Direct answer
Control4 is professionally installed, so initial configuration and many system-level changes are handled by an authorized integrator. Homeowners can still use the app, remotes, touchscreens, scenes, and permitted personalization tools; professional installation does not mean calling a dealer for every daily adjustment.
According to Control4's current services page, core systems can operate locally without a subscription. Control4 Connect adds or supports features such as remote access, supported voice and Apple integrations, notifications, backups, updates, and expanded personalization. Requirements vary by system age, controller, software, and desired feature. Before approving a proposal, ask which functions work locally, which require Connect, what the current subscription includes, which changes the owner can make, and what remote or onsite support costs. Recheck current terms at publication because subscription packaging can change.
