Rs485

[Savino]

MUST need use RS485 for connection? if use by wifi will be very easy.
let server-mini and A6 connect to same router is ok. install ESPHome, config yaml file for A6.

Hello admin.
I used wifi and it's all ok.
I'm able to set relay and read digital input from my A6 board connected to homeassistant.

Now I need to setup communication beetwen Mini Server and A6 board via RS485.
I followed the video you suggested. Something is not working and I hope to solve the problem step by step.

So first of all: in the Mini Server yaml file there is something wrong.
I receive the following notifications from Home Assistant:

Invalid config
The following integrations and platforms could not be set up:

• uart (Show logs)
  
• modbus_controller (Show logs)
  
• modbus (Show logs)
  

If I go to the logs, briefly the messages are:
integration 'uart' not found
and invalid config for modbus...for exemple id is an invalid option for modbus and so on

could you help me?
