home_assistant_modbus_tcp_suitable False
home_assistant_suitability_basis The gateway's field side is CAN (CANopen, J1939, proprietary CAN 2.0A/B), not serial Modbus RTU - the NONE-forcing read confirms no RS-232/422/485 row exists in the Specifications. It does act as a Modbus TCP Server, so a Modbus TCP client can read it, but it does NOT expose a serial Modbus RTU device, which is what this flag means.
