Всем привет! Сегодня хочу поделиться опытом разработки универсального телеграм бота для получения информации и управления IoT устройствами посредством протокола MQTT.
Почему (не)очередной? Потому что это не просто бот с двумя захардкоженными кнопками для управление лампочкой, примеров которых в интернете много, а это бот, который поддерживает гибкую настройку подписок и компанд для управления прямо из своего меню, без изменения исходного кода. NoCode solution, так сказать.
Бот разрабатывался на языке Go, исходный код выложен в свободный доступ на гитхаб под лицензией MIT. В статье хочу рассказать о некоторых технических моментах реализации и получившемся функционале с примерами использования.

Everything around us has become smart, like smart infrastructures, smart cities, autonomous vehicles, to name a few. The innovation of smart devices makes it possible to achieve these heights in science and technology. But, data is vulnerable, there is a risk of attack by cybercriminals. To get started, let’s know about IoT devices.
The Internet Of Things(IoT) is a system that interrelates computer devices like sensors, software, and actuators, digital machines, etc. They are linked together with particular objects that work through the internet and transfer data over devices without humans interference.
Famous examples are Amazon Alexa, Apple SIRI, Interconnected baby monitors, video doorbells, and smart thermostats.
When technologies grow and evolve, risks are also on the high stakes. Ransomware attacks are on the continuous increase; securing data has become the top priority.
When you think your smart home won’t fudge a thing against cybercriminals, you should also know that they are vulnerable. When cybercriminals access our smart voice speakers like Amazon Alexa or Apple Siri, it becomes easy for them to steal your data.
Cybersecurity report 2020 says popular hacking forums expose 770 million email addresses and 21 million unique passwords, 620 million accounts have been compromised from 16 hacked websites.
The attacks are likely to increase every year. To help you secure your data of IoT devices, here are some best tips you can implement.
Your router has the default name of make and model. When we stick with the manufacturer name, attackers can quickly identify our make and model. So give the router name different from your addresses, without giving away personal information.
If your devices are connected to the internet, these connections are vulnerable to cyber attacks when your devices don’t have the proper security. Almost every web interface is equipped with multiple devices, so it’s hard to track the device. But, it’s crucial to stay aware of them.
When we use the default usernames and passwords, it is attackable. Because the cybercriminals possibly know the default passwords come with IoT devices. So use strong passwords to access our IoT devices.
Use strong or unique passwords that are easily assumed, such as ‘123456’ or ‘password1234’ to protect your accounts. Give strong and complex passwords formed by combinations of alphabets, numeric, and not easily bypassed symbols.
Also, change passwords for multiple accounts and change them regularly to avoid attacks. We can also set several attempts to wrong passwords to set locking the account to safeguard from the hackers.
Are you try to keep an eye on your IoT devices through your mobile devices in different locations. I recommend you not to use the public WI-FI network to access them. Because they are easily accessible through for everyone, you are still in a hurry to access, use VPN that gives them protection against cyber-attacks, giving them privacy and security features, for example, using Express VPN.
There are software and firewalls like intrusion detection system/intrusion prevention system in the market. This will be useful to screen and analyze the wire traffic of a network. You can identify the security weakness by the firewall scanners within the network structure. Use these firewalls to get rid of unwanted security issues and vulnerabilities.
Every smart device comes with the insecure default settings, and sometimes we are not able to change these default settings configurations. These conditions need to be assessed and need to reconfigure the default settings.
Nowadays, every smart app offers authentication to secure the accounts. There are many types of authentication methods like single-factor authentication, two-step authentication, and multi-factor authentication. Use any one of these to send a one time password (OTP) to verify the user who logs in the smart device to keep our accounts from falling into the wrong hands.
Every smart device manufacturer releases updates to fix bugs in their software. These security patches help us to improve our protection of the device. Also, update the software on the smartphone, which we are used to monitoring the IoT devices to avoid vulnerabilities.
When we connect the smart home to the smartphone and control them via smartphone, you need to keep them safe. If you miss the phone almost, every personal information is at risk to the cybercriminals. But sometimes it happens by accident, makes sure that you can clear all the data remotely.
However, securing smart devices is essential in the world of data. There are still cybercriminals bypassing the securities. So make sure to do the safety measures to avoid our accounts falling out into the wrong hands. I hope these steps will help you all to secure your IoT devices.
If you have any, feel free to share them in the comments! I’d love to know them.

For data exchange with constrained devices and server applications, MQTT is the top choice of large enterprises around the world. You are just as likely to find MQTT connecting things in your living room, in a car as within a factory. MQTT’s widespread adoption has led to its acceptance as an open OASIS and ISO standard. Today, MQTT is the absolute standard protocol for the Internet of Things (IoT) worldwide (see Google Trend Chart).
In 2015, HiveMQ wrote the MQTT essentials blog series. A new article introducing the core concepts of MQTT was published every Monday - that was the beginning of the MQTT Monday. By explaining the features of the protocol and other essential information, our aim was to provide easy access to the subject. The idea was to make it easy to understand and implement MQTT quickly and successfully.
Five years later, our blog series is still very successful. That’s why we want to make the MQTT content even more accessible. We are happy to announce that MQTT Monday is back - this time in video format. Every Monday, from now on, we will publish a short MQTT Essential video on our YouTube Channel. Our new series of videos will provide a basic understanding of the MQTT protocol and will familiarize everyone with the MQTT protocol without reading the full specification.
There’s a lot going on in the MQTT world right now: With the release of MQTT 5, the most feature-rich update to the MQTT specification ever, new features such as session & message expiry intervals, improved client feedback & negative ACKs, payload format description, and many more, have been introduced. The industry initiative “Sparkplug” has evolved to define a common MQTT data specification to promote interoperability between device manufacturers and SCADA vendors. We believe this is just the beginning. Over the next few years, we expect continued massive growth of MQTT application in all industries, including manufacturing, automotive, critical infrastructure, logistics, smart cities, etc.
HiveMQ will continue to provide high-quality content that helps developers understand and adopt MQTT for their IoT applications. Keep watching our Youtube channel or subscribe to our newsletter to keep up to date on the latest news.
