Guys any ideas ?
Yesterday I have run new instance of Openhab 1.8.3 on my PC, connect via same USB/RS485 interface and it worked. In fact in the beggining it was not working then I change in config modbus name from capital letter to small and it started to work.
Today I backed to Pi, change letters, so config is same (except COM and ttyUSB0) and still “failed to read: Error reading response” 
I have removed all other modbus config, just left new one for meter same result.
connection is working, because when I launch python script it is working.
