ESPHome Modbus config for KC868-A6

[aucirc]

sorry, i don't know the "WP3082ADAM". maybe you can use USB-RS485 adapter to test firstly. when you send command manually and check whether have feedback. if OK, then test with ESPHome.

Yes have already done this - sending the same command and seeing the same response:



Just having issues getting ESPHome to hear the response.  Can you confirm if I have the correct GPIO pin assignment for RS-485 on the KC868-A6?

uart:
  id: mbus
  tx_pin: GPIO12
  rx_pin: GPIO13
  baud_rate: 9600

I couldn't find this information for A6 anywhere and referred to the schematic.
