Wbox S103 is an industrial universal control unit. It is running on a raspberry PI 3 board, hence it has a low power consumption and good hardware performances. The operating system is Raspbian with accomodations to control the inputs/outputs, and rs485 port. In combination with our software suites, it’s an ideal solution for control and regulation of smart building systems, HVAC systems, industrial automation and others. The unit can also be utilized for energy consumption monitoring, data collection, cloud storage, or as a gateway between various protocols and equipments (boilers, heaters, actuators, sensors etc.).


The S103 is CE and EMC tested. According to standard, all Weble products can be used in:

  • Residential buildings, apartments
  • Commercial areas, offices, banks
  • Entertainment areas, cinemas, bars, pubs, dance clubs
  • Outdoor places, gas stations, parking lots, sport centers
  • Areas of light industry, workshops, laboratories, service centers


The S103 can be customized and custom OEM branding on the enclosure is possible. It is possible to use the S103 either with Weble building automation softwares, or with your own custom softwares / any open-source softwares developped by the Raspberry community. Contact us for more information.
