Smartbox Mini, based on the Telit Chipset HE910 is a ready to use solution for connecting Modbus devices to the Cumulocity. It provides a Master Slave Communication on RS485 for connecting up to 20 devices. Easy configure the configuration of building automation fielddevices like pumps, chillers, E-meters,
Airhandling units in cloud – the Smartbox Mini will take care of it! by automatically picking up the coils and registers and sending alarms, measurements and status information.
