| home_assistant_modbus_tcp_suitable | False |
| home_assistant_suitability_basis | NOT suitable as a Modbus TCP endpoint. The Waveshare wiki for this model states explicitly 'This module does not support Modbus TCP' and 'It does not support Modbus transmission.', and directs buyers to the RS232/RS485 TO ETH model for Modbus TCP. What this device does is a transparent TCP-to-serial tunnel only - a Home Assistant Modbus TCP client would not get RTU<->TCP frame conversion from it. (A raw-socket / rfc2217-style client is a different matter and is not what home_assistant_modbus_tcp_suitable means here.) |
