace. Simply remove the old Innohome heat sensor and installation plate and place the new one in its place. Then pair the SGS1010 with the Innohome control unit behind your stove to have them working as a Stove Guard and protecting you from stove fires.
