The etymology of the word safety means: lack of danger; feeling of peace and confidence; shelter from any danger; feeling of security. A security system of goods, values and protection of people can be implemented through an automated platform, under the name of Home Assistant. This server software application can communicate with an easy control system for fast and two-way access, which can be mounted to a restricted main entrance. The automatic opening of the access door is controlled both by stand-alone RFID (Radio-Frequency Identification) modules, which act on an electric closing mechanism, and by an automation system configured in the Home Assistant application. The ultimate goal is the security of the premises through a system that can operate both locally and online via internet connection. The research methodology was based on the study of intelligent applications for residential access, described in the literature, aiming at integration into the open-source HA platform, by developing new code sequences. I come with this paper in support of those who want to bring an improvement in the existing automation system, respectively to encourage those who want an automated residence at a higher level. 1 Introduction Information and technology are growing exponentially, in an accentuated rhythm. The technological environment creates opportunities to improve lives by modeling electronic devices with sensors. Automation systems are found in more and more areas of everyday life. Also, even jobs are influenced by technological changes, namely automation / digitization [1]. By modernizing the technology there is an increase in productivity and quality of the final product. There is a wide variety of smart devices on the market, such as: switches, sockets, bulbs, presence sensors, surveillance cameras, temperature, and humidity monitoring devices, etc. Almost any manufacturer of electronic equipment with WiFi connection also offers a customized application, with access and control from your mobile phone or computer. This is a disadvantage if you use more than one device from different manufacturers. In order not to be forced to use only equipment from the same * Corresponding author: laurentiu.munteanu@insemex.ro SESAM 2021 MATEC Web of Conferences 354, 00008 (2022) https://doi.org/10.1051/matecconf/202235400008 © The Authors, published by EDP Sciences.
