Thanks for the reply but I still can not understand what I have to do. Could you help me?
I follow…
I tried to do a lot of tests.
I changed the register, but I’ve never been successful.
For the register I followed these links:
https://forum.logicmachine.net/showthread.php?tid=1403
Some registers are in the comments.
What am I doing wrong?
I saw that the communication LED sometimes flashes.
This is the last code loaded:

Please can someone help me?
Thank you very much.
I have the same problem.
Has anyone got the solution?
This equipment accect function Preset Multiple Registers (FC=16), but the HA write registers whith de function Preset Single Register (FC=06).
Has anyone know implement this function in HA?
I found a solution that works but I do not get feedback from the relay module.
I wrote a script in python, which uses the mobuspy and is called by a button in the homeassistantt with command line.
My file calls 8O.py, and the id RS485 is 7.
My scripy in python:
#!/usr/bin/python
#---------------------------------------------------------------------------#
# import the various server implementations
#---------------------------------------------------------------------------#
from pymodbus.client.sync import ModbusTcpClient as ModbusClient
# from pymodbus.client.sync import ModbusSerialClient as ModbusClient
from pymodbus.transaction import ModbusRtuFramer as ModbusFramer
#---------------------------------------------------------------------------#
# configure the client logging
#---------------------------------------------------------------------------#
import logging
import sys
# parametros de entrada
relay = int(sys.argv[1])
value = int(sys.argv[2])
logging.basicConfig()
log = logging.getLogger()
log.setLevel(logging.DEBUG)
#Define Modbus Target Device
client = ModbusClient(host='192.168.1.10',port=502)
connection = client.connect()
print (connection)
# send write command to modbus server
#600= off 300 = on
register_value = client.write_register(relay, value, unit= 7)
client.close()
#---------------------------------------------------------------------------#
In configuration.yaml:
- platform: command_line
switches:
switch_1:
command_on: ‘python3 /config/8O.py 1 300’
command_off: ‘python3 /config/8O.py 1 600’
Please please follow the instructions at he top of the page and format your code properly.

hi i bought a modbus RTU relay (WAVESHARE).
i installed usb adapter in a raspb (it should be recognized directly as i read in posts.
to activate realay 1 I have to send a hex: 01 05 00 06 FF 00 6C 3B.
How can I do?
thanks
I tried to read.
But how i send a hex 01 05 00 06 FF 00 6c 3b to activate the relay?
Are you sure this is modbus?
Yes.
I use “register” and “command on” but don’t work with 01 05 00 ecc.
I managed to activate the relays using the -call service- function:
modbus.write_coil
unit: 1
hub: hubrelay
address: 2
state: 1
but in my case -switch- and -binary sensor- of -modbus- don’t work
so I can’t read the status of the relays
What is your binary_sensor: yaml?
In configuratio.yalm…
binary_sensor:
- platform: modbus
inputs:- name: Sensor1
hub: hubrelay
slave: 1
address: 3
- name: Sensor1
a function as well as read coil?
I don’t know how to guess the right numbers for slave and address. But please read this and quote your code properly. How to help us help you - or How to ask a good question
