16 channels through esphome modbus communication.

[2sdaymars]

I am currently trying to connect a controller with 16 channels through esphome modbus communication.

https://esphome.io/components/modbus_controller.html

Tried with this example but failed.

uart:
  id: mod_bus
  tx_pin: 17
  rx_pin: 16
  baud_rate: 115200
  stop_bits: 1

Are the tx and rx pin numbers correct?

What part should I edit?
I really need your help.
We are preparing a plant factory, so if this succeeds, we plan to continue ordering 16-channel boards in the future.
