Hurricane Season Smart Home Checklist for Miami Homes

What a smart home can and can't do in a hurricane

Let's be clear about the limits first. No app keeps water out or holds a window together. Shutters, a plan and good insurance do that. What a well-set-up smart home does is give you information and a few remote controls when you're stuck across town, across the country or at a shelter:

• Is the power on, and if not, since when?
• Is there water on the floor of the laundry room, under the water heater or by the sliding doors?
• How hot and humid is it inside, and is the refrigerator still cold?
• Are the doors locked and the garage closed?
• Can I shut off the main water line from my phone?

Those answers matter most in the days after a storm, when you may not be able to get back to the house and mold, spoiled food and slow leaks do their damage quietly.

Before June 1: the setup checklist

The National Weather Service's advice is simple: the best time to prepare is before the season begins on June 1. For the smart home side, that means:

Power the brains of the house

• Battery backup (UPS) for the modem, router, smart home hub and the AI computer if you have one. A small UPS can keep those running for hours, long enough to send alerts and ride out short outages.
• A second way online. When the power and cable internet go down together, a cellular backup router keeps alerts flowing. Without it, your house can still act locally, but it can't tell you.
• Power monitoring. A simple sensor on a circuit or a UPS reporting status tells you the moment utility power drops and when it returns.

Watch the water

• Leak sensors by the water heater, washing machine, dishwasher, under sinks, near the AC air handler and at doors that take wind-driven rain.
• A smart water shutoff valve on the main line, set to close automatically if a sensor detects a leak. This is plumbing work and should be installed by a plumber.
• Humidity sensors. After a storm, a house without air conditioning can climb quickly into mold territory. An alert above a humidity level you choose is an early warning.

Watch the temperature

• Refrigerator and freezer sensors. Ready.gov says a refrigerator keeps food safe for about four hours without power and a full freezer about 48 hours, and that food above 40°F for two hours or more should be thrown out. A sensor tells you exactly how long things stayed cold.
• Indoor temperature in a few rooms, so you know when the AC comes back.

Secure and see

• Smart locks and garage sensors, so you can confirm the house is locked after you leave in a hurry, and let in a trusted neighbor or contractor with a temporary code.
• A camera or two covering entries and the most flood-prone area, ideally recording locally so footage survives an internet outage.

Write it down

Keep a one-page sheet with your Wi-Fi details, where the water shutoff is, how to reset the hub, and who to call. Put a copy in your emergency kit. A smart home that only one person understands isn't much help in an emergency.

When a storm is forecast: a 72-hour plan

A "storm mode" automation is worth setting up in calm weather. With one tap, or one text, it can pre-cool the house, raise sensor sensitivity, turn off irrigation, close motorized shades where they're safe to close, and send a status report every few hours.

Generators: monitor them, don't improvise

A permanently installed standby generator with a transfer switch is the cleanest way to keep a house running, and a smart home can report when it starts, how long it runs and whether it faults. Installing one is a job for a licensed electrician and, often, a permit.

Portable generators are a different story. Ready.gov is blunt: generators and fuel should always be used outdoors and at least 20 feet from windows, doors and attached garages, because carbon monoxide can kill. Install working carbon monoxide detectors on every level of the house. No smart home feature changes those rules.

When power returns, surges can damage electronics. Ready.gov recommends disconnecting appliances and electronics during an outage. A UPS with surge protection on your network gear adds a layer of protection.

If you're away for the season

Hurricane season starts June 1, right around when many seasonal residents head north. That's the most common reason Miami owners want remote monitoring: the house sits empty through the riskiest months.

A good "away" setup for a seasonal home includes:

• Daily or weekly status texts, so silence means something is wrong.
• Alerts that go to two people: you and someone local who can get there.
• Temporary lock codes for a property manager or neighbor, with an activity log so you can see when they came and went.
• Humidity and temperature alerts tuned for a closed-up house.
• An automatic water shutoff, so a burst supply line doesn't run for weeks.

We cover this in more depth in our guide to freeze, leak and power alerts for second homes, and in our second-home monitoring service.

Condos and buildings

If you live in a condo tower on Miami Beach or Brickell, your building controls a lot: shutters or impact glass, generators for common areas, water risers and when elevators run. Check your association's rules before installing a water shutoff valve or anything that touches building systems. Inside the unit, leak sensors, temperature and humidity monitoring, a smart lock (if the building allows it) and battery backup for your network are usually straightforward.

Insurance and flood coverage

Two things to check now, not when a storm is on the map:

• Flood insurance takes time. According to FloodSmart, the National Flood Insurance Program's site, coverage generally takes effect 30 days after purchase, with a few exceptions.
• Ask about device discounts. Some insurers reward water leak detection or monitored systems. Policies differ, so check with your insurer before buying anything for that reason.

A sensible starter kit

How Kotoh Home handles this

We set this up as part of our smart home installation for homes in Miami Beach, Coral Gables and Coconut Grove and Key Biscayne, starting with a solid, backed-up network. With a private AI assistant, you can text the house "storm mode on" or "how's the house?" and get a plain-English answer about power, water, temperature and doors. Because the AI runs on a computer in the house, those details aren't sent to a cloud AI service.

Whatever system you use, follow official guidance first: Miami-Dade County's hurricane preparedness resources, the National Hurricane Center and evacuation orders always come before anything on your phone.
