Kitchen fires are a common household danger, especially for older adults living alone. A new device called iGuard, featured at the 2026 Consumer Electronics Show, is designed to help prevent them.

If someone starts cooking and leaves the kitchen, iGuard begins a five-minute timer. If no one returns, the device shuts off the stove or gas line automatically.

Unlike many shutoff devices that rely on motion sensors, iGuard uses radar technology to more accurately detect when someone has left the kitchen.

Caregivers can also receive alerts on their phones and even shut off the stove remotely. The device can also detect unburned gas and turn off the gas supply before it becomes dangerous.

Devices like iGuard are part of a growing group of smart home safety technologies designed to help people live safely and independently while giving family members peace of mind.

iGuard is designed for electric plug-in stoves and is expected to cost between $400 and $500. While it is one of the more advanced stove safety devices available, simpler monitoring devices with fewer features can cost as little as $40.
