        Hi all,

        My workplace is purchasing a new TriOS Opus nitrate sensor, and I’m wondering if I could get this working with the Mayfly.

        https://www.hydrotechzs.com/downloads/opus-manual.pdf

        It communicates via MODBUS RS-485, so I figure my DIY modbus wing should be able to facilitate communication.  However, I don’t really know where to begin after that.

        Can anyone provide any pointers or code that could get me started?

        Thanks for your help.

        James
