the measured value with a preset value in the application), an alarm is triggered, and three messages are generated. One of them is sent to the television, and a window opens that indicates the reason for the alarm (see **Figure 13**). Another message is sent to the web application, indicating the type of alarm and the monitored patient. Finally, a third message is generated by the web application that sends an e-mail to the consultant physician (see **Figure 14**). • Fall detection: every time the fall detection module installed in the smartwatch detects a fall event, an alarm is triggered, and three messages are generated. One of them appears on the smartwatch screen (see **Figure 15**). Another message is sent to the web application, informing about the type of alarm and the monitored patient (see **Figure 16**). Finally, the

third message is sent by e-mail to the consultant physician (see **Figure 17**).

The success of the treatment of the chronic patient is directly related to the execution of the care plan prepared by the health team for the patient. Scientific evidence indicates technology

The boost in health technology in the context of the Internet of Things (IoT) in recent years has

However, their dissemination among the population remains a great challenge. Most existing solutions are proprietary and difficult to integrate. While the Internet of Things (IoT) occupies an increasingly larger space, the lack of Internet in Brazilian homes prevails. Although wearable devices are becoming fashionable, devices certified for monitoring patient health conditions and for data transfer are rare. In Brazil, during this study, only one blood pressure metre met these requirements, whereas the main brands of blood glucose metres have versions available in the market with ease of communication and proprietary applications to help in controlling blood glucose levels. Despite the demand for health solutions and services using the IoT, much work lies ahead regarding the establishment of standards and requirements for IoT platforms. In this study, we sought an original solution for the problem of chronic patient monitoring combined with the need for compatibility with televisions and with the possibility of interaction with smartphones and other wearable devices. Typically, studies based on IoT are limited to the development of a new smartphone application that implements the patient care

plan and devices that measure either the blood glucose or blood pressure levels.

The study suggests that the starting point for using this technology is the consultant physician, who prepares and loads the patient care plan to the gateway that will be installed in the patient's home. The availability of wireless networks does not prevent the gateway from alerting the patient about tasks and collecting the data from the blood glucose and pressure metres. User authentication is crucial for data security, which was achieved by a practical and secure

Conversely, integration with smartphones and wearable devices, such as smartwatches, was also implemented because these options enable the user to move while maintaining the support
