| home_assistant_modbus_tcp_suitable | True |
| home_assistant_suitability_basis | Documented protocol conversion. The USR-DR301 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', and the product page's 'Work Mode' row ends '...UDP Client Modbus RTU to TCP'. The conversion is a web-UI option that is OFF at the factory. Two important cautions: (a) the factory default work mode is TCP Client to 192.168.0.201:8324, not TCP Server, so the unit must be switched to TCP Server before a Home Assistant Modbus TCP client can connect to it; (b) the serial port on this model is RS232 per the product page and product title, which does not reach an RS485 Modbus RTU device - see the review entry on the manual's conflicting RS485 wording. |
