TapHome Control unit (Core) can provide information about devices to other control unit or central building management system. This communication is bi-directional, therefore also devices can receive commands from external environment.
To provide high level of security, you have to enable this feature for specific devices. In Menu → Settings → Expose devices, you can define interface for connecting TapHome with 3rd party systems. Available interfaces:
Amazon Alexa (Enable voice control of TapHome devices via cloud connection with Amazon Alexa)
Modbus RTU (over RS485 wire • Connection established via BUS1, BUS2 or BUS3 terminal on Core
Modbus TCP (over TCP/IP network • Connection established via LAN cable)
KNX (over KNX protocol • Connection established via KNX Gateway, that is communicating with Core over TapHome Bus)
