Even though the functionality of your smart home app directly depends on the device, there are some common features that most smart home apps need.
The sign up stage in smart home apps should be easy, yet secure. During this process, you can offer users to set up all the available authentication features (password, Face/Touch ID, personal security questions, etc.).
Surely, all the settings should later be changeable, but you should make access to them well-protected using any of the security features that we’ve already talked about.
Normally, to change security settings, users need to pass all the previous security layers.
Think about the ways you could help users restore their passwords in case they forget them. It can be as simple as a phone call or a multi-layered system with multiple confirmation steps.

Signing up often means connecting users’ phones to devices. You can make it automatic — so when users turn on the device for the first time, a notification with a “Connect” suggestion pops up. Alternatively, users can do it manually by following the guide on your specific device, but again, it really depends on each use case.
The Home Screen is a place where users have quick access to all the features. We can’t really tell you what to place on this screen since functionality is highly variable depending on the type of your device.

All apps for smart home devices most likely need turn on/off and connect/disconnect buttons. Other features on this screen are mostly specific to your particular use case.
In case your smart home device doesn’t have any features but is used for measurements (for instance, temperature and humidity in the room), you should place the information your device provides here.
By the way, if you connect several devices in one app, the Home Screen should be a place where you display all the devices and allow users to access each one’s functionality, including voice control.
The Device Screen is a part of the app where users can access all information about the appliance. Just like with the Home Screen feature, the data presented on this screen depends on each specific use case, however, there is some general information that you can place on your screen.
This screen is normally accessible from the Home Screen.

That can include:
Basically, the onboarding guide is a step-by-step instruction on how to set up the device, connect it to the app, how it works in general, what features there are, etc. The information there should be well-structured and clear.

Even though the guide should be simple, it’s still a great way to stand out. First things first, you should make sure that it fits the general style of your brand.
In addition, it might be a great idea to create a “spirit animal” for your brand that will guide customers through the setup process; it can be an actual animal like a cat or it can also be something else, for example, a customly designed robot, impersonation of your device, etc. Surely, it’s not essential but will definitely make the process funnier and more pleasant.
You can implement a chatbot feature here as well. When instructions are given, the chatbot can ask if everything is clear. If not, the bot can give a more detailed explanation, offer to take a step back to review the guide once again, or contact a real support specialist.
How to Make a Chatbot Using JS
Generally, try to gamify the process a little so customers enjoy and value your services.
If your app is targeted at centralized control of several devices simultaneously, you can consider implementing this feature. Group features allow users to group devices under a single command.
So, let’s say a user puts a smart lamp, air conditioning, and a speaker in a group; then, they create a “BedTime” button for this group; once they press this button, the smart home app sends different commands to the grouped devices.
For example, the lamp is turned off, the air conditioning is switched to the pre-set regime, and a sleep meditation routine is played on the speaker.
Smart home systems are a part of the IoT industry, which is why you sometimes can use tech stack for other IoT devices (image by Antareza Ghifary)
You can offer group templates for different rooms if you have enough devices for that. If not, just make it highly customizable so customers can fully tailor it to their needs.
Push notifications are an important part of most smart home apps. You can use them for both alerts (like failures of systems, fires, trespassing), as well as regular situations (e.g., “food is ready”).
Smart home systems for IoT devices should have the push-notification feature (image by Antonin Kus)
You should also make sounds customizable so users can mark different actions with different notifications. It’ll let them know if it’s something that requires their immediate attention or not.
When building a smart home app, data flow needs to be taken care of with extra attention. Optimizing it can significantly reduce smart home application development costs and time, boost the user experience, and improve security.
In this section, we'll explore all the components of the data management process that you'll encounter when you decide to build your own smart home app.
The backend of your app is where data is collected; there are several ways of how you can set up this process, and you should remember that it will directly affect the time and costs of the development.
Home automation technology has a lot of data-related interactions between a smart device, mobile applications, and other parts of Internet of Things devices’ systems (image by Cleveroad)
The first thing to pay attention to is frequency and accuracy of measurements. These two factors are interrelated — the more often you measure data, the more accurate the results are.
If you know that a certain level of accuracy is enough, there’s no reason for you to perform measurements more often than needed to reach it. So, determining the sufficient measurement frequency can help you optimize costs on data collection.
Additionally, energy consumption depends on accuracy as well. To minimize costs, you should test how much energy you’ll need to reach the needed accuracy level and set up the process in a way where data collection won’t go beyond it.
You can also think about the duration of data’s relevancy. If you know that the collected data will be irrelevant after 4 hours, you can set the maximum time gap between measurements.
Data processing is the next step, which also requires extra attention. If you’re going to use 3rd-party providers for data processing, make sure to take a good look at their statistics (for example, how often they’re exposed to breaches) and terms of co-working (e. g., how you can change the vendor).

For smart home devices, it’s essential to enable real-time data processing. Smart locks, coffee machines, air-conditioning, etc. — well-functioning of similar devices is based on accurate real-time data processing.
Since internal storages of smart home devices are not that capacious, you’ll most likely need external storage or use additional internal storage. There are two ways of enabling such cloud and offline storages.
So, cloud storages are really easy to set up — you simply subscribe. Usually, it’s a monthly subscription for a certain capacity. Another option is the “pay-as-you-use” model which implies that you pay for as much storage as you use in a certain period of time.

Cloud storage is useful in multiple ways:
However, cloud storages have a higher exposure to data leaks and breaches because of their accessibility over the Internet. Surely, there are ways to enable high-level security (we’ve already talked about that in the FAQs section), so, with great security features, you should be fine.
If you’d like to have physical data storage, you can use SD cards, FTP servers (special servers for data storing and transferring), etc. It’s safer, yet less convenient, more expensive, and uses up more energy.
Data engineering implies analyzing data at different stages of the process, extracting information that you pass to clients, and transforming it from raw data to something that a regular person would understand.
IoT devices for home automation (aka smart home systems) have multiple data analysis steps for maximum utility (image by Patryk Szymański)
Data engineering should also work in real time along with data processing. You can perform analysis several times a day to provide users dynamics and trends (for example, humidity at their house).
Additionally, you can make conclusions and what steps to take next based on the data (for example, turning on the humidifier 3 times a day for 30 minutes to reach a sufficient humidity level).
To provide better user experience, you can offer visualization features to your users. That may include:

It might be reasonable to implement visual data categorization. For example, instead of making multiple graphs for various data periods in several chart types, you can simply allow users to choose how and over what period of time the data should be presented on one screen.
To help you with building a smart home app, there are platforms for the development process — a set of features and tools.
Such platforms can provide a wide range of services for a smart home app developer:

The most reliable smart home and IoT platforms on the market are AWS IoT, IBM Watson, Google Cloud IoT, Salesforce IoT, Kaa. There are really no specific use cases that can show when it is and isn’t reasonable to use a smart home platform.
You and your mobile app development company can manage all of these aspects on your own, which will take more time but be more beneficial in the long run. If you use a platform, you’ll have to pay a fee for a subscription or a use-based one, which can increase in the future.

Creating a smart home app may seem difficult, but don't worry! We have simplified the procedure into seven essential phases that will lead you through the process of growth. Let's dive in and make a smart home app!👇
Your first decision lies in the type of solution you want to offer. Will it be a single-device-focused app or a comprehensive system allowing users to control various devices seamlessly? While the former is quick and cost-effective, the latter promises a richer user experience.
Consider whether to use an existing platform or develop a unique solution from scratch, taking into account the specific needs of your product, including the Internet of Things prototype development phase. Leveraging pre-built platforms can save time and resources, but building your own equipment allows for a more customized experience. Striking a balance, starting with a ready-made platform for an MVP, ensures you validate your product concept before heavy investment.
Craft user scenarios to understand the steps your users, taking into account their specific user roles, will undertake to achieve their goals. This user-centered approach ensures your app aligns with user behavior and demands, creating a seamless and satisfying experience.
Identify and prioritize core features such as registration, onboarding, user profiles, room grouping, customizable scenarios, alerts, notifications, and analytics to make a smart home application. These features lay the foundation for a user-friendly and functional smart home app.
Enlist the devices your app will support. A broad compatibility range gives users more choices, fostering a diverse and inclusive user base. Ensure your technology platform accommodates various sensors and gadgets, allowing users to personalize their smart homes.
Choose between cloud services and local storage for data management. Cloud storage offers accessibility from anywhere, while local storage provides a robust solution. Select based on your app's specific needs and user preferences.
In the era of cyber threats, prioritize security from the outset. Utilize encryption, encourage users to use separate networks, and regularly update and patch your app. Design your architecture with security gates to prevent potential breaches.
If you integrate your smart home device and/or app with similar 3rd-party providers, your customers will be able to control the device through such integrations.
To integrate with them, you simply need to get access to their APIs or SDKs that are always available on the websites:
However, it might be more difficult to tailor such integrations to your use case.
The IoT industry is full of various 3rd-party integrations (image by Patricia Reiners)
For voice commands to function, Google Home uses _actions _and Alexa uses skills. These commands need to be placed on a server — any server for Google Home and the AWS Lambda server for Alexa.
If you intend to develop a smart home app incorporating custom skills and actions, it is necessary to submit them to your provider for approval. However, there are a lot of pre-written commands that you could use. So, make sure to thoroughly look through the list, maybe you’ll find all commands you need there and save time by not having to approve them.

We can’t tell you exactly how much the development of your smart home app will cost since it depends on your specific use case. However, there are certainly a lot of aspects that you can think about in advance as they’ll directly affect your development costs:
Smart home automation development requires careful consideration of these factors to determine the overall cost and feasibility of your project.
Smart home app development is quite a complex process and requires a lot of patience so that everything functions seamlessly, often necessitating the expertise of an IoT application development company. Even though it’s challenging, there shouldn’t be any difficulties with an experienced Tech Partner.
Let’s briefly summarize what we’ve covered in the article:
If you need some help with the development, have any questions left, or simply want to share your thoughts with us, feel free to reach out. We’d be happy to help you!
In this section, we’ve answered a couple of questions that you might have regarding home automation application development.
First, let’s talk about the firmware — a part of the software that enables the communication between smart home appliances’ physical parts (hardware). If it’s already developed and well-functioning, there will be no challenges left to handle while building the app itself.
Even though there will probably be bugs, fixing them won’t be a big deal for an experienced development company.
If you're just beginning the process of developing the firmware, we recommend completing that stage first before proceeding with app development. Working on these two things simultaneously will make it harder to spot and fix bugs, test various versions of the app, and generally deboost the process.
One of the most convenient ways to handle such a situation is buying the device with an already built and tested firmware. This way, you save a lot of time and significantly speed up the process without losing efficiency.

Additionally, you need to update your chosen firmware to fix bugs, enable new functionality or just change something about your smart home app or appliance. To make it quick and easy, we’d recommend implementing Over-the-Air (OTA) updating.
This method allows installing updates remotely and automatically. — It's useful in many cases: if you don’t let your clients use an appliance until it’s updated and don’t make it automatic, it can cause trouble.
Let’s say you offer an app for smart pressure cookers. One of your clients decides to cook something, turns the device on, and leaves the house. Normally, people set timers, however, sometimes, one prefers turning it off manually through an app. If you release an update, that person won’t be able to use the app and is likely to at least overcook the dish if not burn it.
Such situations can significantly discredit you as a reliable provider. There are several ways how you can prevent them:
In conclusion, to ensure a seamless user experience, it is crucial to develop a smart home automation app that seamlessly integrates with well-tested firmware and provides user-friendly update options.
The communication between all parts of a smart home device’s ecosystem is enabled with the help of protocols — a language that machines speak.
So, to choose the right protocol for your use case, there are multiple factors that you should take into account: price, power consumption, connectivity range, bandwidth, what industry it’s most suitable for, etc.
Smart home automation system in the Internet of Things industry has a complex data exchange that includes exchange between a data storage, a smart device, and a mobile app (image by Andika Wiraputra)
In this table, we’ve gathered information about the most widely used protocols for smart home devices:
Wi-Fi is an affordable option, 10- to 100-meter connectivity range, complies with most of the existing smart home devices. But it consumes a lot of energy and its efficiency depends on the distance between device and signal source
When using the Z-Wave protocol, communication is enabled through a radio channel. It can connect 1500 smart objects at one time, however, radio frequencies may be better or worse depending on the location, which makes Z-Wave unstable
Affordable, compatible with many of the existing solutions, yet, the frequency is quite similar to Bluetooth and Wi-Fi — the more devices there are on similar frequencies, the worse the connection is
Bluetooth Low Energy (BLE)
Low energy consumption, various connectivity range options, high-level security, fast data exchange. One of the best options for smart home devices
Affordable yet slow compared to other protocols. Since it enables connection through power wiring there can be interferences
Compatible with most modern technologies, fast, quite expensive. Plus, you don’t need a hub when using Insteon
Low power consumption, standardized with a decent security level, able to self-fix breaches. But it doesn’t support a massive amount of information and supports not many devices (250) at a time, yet, surely enough for a smart home
Universal Powerline Bus (UPB)
Fast, low interference chance since it’s really receptive and not likely to catch signals from other protocols. Due to the same reason it can coexist with other protocols. Yet, it’s quite costly to install since units are expensive ($90/unit), and it also doesn’t support some of the modern devices
If you’d like to offer several smart home devices and want users to be able to control them through a single app, there are several options on how you can enable it.
The first thing you should take into account is that it’s only possible to use one app for several devices when they use the same protocol. So, you can build/buy devices with the same protocol, but it’s not always convenient and reasonable to do so since different protocols suit different use cases better.
Instead, many companies opt for a smart home automation hub — it’s sort of like a translator between protocols. Even if all your devices use different protocols, a hub can make them “sound” the same. And that’s option # 2.

Another way of doing so is by partnering with 3rd-party providers. There are apps on the market that are designed to unite different smart home apps. Users download apps for all their smart home devices, install a uniting app and then control them all from one place. For example, Yonomi, ONE, etc.
When talking about security in the smart home industry, the main problem is the lack of standards that help to control security levels, which means that it really depends on the company. To help you ensure a great and reliable security system, we’d like to give you some advice on this issue.
Before talking about security features, we’d like to cover a couple of general aspects regarding smart home apps. You can add various levels of access so that there will be less exposure to data leaking. For example, it can be an administrator with the right to manage security and access settings, extract data, etc. An administrator should then be able to add users and give each one of them a specific level of access.
Plus, it’s a great idea to educate yourself on cybersecurity and take a look at others’ experiences. Since there are no generally accepted standards as such, preventing mistakes that other companies have made in the past and learning from companies with trusted security systems is definitely worth it.
To develop a smart home automation system, you can build an IoT mobile application (home automation apps specifically) and enable convenient smart devices control (image by Sulton handaya)
The first thing you can think of enabling is Security by Design. In other words, it’s automating such processes like bugs and breaches testing and monitoring, authentication safeguards, etc. Such a system is focused on preventing security breaches.
We’d also recommend making regular security updates. As soon as you have something to improve in the system, don’t wait until there are more things to update — regular and swift updating is the key to success here.
To make it time-efficient, you can enable Continuous Integration and Continuous Delivery (CI/CD). CI allows you to automatically test the code to find & fix bugs, and then apply changes in the git-repository (you can think of it as a draft for you to test updates). The CD then transfers these changes to the actual code immediately.
Additionally, you can implement multi-factor authentication in your smart home app. It can include biometric authentication like Face ID, fingerprints (scanning all connected devices and notifying users about suspicious activities), complex passcodes that get updated, personal security questions, email/phone number confirmation, etc.
