The True Power of IoT in Hospitality: Saying Goodbye to Outdated Systems, and Hello to a Connected Environment

The long waits at check-in desks, manual environment control, physical keys to enter rooms, and the one-size-fits-all services for clients. This is how the hospitality industry looked decades ago.

Whereas today, it’s a totally different story. Technologies have made it possible to use self-check-in kiosks or mobile apps to cut waiting time at reception. Similarly, keyless entry is constantly becoming a standard feature in hotels. Room control has evolved, too. Guests can simply adjust conditions due to voice assistance or through apps.

Eventually, maintenance and issue detection, like elevator faults, smoke or fire monitoring, and temperature irregularities, have become smarter, specifically thanks to sensors that detect malfunctions early on and minimize downtime. Moreover, it’s even possible to forecast potential failures and prevent them from happening.

And perhaps one of the groundbreaking changes in hospitality is personalization. It becomes possible thanks to advanced technologies that collect data about guest habits, such as food choices, spa bookings, or preferred room settings, to offer customized recommendations and services. The technology behind such a paradigm shift in this sector is the Internet of Things.

So, not surprisingly, more and more companies are starting to integrate IoT in their travel and hospitality solutions. Overall, the global market of IoT in the hospitality industry is expected to reach $7.72 billion biy 2035, with an annual CAGR of 9.27% between 2026 and 2035.

And the growing interest in this innovation is for a good reason. Instead of making it sound like just an idea thrown around, let’s dive in and discuss how exactly IoT can make your services incredibly smart and engaging.

Must-Have or Should-Have Tech? The True Role of IoT in Hospitality

In the 21st century, almost everything has become smart. The tourism and hospitality sector isn’t left behind either. Generally speaking, businesses in this sector are now actively creating smart and connected environments to enhance both guests’ experience and business operations.

Take modern smart hotels, for example. Guests here can enjoy contactless action by simply using voice assistants. Moreover, technological advances have made it possible to automatically adjust the room environment for better comfort and energy management.

Driving forces behind these incredible changes are technologies such as artificial intelligence and machine learning. AI specifically comes into play to automate many services and power virtual assistants. ML algorithms, on the other hand, analyze data to streamline decision-making and boost personalization.

But to get there, both AI and ML tools need data, typically in real time, from the physical environment. And this is where IoT sensors come to the rescue. Specifically, they transfer variables to cloud systems and ensure continuous communication between connected devices. This perhaps is a compelling argument to state that IoT is a must-have tech for the modern hospitality industry.

From Smart Rooms to Security Control: Top IoT Use Cases in Hospitality

Given that IoT has become an integral part of hospitality, there are many examples of this cutting-edge technology in the sector. However, we decided to zoom in on the key areas where IoT delivers the most value for this niche.

1. Smart Rooms

The first and perhaps the most important change that IoT brings to the hospitality industry is smart rooms. One of the vivid functionalities of such an environment is keyless entry. Instead of waiting at the front desk to get the key, guests can enter their rooms using digital keys, which are also more secure and less likely to be lost.

On top of that, modern hotel rooms are now equipped with sensors like thermostats, lighting, and motion detection, which significantly elevate visitors’ safety and comfort.

In addition, many hospitality businesses start actively employing a voice assistant in rooms to streamline guest interaction. So, instead of getting out of bed to reach the remote, turn on the TV, or take the phone to contact the administration, visitors can simply delegate these tasks to VAs and enjoy their rest. Let’s admit, this feature creates a literally new guest experience.

2. Predictive Maintenance

Modern hospitality businesses, whether hotels, spas, resort centers, restaurants, and the like, are increasingly deploying IoT devices throughout their facilities. That is precisely because IoT sensors can promptly detect issues such as weather and gas leakage, equipment failures, and energy overuse, and send real-time alerts to ensure timely intervention.

Obviously, if these kinds of crucial data slip away unnoticed, it can lead to serious consequences, heavy fines, and costly downtimes. At the end of the day, in such an environment, when a lift suddenly falls or a gas leakage causes an accident, guests won’t feel safe. And this will deal a blow to the business’s reputation.

3. Security Control

Another prominent use of IoT in hospitality is the creation of a secure environment in the entire hotel area.  Typically, hotels and individuals who rent out their facilities tend to have 24/7 video surveillance. However, they cannot place cameras in the rooms to compromise guest privacy, which makes the detection of unauthorized access more difficult.

Fortunately, IoT sensors serve as a helping hand to this end as well. Motion sensors and smart locks, for example, are being used to detect suspicious activities, while smoke and gas detectors may promptly spot any leakages. This significantly streamlines the safety of the facility without compromising guest privacy.

4. Energy Management

IoT devices today are increasingly deployed in the energy sector to enhance sustainability. Hence, it plays a crucial role in supporting green hospitality.

Let’s say guests forget to turn off the lights or the cooling system when they go out. IoT devices can simply detect this and adjust the lighting and temperature in the room.

This happens thanks to sensors’ ability to identify motion, occupancy, or recognize daylight conditions, allowing them to automatically manage the room environment and save on energy consumption. The same principle applies throughout the entire facility. Sure thing, it not only contributes to sustainability efforts but also helps reduce operational costs.

Mastering IoT Challenges in Hospitality with the Right Solutions

Along with a lot of good that can come from the Internet of Things implementation, there are also some common pitfalls you will need to navigate. Yet, delivering a truly strong and competitive IoT solution for hotels or other tourism businesses is by no means an easy task.

But one thing is for sure: when it comes to possible issues and the best ways to overcome them, all businesses in this sector are in the same boat. Given our solid experience in developing IoT-powered apps, we are sharing the core challenges you may encounter along the way, with the best possible solutions.

Solution 

The best solution here is to employ privacy-friendly sensors like motion detectors, smart thermostats, or RFID-based access systems. You see, such an approach is no longer an option for businesses in this niche. It’s becoming a must-have rule to follow.

Take Airbnb, for example, since 2024, it has restricted the use of indoor cameras. Instead, it encourages using privacy-safe noise monitoring devices, smoke detectors, occupancy sensors, and similar equipment to spot any possible security risks without compromising guest privacy.

Solution

Here, network segmentation can be an optimal solution. Specifically, it will create a shield between compromised and uncompromised data. Simply put, if you keep your devices on a separate network, the hack of one won’t compromise your entire system.

In addition, keep your infrastructure up to date and employ advanced tech to double down on your system’s security. For example, you may utilize blockchain technologies to effectively identify data tampering and shut down compromised devices in a network.

Solution 

When it comes to IoT data transfer, without a shadow of a doubt, you should have several options rather than solely relying on a direct internet connection. For example, consider collecting data through intermediary systems, such as mobile apps.

In this case, a guest’s smartphone serves as a bridge between the device and the cloud. So when the user interacts with the device through the app, the phone uses its cellular connection to transfer data to the cloud.

Another good move is employing a store-and-forward at the edge approach. This data management model ensures uninterrupted information collection and safely stores it even in case of internet loss. Once the connection is restored, the data is automatically transferred to the cloud.

Solution 

Well, we would love to assure you that there are ways to overcome legacy system integration issues, but based on our experience providing digital transformation to different industries, we can insist that legacy app modernization is the only sure-shot way to succeed.

Specifically because modern systems support open APIs, allowing smooth communication between devices and cloud platforms. Thus, making your entire ecosystem more reliable and scalable.

Solution 

To avoid ending up with a mind-blowing TCO, choose IoT devices with durability in mind. Specifically, ensure they are simple to maintain and have self-diagnostics, which can help constantly monitor their performance and reduce downtimes.

Ideally, the device you plan to utilize should come with clear upgrade and replacement plans. That way, in case of failure, you won’t find yourself in a hopeless situation.

Build vs. Buy: Factors to Weigh Before Choosing Between Custom and Ready-Made Platforms

Moving forward with the topic of IoT in the hospitality industry, let’s now take some time to discuss what kind of solution may be the better choice: custom or off-the-shelf.

Frankly speaking, everything is not that simple with this topic. You see, there are different types of IoT devices that hospitality businesses employ, from general ones to more specific solutions designed for particular operational needs.

For example, if you aim to elevate guestroom management and need sensors like thermostats to control lighting and temperature, then a ready-made product may save the day. But if you require a more robust solution with advanced features like environmental control, AI-based recommendations, and complex security measures, then a custom product is what you need.

Also, measure critical factors like long-term revenue and scalability. The thing is, off-the-shelf products can be perfect initially, but often they fall short in meeting your business’s growing needs. Even if they evolve to cover some specific requirements you have at the moment, their expenses will mostly increase. Eventually, they may cost you an arm and a leg.

Meanwhile, bespoke solutions are designed with scalability in mind. In contrast, they require a significant initial investment, but they prove to be cost-effective in the long run.

Fact or Fantasy: How IoT Will Redefine Hospitality in the Upcoming Years

So far, we have pointed out just the core opportunities IoT opens up for hospitality. And perhaps these are already enough to understand that this technology has become a leading tool for modern hospitality businesses aiming to gain a competitive edge.

Now you may be wondering what to expect from this innovation in the future. So, before wrapping up, let’s have a glimpse into what lies ahead for IoT in hospitality.

• Saying goodbye to ‘no-IoT’: Probably one of the core reasons why many small businesses or individuals who rent out their facilities do not employ IoT is the cost. Yet, today, factors such as mass production, cheaper components like sensors and chips, are making this innovation more affordable. As a result, many ventures will start actively utilizing them. This means more automation, greater efficiency, and better services for guests.
• Embracing more non-intrusive sensors: Aiming to double down on guest privacy, more and more hospitality businesses will actively replace video surveillance in some private areas with non-intrusive sensors such as motion, vibration, and sound-level. Given this demand, probably there won’t be a lack of privacy-friendly sensors on the market soon.
• Relying on staffless hotels: This may sound a bit fantastic, but given the technological shift the hospitality industry is experiencing, things are heading in that direction. The industry is likely to face significant automation, and as a result, within the next decade, we may see hotels operating with little or no staff. Robots, for example, can manage room deliveries and cleaning services. However, they will need IoT data to know when and where these services are required. So, robots and IoT are going to work hand in hand.
