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 :-)
