Multitech

1.Introduction #

The Multitech gateway is a key component in connected solutions developed by EWATTCH. Designed to meet the needs of companies in their energy transition, this gateway integrates advanced IoT technologies, including the LoRaWAN protocol, ensuring reliable and high-performance connectivity. Thanks to its software developed by EWATTCH, it stands out for its ease of deployment and its seamless integration with the EWATTCH Cloud platform. This synergy not only enables the collection and transmission of data from various sensors, but also allows it to be intelligently used for monitoring, analysis, and optimization of systems. In addition, the Multitech gateway includes a schedule-based control feature. With this innovation, it is possible to program and automate the control of specific equipment according to predefined schedules. This capability enables proactive and efficient resource management, contributing to significant energy savings and improved operational performance.
