You will have to write a driver for it if you cannot configure and use the modvfd driver. If you want to read more data than supported by a driver you can add a plugin for that or write a more advanced driver.

Looks like it will probably work with ModBus RTU and the modvfd driver, your challenge may be getting the register definitions.. The vendor manual for the YX9000 says "see chapter 9", and then conveniently stops after chapter 8 😁

The manual for another model (YX3000) does include ModBus RTU register definitions though, so that would be my starting point.

If I was doing it, I would hook it up to a PC with a USB-RS485 adapter, and use pymodbus to verify everything first.
