The smart kitchen: Which connected devices are really worth it

The digitization and networking of household appliances, often summarized under the term "Smart Kitchen" or smart kitchen, offer new possibilities in kitchen use. Modern systems can be divided into two core areas that provide different functions:

1. Autonomous sensor systems: These operate largely invisibly in the background to control cooking and baking processes and improve the quality of results.
2. App-based networking: This offers extended control, monitoring, and service functions for, for example, dishwashers for more comfort and flexibility.

This guide analyzes the potential of these developments and highlights both the advantages and important critical aspects for consumers.

1. Autonomous sensor systems for process optimization in the smart kitchen

A significant advancement lies in the integration of sensors that automatically monitor and control cooking processes. These systems aim to reduce human uncertainties in preparation and enable consistent results without requiring interaction with an app.

Moisture sensors in the oven: These sensors continuously measure the moisture content in the cooking chamber. Based on this data, the system detects the progress of the baking process, for example, with a cake. Heating type, temperature, and baking time can be automatically adjusted. The need for manual cooking tests can thus be eliminated.
Multipoint roasting thermometer: Unlike conventional roasting thermometers that measure at only one point, these sensors record the core temperature at several measuring points. This allows a more precise recording of the core temperature, which is especially advantageous for large or irregularly shaped roast pieces to achieve the desired degree of doneness.
Temperature sensors for cooking pots: A sensor attached to the cooking pot continuously measures the temperature inside the pot and communicates with the cooktop. The cooktop then automatically regulates the energy supply to maintain the preset temperature constantly. This is intended to prevent liquids from boiling over.
Integrated roasting sensors in the cooktop: A sensor integrated directly into the cooktop monitors the temperature of the pan. The user selects a temperature level, and the cooktop maintains it constantly. This can be helpful when preparing foods that require precise temperature control, such as steaks or pancakes.
Air quality sensors in range hoods: This sensor measures the density of cooking fumes in the air. Based on this data, the range hood automatically adjusts its power level. Manual control is no longer necessary. After the cooking process is finished, the system can activate a post-run mode and then switch off independently.

2. App-based networking: Comfort and remote control of kitchen appliances

The networking of devices via a central smartphone application enables remote control and offers a range of service functions.

• Remote control and status monitoring: Devices can be activated remotely, for example, preheating the oven. The app also provides real-time information about the device status and sends notifications when a program is finished or in critical conditions such as an open refrigerator door.
• Integrated cameras in cooling devices: Allow the user to view the contents of the refrigerator remotely to simplify shopping planning.
• Intelligent program assistance: For complex devices, assistants in the app can help. Based on information about the type of dishes and degree of soiling, the optimal washing program can be recommended, for example.
• Integrated recipe functions: Recipe databases can directly send the appropriate device settings to the oven, simplifying preparation.
• Remote diagnosis by customer service: In case of a malfunction, the user can allow customer service temporary access to diagnostic data. Problems can often be identified remotely, saving time and costs.

3. Device communication and system integration in the kitchen

Functionality is expanded when devices communicate directly with each other or are integrated into overarching systems. An example is the coupling of cooktop and range hood, which automatically synchronize their performance. Open platforms also enable integration into smart home systems or the creation of individual automation rules via web-based services.

4. What you should consider before buying

Despite the undeniable comfort gains, the potential disadvantages and risks should also be critically weighed before purchasing smart kitchen appliances.

• Costs: Devices with advanced sensors and networking functions are significantly more expensive to purchase than their non-networked counterparts.
• Durability and digital obsolescence: The mechanical lifespan of a household appliance is often 15 years or more. The life cycles of software and apps are significantly shorter. There is a risk that the manufacturer will discontinue support for the app after a few years, no longer provide security updates, or shut down the servers. The smart functions could thus become unusable long before the device is mechanically defective.
• Data protection and privacy: Networked devices continuously collect usage data. Consumers should find out which data is collected (e.g., cooking habits, operating times), where it is stored (manufacturer servers), and for what purpose it is used. Insufficient security can pose a risk to privacy.
• Reliability and repairability: Additional electronics, sensors, and software increase complexity and create more potential sources of error. A stable WLAN connection is a basic requirement for many functions. Repairs to smart electronics can be more complex and costly than with conventional devices.

Conclusion: A conscious decision for or against networking in your kitchen

Modern kitchen technology can simplify everyday life through targeted automation and remote control and improve the quality of cooking results. The greatest benefit often lies in autonomous sensor systems that also work reliably without networking. However, the decision for or against a fully networked kitchen should be made consciously. Consumers should carefully weigh the practical advantages against the higher costs, the unresolved digital durability, and concerns about data protection. An intelligent kitchen is ultimately one that meets individual needs and where the advantages clearly outweigh the potential risks.
