Thanks. Arrived okay.
Another site provided a really good instruction sheet.
Send AUTO and it outputs the temperature and humidity.
I used a WebSerial Web Page to send modbus commands.
These triggered a response.
bytes = new Uint8Array([ 1,4,0,1,0,1,0x60,0x0A ]); worked temperature
bytes = new Uint8Array([ 1,4,0,2,0,1,0x90,0x0A ]); worked humidity
console.log( bytes )
await this.writeUint8Array(bytes);
