Building management system

A building management system, or BMS, controls a building's heating, cooling, lighting, and security from one place. Large offices and shopping centres use them to set schedules and spot faults. Most small businesses rent space inside a building that already has one, run by the landlord. If you run your own space, like a studio or a small venue, smaller smart devices do a similar job. Smart thermostats, timers, and app-controlled lights can follow your opening hours, so nothing runs all night. The main limit is that cheap smart devices don't always talk to each other. Pick a few that work well together rather than one of everything.
