// You can get HomeSeer Device References by clicking a HomeSeer device name, then 
// choosing the Advanced Tab.
//
// The uuid_base parameter is valid for all events and accessories. 
// If you set this parameter to some unique identifier, the HomeKit accessory ID will be based on uuid_base instead of the accessory name.
// It is then easier to change the accessory name without messing the HomeKit database.
//
