Hi all, i'm tring to connect r4dcb08 module (https://aliexpress.ru/item/1005002616932...1413511247) to the A16 board using ESPHome
Could you please share me some working config (demo config) for A16 board with some modbus device ? (Existing demo codes havn't modbus examles)
Thanks.

i think you can download tasmota firmware, that support MODBUS

I use ESPHome, not tasmota.

1. you should have your device's modbus protocol
2. accroding to ESPHome config: https://esphome.io/components/modbus_controller.html

"No response reciverd" in ESPHome log.
Could you give me 100% working config for a16 board, with correct pins, UART config, etc... Thanks
