Is It Safe To Expose Home Assistant To The Internet?

This article will discuss best practices for securing your Home Assistant and why it is crucial not to expose it to the internet. Furthermore, we’ll outline the risks of exposing your device on the network, ways to secure your Home Assistant, common signs of a hacked smart home, and what to do in case of a hack.


The Benefits Of Smart Homes

Smart homes offer a modern and convenient living experience that homeowners can customize according to their preferences.

Home assistants such as Google Home or Amazon Alexa can operate multiple smart devices in your home, allowing you to control everything with just your voice.

Smart thermostats and lighting systems are energy-efficient and eco-friendly, making them popular among homeowners.

Risks Involved With A Smart Home

As with anything connected to the internet, smart homes are susceptible to cyber-attacks. A hacker can exploit a smart device’s vulnerabilities and gain control over it.

Once an attacker has access, they can steal sensitive data, install malware, and even bring down your entire network. Consequently, it’s essential to secure your devices to prevent such situations.

Why Is It Not Safe To Expose Home Assistant To The Internet?

A. Potential Risks Involved

Exposing your Home Assistant to the internet may lead to untold risks. Malicious individuals can exploit device vulnerabilities to steal your sensitive information and gain unauthorized control over your device, putting your privacy at risk.

B. Ways Hackers Can Exploit Smart Devices

Hackers can attack your smart devices in different ways. They can create malicious software to infiltrate your device’s network, extract personal data, and even launch a distributed denial-of-service attack. Additionally, some hackers employ social engineering, tricking users into giving them access to their Home Assistant accounts.

C. Cybersecurity Measures To Take

There are various cybersecurity measures you can take to protect your Home Assistant. You can start by following basic security principles, such as using strong passwords, updating your firmware, and enabling two-factor authentication. Keeping your Home Assistant on a separate network helps to secure it from potential threats.

How To Secure Your Devices

A. Using Secure Passwords

Creating strong passwords is a crucial step in securing all your smart home devices. You should use a combination of uppercase and lowercase letters, numbers, and special characters when creating your password. Additionally, avoid using common words or phrases to secure your passwords.

B. Updating Firmware

Regularly updating your Home Assistant’s firmware is necessary to address any vulnerabilities. Firmware updates typically contain security patches, so not updating them may leave your Home Assistant vulnerable.

C. Enabling Two-Factor Authentication

Enabling two-factor authentication means that your Home Assistant account will require two authentication methods to access. An excellent example of two-factor authentication is a password and automatic SMS verification.

D. Creating A Separate Network

Creating a separate network to host your Home Assistant provides a layer of security for your smart home devices. It separates them from the rest of your home network and gives you more control and oversight over your device’s security.

Common Signs Of A Hacked Smart Home

A. Malicious Behavior

Strange noises and unexplained device activity are signs of a smart home hack. If your device operates outside of its usual behaviour, you may have been hacked. Instances where a smart speaker suddenly speaks on its own or your digital photo frame starts showing offensive images indicate a breach in the network.

B. Unusual Network Activity

On your home network, devices communicate with each other continuously, so any unusual activity on your network could indicate that your smart home has been hacked. You can use network monitoring tools to track your network activity and identify potential data breaches.

C. How To Recognize An Intrusion

If your device was hacked, you would notice changes to your device’s behaviour, network traffic, or unknown entries in the login history. Additionally, check your browsing history and social media profiles to ensure that no one has used your account inappropriately.

D. What To Do In Case Of An Intrusion

In the event of an intrusion, it’s essential to act quickly to minimize any damage. Disconnect your home network from the internet, change all passwords connected to your Home Assistant, reset the device to default settings and perform a factory reset.


Securing your Home Assistant is essential in optimizing your smart home system. The risks of exposing your Home Assistant to the internet are significant, and it’s essential to take measures to protect it from hackers. Ensuring your smart home devices remain safe preserves your privacy and ensures the security of your data.

Staying vigilant and taking proactive actions to secure your devices will prevent cybercriminals from hacking your Home Assistant. Proper cybersecurity measures reduce the overall risk of a smart home or smart device breach.
