SAUTER launches ecos504-IoT: an innovative and smart solution for home automation and building automation

With the development of the ecos504-IoT, which uses the Internet of Things (IoT), the SAUTER Group is developing and offering increasingly intelligent, communicative and user-friendly solutions. In this way, SAUTER is achieving the necessary milestones to play a decisive role in the future of building automation, “Smart Home” and “Smart Building”.

SAUTER ecos504-IoT is a new step in building automation: it is now possible to use information via the MQTT protocol directly from public clouds and thus instantly integrate it into the building management and control strategy.

The ecos504-IoT is a programmable BACnet server with an integrated BACnet/MQTT gateway.
It provides and receives BACnet information from clouds via the MQTT protocol. As such, it acts as a gateway between a cloud and technical building automation networks.
An order given from a cloud application can control a BACnet device in the building automation network via the ecos504-IoT. This is thus called a “BACnet Edge Controller”.

The ecos504-IoT solution is based on common developed infrastructures (Internet, access point, etc.), public clouds such as Microsoft Azure, Amazon AWS, Google Cloud and established technologies.

Application examples of the ecos504-IoT

  • Application via speech recognition systems such as Google Home, Amazon Alexa for managing lighting, temperature, ventilation, etc.
  • Smartphone application for remote control and monitoring of home automation and room automation
  • Integration of intelligent sensors into the local building automation network.
