Bose simply pulled the plug. Speakers costing over €1,000 became expensive paperweights overnight because the manufacturer shut down the cloud. What this has to do with cloud vs. local – and how to decide what belongs in your smart home.
Bose simply pulled the plug. Overnight, SoundTouch speakers that cost well over €1,000 turned into expensive paperweights – because the manufacturer shut down its cloud service. Vorwerk did the same thing with Neato robot vacuums. The list keeps growing.
This is the fundamental problem with cloud integrations in a smart home: you buy a device, but you don’t really own the functionality behind it. That belongs to the manufacturer – and they can take it back at any time. Here I’ll look at what that means in practice, and when cloud integrations still make sense.
ATTENTION: For a limited time until mid-January 2025, you and I will receive not just €50 but €100 at Tibber as a bonus! Just scroll to the end of this article to find out whether a dynamic electricity tariff might be for you.

What are cloud and local integrations?
Cloud integrations connect your devices to external servers over the internet. This lets you access them from anywhere in the world. Examples include Google Nest, Amazon Alexa, and Ring cameras. The cloud offers convenience, but it also comes with risks.
Local integrations, by contrast, run directly in your home network – with no internet connection required. Typical examples are Zigbee devices or ESPHome sensors controlled via a local hub. Local integrations give you more control and independence.
Risks of cloud integrations
Privacy and data security
Many cloud devices send sensitive data to manufacturer servers. A prominent example is the VW data leak in 2024, where a vulnerability exposed the data of 800,000 customers. Security gaps like this can give unauthorized third parties access to your private data.
Vendor dependency
Another risk is dependence on the manufacturer’s services. A well-known example is the Revolv Smart Home Hub, whose servers were shut down by Google in 2016. Users were suddenly left with useless hardware.
Attack surface for hackers
Insecure cloud connections can serve as an entry point into your home network. Once an attacker gains access to a cloud-connected device, they could potentially compromise other devices on your network.
Dependence on internet connectivity
Cloud devices rely on a stable internet connection. If a server goes down or your internet is disrupted, they often stop working entirely. This can cause serious problems with security-critical applications like smart door locks.
Advantages of local integrations
Full data control
With local integrations, all data stays within your home network. You’re not relying on a third party’s data security practices and you minimize the risk of data leaks.
Independence from external services
Local integrations work even without an internet connection. A Zigbee light switch, for example, keeps working even if your internet goes down.
Smaller attack surface
Because there’s no connection to the internet, there are fewer ways for attackers to compromise your network.
Fast response times
Local systems react instantly, since no data has to travel over the internet. This is a decisive advantage for automations and scenarios that depend on precise timing.
How to make cloud integrations more secure
If you want or need to use cloud integrations, there are steps you can take to minimize the risk:
Two-factor authentication (2FA): Enable 2FA to make unauthorized access to your accounts harder.
Strong passwords: Use complex, unique passwords for every service.
Regular updates: Keep all devices and apps up to date to close security vulnerabilities.
Use a separate network: Place cloud devices on a guest network to protect your main network.
When should you choose cloud or local?
Cloud integrations are a good fit if you want to access your devices from anywhere or need complex additional features that depend on external services.
Local integrations are the better choice if you prioritize privacy, security, and reliability.
Conclusion
The choice between cloud and local integrations depends heavily on your individual needs. Both approaches have their pros and cons, but with the right security measures you can minimize the risks. My recommendation: use local integrations wherever possible, and secure your cloud devices carefully. That makes your smart home not just smarter – but also more secure.
Do you already have a dynamic electricity tariff? Tibber is one of the first providers to offer such a tariff in Germany. I’ve been a customer since October 2022, and it’s been a thoroughly positive experience. Tibber offers a clearly structured, modern app where you always have full oversight of your electricity tariff and costs. Pricing is very transparent: Tibber only charges what electricity actually costs on the exchange at any given moment (plus standard grid fees, etc.), plus a service fee of just €3.99 per month.
If Tibber sounds like an option for you, I’d be glad if you sign up via my referral link. That gets both you and me €100 for the Tibber Store, where you can buy various IoT hardware for your smart home. If you’re already a Tibber customer and haven’t used a referral link, you can still do so within 14 days — use code vkccaupl.
Have questions or still unsure? Don’t hesitate to reach out. I’m happy to help you figure out whether Tibber is the right choice for you. And if it turns out it isn’t — you can cancel Tibber month by month at any time!
