Ridgeland’s C Spire plans to debut by the end of the year C Spire Home, a suite of home security/automation services for homeowners that can be monitored in or outside the home through a free app that can be downloaded onto mobile devices. Users can remotely control heating and cooling, lighting, door locks and home alarms and monitor carbon dioxide levels. The service initially will be available only to the carrier’s Fiber To The Home high-speed Internet customers, but company officials suggest it eventually will be more widely offered.
