Modbus forwarder #50

Hi, do you have any experience with modbus forwarder? Your extension works pretty well until I try change for example top boiler temperature. The value is not changed in HA, but also it looks like sometimes there is an error on forwarder and sometimes there is no error. I am using modbus2usb for years but currently I have some time to create forwarder to allow connect HA to Nilan. Whereas the forwarder is so simple I am not sure where should I take a look. Do you have any hint? Thanks

I'm sorry. I do not understand the question.

For the Integration to work you need either a rs485 to usb adaptor, FTDI chip based usually work the best, or if wiring is not possible, you can use modbus RTU to ModBus TCP bridge.
