Smart Kitchen Systems Compared: Home Connect, SmartThings, LG ThinQ, Miele@home and Open Platforms

Smart Kitchen Systems Compared: Which Platform Really Makes the Connected Kitchen Better

The smart kitchen has long been more than an oven with an app. In practice, it's about remote control, automations, energy efficiency, status notifications and integration into a larger smart home system. In my view, however, the market is often presented as unnecessarily complicated. In reality, a handful of platforms are emerging that are relevant for everyday use: Home Connect from BSH, Samsung SmartThings, LG ThinQ, Miele@home, and open solutions such as Home Assistant or KNX.

Anyone planning a new kitchen or looking to gradually connect existing appliances should not be guided solely by the look of the devices. What matters more is how well apps, brands and automations work together. This is precisely where the differences between closed manufacturer ecosystems and open platforms become most apparent.

What Smart Kitchen Systems Offer Today

Modern smart kitchen systems connect appliances, apps and sometimes voice assistants or sensors into a shared operating concept. Typical devices include ovens, hobs, extractor hoods, dishwashers, refrigerators and occasionally fully automatic coffee machines or washing appliances, all integrated under the same account. In everyday cooking, many functions initially seem of little benefit, but over weeks they deliver a noticeable improvement in convenience.

I find status queries and notifications particularly useful. Instead of checking in the kitchen whether the dishwasher programme has finished, a quick glance at your smartphone is enough. An oven can link recipes with matching programmes, an extractor hood responds automatically to the hob, and a refrigerator alerts you to open doors or temperature issues. This doesn't save hours, but it reduces friction in daily life. And honestly – who hasn't sat in the car on the way to a holiday and wondered whether the stove was really turned off?

There are also efficiency benefits. Some systems help with time-shifted operation, energy monitoring or optimised use of programmes. This becomes particularly relevant in households with photovoltaic systems, variable electricity tariffs or more complex home automation. At the same time, one should remain realistic: not every app function is equivalent to genuine automation. Much of it remains assistance, not autonomy.

Home Connect in Profile

In my view, Home Connect is currently the most defining smart kitchen system in the European built-in appliance market. Behind it stands the BSH Group with Bosch, Siemens, Neff and Gaggenau. Accordingly, the number of compatible devices in new-build and renovation kitchens is large. Anyone operating within the Bosch-Siemens environment will typically find the most cohesive and practical everyday solution here. Unfortunately, multimedia devices such as televisions are absent from the range. Providers like LG and Samsung are more broadly positioned in this regard.

The app covers typical kitchen functions very comprehensively: programme start and monitoring, push notifications, recipe integration, remote diagnostics for selected devices, and the linking of multiple products within a household. In everyday use, this usually works in a pleasantly clear manner. Remote control is particularly well-developed for ovens and dishwashers without feeling overloaded. The automatic pairing of hob and extractor hood is also one of those features you quickly can't imagine doing without.

The real strength, however, lies in the broader ecosystem. Home Connect is not just an app, but a platform with interfaces. This allows the system to be integrated into voice assistants and external smart home solutions, among other things. For many users, the journey begins through brands like Siemens, for example with a [url="https://www.siemens-home.bsh-group.com/de/produkte/kochen-backen/backoefen-herde/iq700-backoefen/studioline",name="Smart Home kitchen appliances from Siemens Studioline",title="This page leads to the smart Siemens Studioline ovens"] or through Bosch Smart Home. The latter, however, is not identical to Home Connect, but rather a complementary smart home system for sensors, heating and security.

In the broader market, My AEG Kitchen App, HomeWhiz, hOn App and ConnectLife also play a role. These apps are relevant when using appliances from AEG, Beko/Grundig, Haier/Candy/Hoover or Hisense. In a direct kitchen comparison, however, Home Connect usually remains the reference solution when it comes to built-in appliances and broad brand coverage within a single group.

SmartThings and LG ThinQ Compared

Samsung SmartThings and LG ThinQ take a different approach from classic kitchen platforms. Both systems come from large electronics corporations and think about the home more holistically. This directly affects the kitchen: the app is not just for the oven, but also for the TV, air conditioning unit, washing machine, robot vacuum, energy overview or sensors.

SmartThings is clearly the more open and platform-oriented solution. Anyone who already uses Samsung devices or is looking for a connection between home automation and household electronics will benefit from this. I see the greatest advantage here in the broad ecosystem concept. Kitchen appliances become part of a larger set of rules, for example in combination with presence detection, energy scenes or routines. This feels more modern than a pure device app, but also requires a somewhat deeper engagement with the system.

LG ThinQ, by comparison, is more closely tailored to its own devices. The app often feels somewhat more straightforward, and in some cases more accessible, when exclusively LG products are used. In the kitchen, the benefit is solid, but the device portfolio in the European built-in kitchen market is not as broad as that of BSH or Miele. ThinQ is therefore primarily of interest to households that have already consciously opted for LG and want a unified app for multiple device categories.

The key difference lies less in individual app menus than in strategic direction. SmartThings wants to be the control centre, while ThinQ is more of an operating layer for LG hardware. Those seeking flexibility often look to SmartThings first. Those who want to stay as seamlessly as possible within the LG ecosystem are usually better served by ThinQ.

Miele@home and Premium Features for the Kitchen

Miele@home is clearly aimed at users who buy high-quality built-in appliances not only for their material quality and longevity, but who also expect digital convenience. In practice, the system feels less playful than some competitors, but is usually very cleanly focused on core functions. This fits well with Miele's positioning.

The connectivity covers typical kitchen appliances such as ovens, steam cookers, fully automatic coffee machines, dishwashers, refrigeration units and extractor hoods. I particularly appreciate the remote monitoring, targeted notifications and the well-coordinated communication between devices. Premium features here are not created by as many gadgets as possible, but by the quality of execution. When a device reliably reports programmes, can be sensibly started remotely, or works together with recipe and assistant functions, that is often worth more in everyday life than a long list of experimental options.

The added value is most evident in demanding households with high-quality kitchens, clear operating requirements and high frequency of use. Miele@home is less a tinkerer’s system than a controlled, elegant comfort platform. The price of the devices remains the biggest barrier to entry, however, and those who want to automate with maximum openness will encounter limitations.

From my experience, a simple principle applies in the smart kitchen: the higher quality and longer-lasting the appliances are planned to be, the more important a stable software and update strategy becomes.

Open Platforms and Cross-Manufacturer Solutions

Open platforms such as Home Assistant or KNX become interesting whenever multiple brands come together in a kitchen, or when kitchen technology is to become part of a comprehensive building automation concept. This is precisely where manufacturer apps naturally reach their limits. They control their own devices well, but the logic across multiple systems often remains limited.

Home Assistant is for technically minded users currently the most dynamic solution. Through integrations, Home Connect, parts of SmartThings and other components can be incorporated into shared automations. For example, ventilation can respond when cooking takes place, lighting moods can be linked to device status, and energy flows from PV systems or battery storage can be included in rules. The potential is enormous, but it requires time, familiarisation and a willingness to handle maintenance yourself.

KNX takes a different path. In new builds or high-quality renovations, KNX offers a very stable and professional foundation for lighting, shading, ventilation, switches and sensors. Kitchen appliances can be integrated in a complementary manner, usually without the same app depth as in native manufacturer solutions. In return, you get a durable, cross-manufacturer automation structure. Voice assistants and Matter can serve as bridges, but do not resolve every compatibility issue.

The limitation of open solutions lies primarily in support. If an integration fails after an API change, no kitchen studio can help. Those seeking maximum reliability are often better off staying closer to the manufacturer. Those wanting maximum freedom will sooner or later end up with open hubs.

Important Comparison Criteria Before Buying

Before buying, I would clarify three questions:

1. How good is the app in everyday use,

2. how open is the system, and

3. how reliable are updates and data protection processes?

Especially for appliances that will be used for ten years or more, software quality is not a secondary consideration. A nice app interface is of little use if features are barely developed further after two years.

Equally important is the existing smart home technology. Anyone already using Bosch Smart Home, Samsung components, voice assistants or a Home Assistant hub should check which platform fits best. Setup also differs considerably. A pure Home Connect setup is usually ready to go more quickly than an open, cross-brand solution.

Costs play a role on two levels: the device price and later expansion. Closed systems are often simpler, open systems more flexible in the long term. It is therefore worth taking a sober look at your own usage rather than feature lists. Anyone who only wants status notifications and remote start does not need a complex automation system. Those who want to connect energy, presence, lighting and kitchen appliances should plan more openly.

Which Solution Suits Which Household

For beginners with a new fitted kitchen and a clear brand preference, Home Connect is in my view currently the most obvious recommendation. The system is mature, widely represented in the market and particularly relevant for everyday kitchen use. Anyone who has already decided on Bosch, Siemens, Neff or Gaggenau will get the most rounded overall experience here.

SmartThings suits households best that do not view the kitchen in isolation, but as part of a larger smart home. LG ThinQ makes sense for users with a strong commitment to LG, while Miele@home is most convincing in the premium segment when build quality and controlled convenience are the priority. Open solutions like Home Assistant or KNX, on the other hand, I would only explicitly recommend when the desire for individual automation is genuinely strong and technical interest is present.

My conclusion is therefore a pragmatic one: brand loyalty usually rewards closed systems, while mixed device setups benefit from open platforms. Anyone planning today should not just look for the best individual device, but for the system that will still make sense for their household in five years. Compare apps, integrations and support just as carefully as design and features. Discover manufacturer details directly from the providers, for example via [url="https://www.home-connect.com/de/de/",name="Home Connect",title="This page leads to the official Home Connect platform"], [url="https://www.smartthings.com/de",name="Samsung SmartThings",title="This page leads to the official SmartThings platform"], [url="https://www.lg.com/de/lg-thinq",name="LG ThinQ",title="This page leads to LG ThinQ"], [url="https://www.miele.de/domestic/miele-at-home-2155.htm",name="Miele@home",title="This page leads to Miele@home"] and [url="https://www.home-assistant.io/",name="Home Assistant",title="This page leads to the open platform Home Assistant"]. Those who build on this and think about their own kitchen systematically will ultimately make the better purchasing decision.

If you are currently planning a new kitchen, now is the time to specifically check your preferred brands, the desired smart home connectivity and the effort required for setup and expansion. This is how digital accessories become a system that genuinely delivers in everyday life.
