In this paper is presented an user interface and a communication platform for a modular home automation system. Its main objective is to contribute to the comfort and autonomy of users who suffer from some type of disability. At the same time, it proposes to give a simple and economic solution to the problematic of the accessibility, since although there are many options of automation in the market, are few the options to centralize the control of the different home equipment. Also, the system does not require Internet to operate, thus it is another advantage in countries where the mobile 4G Internet is not a standard.The user interface has been developed using a speech recognition module which allows the identification of commands from different users. The communication of the modules is via WiFi and was implemented using the ESP8266. This integrated hardware complains the 802.11 standard, contains the complete TCP stack and has a programabe microcontroller.Two protocols were exclusivelly developed, one for the association of the modules to the WiFi network and another for the communication of the different nodes involved in the home automation system. Both are based on the IoT (Internet of Things) approach and give the system decentralized communication. Although it does not require internet connection, optionally the system has the platform to establish a remote access.
