| home_assistant_modbus_tcp_suitable | True |
| home_assistant_suitability_basis | Documented protocol conversion. The USR-DR302 User Manual states 'Modbus RTU and Modbus TCP: Modbus serial protocol to Modbus network protocol can be converted by Opening the Modbus TCP to Modbus RTU function in the web page', with the device 'in the TCP server or the TCP client mode'; the product page's 'Work Mode' row ends '...UDP Client Modbus RTU to TCP'. With a single isolated-rail RS485 port, DIN-rail mounting, IP30 and -40 to 85 degC this is the most natural Home Assistant fit in the DR family. Two configuration cautions: the Modbus TCP-to-RTU option is OFF at the factory, and the factory default work mode is TCP Client with local port 0, so the unit must be switched to TCP Server before a Modbus TCP client can connect to it. PUSR publishes no default Modbus TCP port number. |
