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.

to be able to help
Load the controller Modbus sheet.

if you can't use ethernet, i suggest you use wifi, it's easy.
in our A16 ESPHome config file, you just need delete the ethernet config content, replace with your wifi router's ssid and password, such as add these text:

wifi:
ssid: "KinCony"
password: "a12345678"
