| home_assistant_modbus_tcp_suitable | True |
| home_assistant_suitability_basis | the model's own Waveshare wiki hardware-parameter table names the product type 'Modbus Gateway' and states 'Support Modbus gateway function, support Modbus RTU to Modbus TCP'; the wiki's Modbus configuration section gives Modbus TCP port 502. That is documented RTU<->TCP protocol conversion, not merely the transparent TCP-to-serial tunnel the same device also offers. Waveshare does not itself document Home Assistant or Node-RED integration - the basis here is the documented Modbus TCP server behaviour a standard Modbus TCP client can use. |
