Home Automation: Let’s talk about Security

Home Automation: Let’s talk about Security

The protocol is chosen so that their devices “understand” each other and with their phones is Wi-Fi because it is ” a robust solution that works well, so we have not been complicated by looking for other protocols”. However, there are other protocols for end-to-end solutions that allow you to connect a large number of devices and improve range. They explain that “Home automation systems hardly generate Wi-Fi traffic and thanks to the fact that we have good routers and two networks, one for home automation and one for us, we do not suffer saturation”

In any case, despite the fact that with home automation we can speed up the control of certain devices, the exposure of so many connected devices represents a security risk. How do they solve it? 

Laura and Marcos have an Echo Dot in the bedroom and an Echo Show in the living room and, although they would like to implement another smart speaker in places like the garage, they don’t do it because: “interactions can come from the street. For example, in the garage, someone could give an order from the outside and say ” Alexa, open the door or the window because the voice control is not secured, it is something super light.”

Another of his prohibited devices are cameras: “It makes no sense to put cameras, they are useless, there is nothing you can do. We only put in home automation what makes sense to automate. The” minority Report “concept of I make you a panel that you see your whole house, is to show it to the visitors … you don’t need to see your house, you need to take action quickly “

Although they do have a camera, specifically focusing on the 3D printer “because it is useful when you are away from home how the printing goes to be able to stop it. In one of the axes of the 3D, we have a stick that allows it to be moved remotely.”

The third law prohibits them from accessing their home from outside: “The home automation system is linked to Wi-Fi, but the guests have an independent Wi-Fi that does not have access to the entire system, only to the internet. In this way, inside the home only we have control. We also have a VPN that allows us to access systems from outside the home “

Levels of control and “big data” of home automation

This hobby of your home automation continues to grow according to its usual procedure: they introduce a novelty, they test it thoroughly and when it is stable, they scale it to your home. Despite the experimental and playful component of the process, he details that “we are clear that everything must have a physical backup, or what is the same, I have operational physical switches.”

One of the challenges has been that of the light switches: “we have changed them to push buttons for the sake of simplicity, thus avoiding changes in position if you have several switches in a room. The next step will be to incorporate actions in the pushbuttons For example, if you press the button 3 times in a row, it will do a different action. If I press the enter button once, it turns off the entrance, if I hold it down for three seconds, it turns off the lights in the whole house. “

The physical is the most basic control of your smart home, which is complemented by a panel with buttons in the form of an orderly interface where you will find what you usually need: “it collects the main actions everything that is the living room, bedrooms, the garden”. It is part of a hierarchical structure made up of several levels that depend on the type of order and location :

There is a fourth level that is the computer: “it is the one that allows us to study what we are doing, with a more complete interface.”

Although it is common for manufacturers to give the surname “intelligent” to devices whose differential feature is that they are connected to our mobile phone, Laura and Marcos do seek that intelligence: “We want to include in the project everything that requires an automatic control that It is interesting that it is a bit intelligent, in the sense that it not only has to receive actions that you order but also external information so that it works autonomously “

The set of sensors, processing through the boards, and the Home Automation Assistant management generates an enormous volume of data of great value for the optimization of your smart home automation. Something that has a direct consequence on your energy consumption:
