| home_assistant_modbus_tcp_suitable | True |
| home_assistant_suitability_basis | Documented Modbus TCP/RTU gateway, and the manual names the Home Assistant topology directly. The USR-M100 User Manual V1.0.1 lists 'Modbus Ethernet-to-Serial support (Modbus/TCP, Modbus/RTU)' in its features, devotes chapter 6 to 'Modbus TCP/RTU gateway', and titles section 6.1 'Ethernet masters with serial slaves', describing a 'Modbus TCP Master' talking to devices in 'Modbus RTU Slave mode'. That is precisely a Home Assistant Modbus TCP client polling RS485 slaves. NOTE THE SEPARATE, DIFFERENT CAPABILITY: the product page's row 'MODBUS RTU master: Supported functions 01, 02, 03, 04' is the edge-computing poller that collects data and reports it northbound over MQTT - that is not the same thing as the gateway mode and does not by itself make the unit a Modbus TCP server. Factory defaults ('Table 6 Default parameters'): 192.168.0.7 / 255.255.255.0 / gateway 192.168.0.1, admin/admin, COM port 115200-None-8-1, COM operation mode TCP server port 23, MQTT Disable, Edge computing Disable. |
