Actually, read that too much editing makes galaxy photos look FAKE.

In studio apartments, those wireless sensors run on batteries that need changing every six months. If tenants forget, the whole phone alert system goes dead. Phone control is cleaner, but it's not maintenance-free. I've seen setups where the control panel gets tucked inside a kitchen cabinet, so it's out of sight. You still need a central hub for most systems to communicate with the phone. Skipping hardware entirely can leave gaps in coverage.
