@djairguilherme said in New ESPHome Support for M5StamPLC: Thanks ChirpyChips aka @Beormund. I used your implementation with ESPHome to interface with a Schneider Phase Inverter. I wrote a tutorial on Hackster.io. https://www.hackster.io/nicolaudosbrinquedos/m5stack-stamp-plc-as-real-plc-3ec3ed Thank you very much for your work! @djairguilherme Nice! At some point I really do need to utilise ESPHome's RS-485 support to expose the M5StamPLC's PWR-485 interface as a Modbus slave. It's on my TODO list.
