I have an old lighting system that can be controlled over RS485 by sending simple strings such as “\x00\x0E\x01\x00\x00\xF8” etc
Before home asssistant I used to use Roomie Remote and Global Cache IP2SL paired with a RS232 to RS485 converter to send the data. While I still have the IP2SL, I would like to ditch it for some cheaper hardware. My very basic research suggests that it is perhaps possible to use a ESP32 type device paired with a serial converter to achieve this but unable to find more information or a suitable guide for the same. Appreciate any advice. Thanks.
