"Home automation to make yourself", I tried using it from an engineer perspective!

How far can the current home automation "play"?

　Recently, "Smart Home" equipment that can control ON/OFF in cooperation with smart speakers such as Amazon Echo and Google Home has shown signs of spread.

　However, if you are familiar with IT technology, you will notice some shortcomings.

　First, if the manufacturer is basically different, there is no interconnection.Once you buy a smart home device from a specific manufacturer, you must unify the device with that manufacturer.Even if an attractive device is released from another company, it cannot be connected.It is a so -called "vendor lock -in" problem.

　Vendor lock -in is not just a matter of "narrowing product options", but sometimes "product support stops due to manufacturers."It's hard to be able to use a smart home device that has been set up hard in a few years, and you have to buy a new one for another company.

Part 1: "Make things that are not!" What does "mania" aim for home automation on his own? The second part: "Technology is not well known but" content ", so I want to create a community."

　You may also be worried that the system is a black box and it is difficult to solve your troubles yourself.Also, it is frustrating that "within the range prepared by the set, you can easily achieve various functions, but you can not exceed it even a little."Even if you want to improve it with a little hand, it doesn't go.

　Furthermore, it is also worrisome that it is a little weak to introduce to a business that manages a large amount of air conditioners and lighting for home for home.Nevertheless, the high reliability system for business establishments is very expensive and the hurdle of introduction is very high.

　Working on these issues is a startup that aims for a truly free home automation (HA) that does not depend on the cloud or specific companies.

　For the company, the company has already published an interview article (Part 1 / Part 2), and Critica's HA solution "CL-SYSTEM" is "MQTT" protocol, "Openhab 2", which is an open technology for HA.Based on highly obtained devices such as "M5STACK".

　Although it is necessary to learn a little, if you understand, you can build a "smart home" solution independently, and you can build a "home automation" that automates processing by linking sensors and devices at a relatively low price.

　So, this time, I would like to explain how to introduce CL-System for "people who are interested in technology".I wrote it for those who are not reluctant to operate on the command line, and for those who want to understand new protocols and concepts, and want to know the inside of IoT equipment, please read it.。
