You can already hook up an RS-485 transceiver to the UART ports and use it today with the UART driver.
Esphome also has a Modbus controller component. What are you referring to by “generic” RS-485 that isn’t available already?
- cyberax 2y agoRS-485 is a shared bus, so you need to use some kind of a protocol to arbitrate access, and to make sure you don't flash unintended devices. BACnet is one example, but other protocols can work too.
