Most likely cause is wrong device path. Other is A and B wires connected opposite or missing termination resistor.
Go to settings->system->hardware->"three dots"->all hardware
Find the correct usb adapter. Copy path.
Missing ground wire could also be one cause.
Thank You! Issue solved. I had physical wire connection problem.

You are most welcome.
I would be interested in your device bus version. If you could kindly report it here #9. Thanks.

Should one still be able to run following type of holding register services even your perfect HACS is active? Looking to build Nordpool sensor triggered automations w/o python skills, but e.g. below service does not turn PILP off:
service: modbus.write_register data: address: 1001 slave: 30 value: 0 hub: hub1
Trying to create serial connection to Nilan, but getting error "invalid response from device".
Setup
...any thoughts?
