Get a stove reminder without pretending it is a safety system
Starting to cook also starts a reminder, and only a person or an appliance-approved status signal clears it.
Best for: Households that want a persistent cooking reminder tied to a deliberate timer or a manufacturer-supported appliance status.
Not for: Automatic shutoff through a general-purpose smart plug, improvised sensors near burners, or replacing smoke alarms and attentive cooking.
Why this exists
A visible reminder that stays active until someone acknowledges it is more useful than a sensor guess about what is happening on the stove. It remains a reminder, not a claim that the smart home knows whether every burner is safe, because power, temperature, presence, and motion can all be ambiguous.
Use a timer every time cooking starts. If the appliance exposes a supported status through its manufacturer, that status can improve the message, but it still does not replace checking the controls in person.
What I used
| Job | Good enough | Never think about it | Notes |
|---|---|---|---|
| Start a cooking reminder | A physical kitchen timer or deliberate phone timer | A visible household cooking mode started by the cook | Starting the timer must be part of starting the appliance. |
| Read appliance status | No personally verified recommendation yet | Manufacturer-supported status for the exact appliance | Verify what each state means. Do not infer individual burner state from whole-appliance power. |
| Shut off cooking equipment | A person uses the appliance controls | Purpose-built, approved safety equipment installed for the exact appliance | No general-purpose smart plug or improvised relay is recommended. |
Logic
- Trigger: A person deliberately starts Cooking mode or an approved appliance signal reports active cooking.
- Conditions: Record which signal started the reminder. Do not require missing motion or Away mode.
- Action: Start a visible timer and send a persistent reminder when the chosen interval expires.
- Wait / timeout: Use the cook’s intended interval, with an earlier check for unfamiliar cooking.
- Stop condition: A person checks the appliance controls and clears the reminder.
- Manual override: The appliance’s normal controls and a physical timer remain available.
Setup notes
- Put a physical timer or one-tap Cooking control next to the normal cooking workflow.
- Make the reminder name the appliance and ask a person to inspect every control.
- Keep the reminder visible until acknowledged.
- Do not silence it automatically when the house enters Away or Bedtime.
- If using manufacturer-supported status, test preheat, normal cycling, residual heat, self-clean, disconnected, and unavailable states.
- Treat unavailable or ambiguous status as “check the appliance,” not “off.”
- Keep working smoke and carbon-monoxide alarms independent of this reminder.
Advanced features
Add a leaving-home check
When Away mode begins, remind the last person to check the stove if Cooking mode is still active. Do not remotely report that the stove is off unless the exact appliance provides a verified state.
Escalate an unacknowledged reminder
Send one follow-up to another responsible adult if the first reminder remains unacknowledged. Avoid repeated messages that train people to ignore it.
Failure modes
- Nobody starts Cooking mode: Keep a physical timer at the appliance and make it part of the cooking habit.
- The timer is wrong for a long recipe: Let the cook choose or extend the interval explicitly.
- Appliance status is unavailable: Ask for an in-person check and repair the integration.
- Power appears low while a burner is hot: Do not clear the reminder from power alone.
- Motion stops while cooking continues: Do not treat missing motion as abandonment or safety.
- A reminder is acknowledged remotely: Keep the wording focused on checking the physical controls, not merely tapping a notification.
Done when
- Starting a cooking session also starts a visible timer or Cooking mode.
- The reminder names the appliance and remains visible until acknowledged.
- Away and Bedtime do not silently clear an active cooking reminder.
- Missing or ambiguous data asks for an in-person check.
- No general-purpose smart plug, improvised heat sensor, or inferred automatic shutoff is used.
- Smoke and carbon-monoxide alarms operate independently.
FAQ
Can a normal smart plug monitor or shut off a stove or oven?
No general-purpose plug is recommended here. Ranges and ovens may be hard-wired or use high-current circuits, and gas appliances have additional hazards. Use only equipment approved for the exact appliance and installation.
Is no motion in the kitchen proof that cooking was abandoned?
No. Someone may be in another room while food cooks, and a motion sensor can miss a person who is still. Motion can add context but must not decide that a burner is safe.
Can a temperature sensor near a burner detect whether the stove is on?
It is not a dependable safety signal. Placement, steam, sunlight, another burner, and residual heat can all produce misleading readings.
