hi. I'm communication systems engineer. I have 5+ years of experience in software-hardware integration. I have worked a lot with Modbus protocol and MQTT. I have interfaced a variety of hardware with my applications. here are a couple of my past projects: ---( https://www.freelancer.com/jobs/project-16686999/ )--- and ---( https://www.freelancer.com/jobs/project-16338099/ )--- I can show you more. I'm very interested in working with you on this project. let's discuss further and do it. waiting for your response...

Bid is proxy, until requirement specifications completed. - modbus: Original (a)sync, or via TCP ? - intermediate "converter" OK, like openwrt-box, to convert modbus<->mqtt ? - which functions ? (READ, WRITE registers only ?) As a good old German engineer, I also used an original MODICON PLC, long time ago :-)

Need to discuss project requirements in more detail. I AM AVAILABLE HERE FOR DISCUSSION. Thanks & Regards.
