close_comm_on_error:
description: Determines if the modbus communication is closed when an error occurs, default is true. Some serial-rs485 adapters send garble to HA when opened, this leads to a disconnect and a new connect, which can continue. If in a running communication the debug log contains a message from pymodbus, with the text "cleaning....", then try this parameter.

default: true

delay:
description: Time to delay messages in seconds after connecting. Some modbus devices need a delay typically 1-2 seconds after connection is established in order to prepare the communication. If a device accepts connecting with no response to the requests sent or the device disconnects, this parameter might help.
