Key Takeaways

1. The iGuardStove shuts off a gas or electric stove if left unattended for five minutes.
2. The device uses radar to detect people in the kitchen, instead of motion sensors that are less accurate.
3. It’s meant for seniors and their caregivers, and can notify caregivers if a person doesn’t show up in the kitchen at their usual time.
4. The device is $399 and will ship later in 2026.

Radar-based sensors seem to be having a moment at CES, especially in tech meant for people to keep tabs on their aging family members. One product in particular caught my eye because it’s focused on a single important function—preventing kitchen fires caused by a person wandering away from the stove.

iGuardStove is essentially a smart shutoff for a stove or cooktop. Its new, radar-equipped version costs $399 and can work on gas or electric stoves. (For gas, you’ll need to have a plumber install a shutoff valve.) If you leave the kitchen while cooking, a five-minute timer starts. If you don’t return by the time it goes off, the device either cuts the power to your electric stove, or shuts off the supply line to your gas stove. It can also notify a caregiver that a shutoff event occurred.

Why this is aging-in-place tech

A big theme in smart tech this year is aging-in-place. Most older adults would prefer to live at home as long as they can, but health challenges can make that difficult. When it comes to cooking or other activities that require a sharp mind, mental health issues like dementia come into play, as do medications that can have cognitive side effects. With all that in mind, caregivers often worry about a parent leaving the kitchen while cooking, forgetting that the stove is on.

The National Fire Protection Association reports that cooking fires are the top cause of home fires, the top cause of fire-related injuries, and the number three cause of fire-related deaths. Unattended cooking equipment causes half of those deaths. Older adults are overrepresented as fire casualties compared to younger and middle-aged people.

The device has a five-minute timer, specifically, because that was a safety margin the company developed with safety organization UL, chief marketing officer Jon Landers told me. You can also override the five-minute timer if you’re roasting a turkey or preparing a slow-simmered sauce. In this case you tell the device how long the food is expected to cook, and it lets this cook time complete before resetting to the usual five-minute timer behavior.

Why radar is involved

A previous version of the iGuardStove used motion detectors, but if you’ve ever worked in an office that had lights on motion sensors, you know why that wasn’t a great solution: sit still at a table for too long, and the lights go off. The older version of the device could potentially shut off while you’re just waiting for your dinner to cook, and could be triggered by motion from pets. Radar solves those problems, since it can more accurately identify when a person is in the room.

I’ve been seeing radar in a number of aging-in-place products at CES this year. The Silver Shield from PontoSense uses radar to monitor a person’s presence and movement in a room, reporting movement and potential falls to a caregiver’s app. Luna, a conversation and reminder device from Cairns Health, includes radar that can monitor heart rate and breathing (even through blankets!) when positioned near a person’s bed. The iGuardStove has some monitoring features in common with those devices, but it stays focused on its main task of ensuring stoves aren’t left running unattended.

Radar can “see” a lot, but it doesn’t feel quite as privacy-invading as a camera. Having a device in the kitchen is also a bit less intrusive than in a bedroom, for those who would feel creeped out knowing that a tech device is watching them sleep.

What do you think so far?

Besides shutting off the stove, the iGuardStove can report to a caregiver (via an app, of course) things like what time each day a person first enters the kitchen. It can catch nighttime wandering if the person visits the kitchen at night; it can also send an alert if the person doesn’t seem to be up and active at their usual time. For example, if your mom usually makes coffee around 9:00 every morning, you can ask the app to notify you if the kitchen is still empty at 10:00.

Other monitoring and safety features

Besides shutting off the stove and reporting on the presence of a person in the kitchen, the iGuardStove has a few other clever features. The version of the device made for gas stoves can detect unburned gas, in case somebody left it on without a burner running.

The device can also be configured to keep the stove from being turned on by pets or children, or it can be locked to not allow cooking during certain hours or days (say, at night). The app can also alert a caregiver if temperatures get too hot or cold, prompting them to check in if a heat wave or a cold snap is bad enough to affect indoor temperatures.

While a lot of products I’ve seen at CES are speculative or hopeful in their use cases—I often find myself asking “who would actually use this?”—the iGuardStove seems thoughtfully designed and has a concrete use case and benefit. I was impressed! The new device is expected to ship later this year.
