| home_assistant_modbus_tcp_suitable | True |
| home_assistant_suitability_basis | The generated datasheet prints two separate role rows: 'Modbus-RTU Mode: Client / Master' (Serial Features / Modbus-RTU Features) and 'Modbus-TCP Mode: Slave / Server' (Modbus-TCP Features), with 4 concurrent Modbus TCP connections. The device therefore polls serial Modbus RTU slaves as master and presents the result to a standard Modbus TCP client as a server, which is what Home Assistant's modbus TCP integration needs. Caveat recorded from the same datasheet: this is a configured data-mapping gateway (fixed input/output data areas of 1500 bytes each), NOT a transparent request-forwarding RTU-over-TCP bridge - a Home Assistant client reads the gateway's mapped register area, not arbitrary slave registers. No default IP address and no Modbus TCP port number are printed on the datasheet. |
