@Heine_Madsen It lookls like you have configured a sensor as a switch possibly?
Could you post your modbus config for this device please?
Hi,
This is from my configuration.yaml. The last one is my dimmer (Register 1129).

@Heine_Madsen quick reply…cheers!

register: 1129
command_on: 1
command_off: 0
state_on: 0
Not that I can confirm myself as I don’t have any modbus dimmers to test.
BUT…state_on: 0 is a problem I believe
If as you say it is returning
Then that indicates to me this register should be addressed as a sensor. You also should be able to write to it as well (to set the dimmer value)
Also from the Modbus Switch docs…
state_on
(integer)(Optional)
Register value when switch is on.
Default value:
same as command_on
I believe you may need to rectify that?
My bad… state_on was a leftover from some testing.
Tried to put an expression there like “>0” to indicate that any value above 0 is on.
Will try to look into the sensor thing
A dimmer should consist of a switch and a sensor it seems to me?
Switch = on or off
Sensor = dimmer value
Again I have nothing to test so I could be wrong.
@wellsy thaks alot for the input…
Now i can read the correct value by a sensor.
Just have to figure out how to create a light with dimmer in lovelace and the… any hint’s and tips? 
Excellent!
@Heine_Madsen Now…You need to setup writing to the sensor/modbus register.
That involves two new config items:
An input_number to choose a value to be set
input_number:
slider2:
name: Sludge Pump Restart Delay
initial: 30
min: 20
max: 60
step: 1
and then an automation to write your modbus register
- id: SludgePumpRestartDelay
alias: Sludge Pump Restart Delay
trigger:
platform: state
entity_id: input_number.slider2
action:
service: modbus.write_register
data_template:
hub: hub1
unit: 1
address: 3092
value: "{{ states.input_number.slider2.state|int }}"
EDIT: Then put the switch the sensor and the input number all on a lovelace card
Hi again…
Just need some clarification on the lovelace thing.
i need to define it as a normal modbus switch and a modbus sensor and a input_number?
how would i add it to lovelace card? as a light? or which card type?
I somehow managed to get it on to lovelace now…
but i have one issue… it shows as if it’s off 
Any hints and tips?

@Heine_Madsen FIRST your config looks to be good… fyi “slider2” is just my name for that input_number…you can call that what you want but must adjust accordingly here as well:
value: "{{ states.input_number.slider2.state|int }}"
Next is the dimmer working atm? IE: you can change the brightness?
The switch advice I gave may be wrong? Maybe you just set the dimmer value to ‘0’ OR is there another register or a “coil” which is the switch for the dimmer?
Do you have a manual or other documentation to refer to or do they have tech help/support?
PS: I just use an entity card in lovelace:
- type: entities

show_header_toggle: false
entities:

Hi @Heine_Madsen, I’m like you have a Hassio --> Carlo Gavazzi Smarthouse (SH2WEB24) Set up in my house. I have not been able to find any information about how to connect the SH2WEB24 with Hassio and it seems there in’t much about it on the web.
Is there any chance you can help me in the right direction how you configure HAssio and SH2WEB24 to communicate?
Best regards M
Hi…
Sorry for late reply…
Did you manage to get thing working? If not, then let me know and i will try to assist.
/Heine
Hi again, Sorry for late replay from me to. No I have not mange to get things to work. I know how to set the SH2WEB24 as slave but don’t know how to retrieve info about things called coils and register.
So aim stuck
@Heine_Madsen hi!
I have the same carlo gavazzi controller for my smarthome but I have not managed to integrate with hassio… I have however managed to build a python/modbuslib script to read and control lights based on function 1 and 5 accordingly.
I tried to follow your setup to move everything to hassio but I cannot understand where to find the registers that you used (ie. 119, 143 etc). Based on my setup (and smarthome configurator help file), function 5 used input coils with addresses 5376-5503.
More specifically in my setup, I have for instance the “Living room Spots” which I call function 1 to register address (dec) 1333 to read (dupline address G6),and function 5 with register address (dec) 5442 (dupline address I3) to toggle.
Can you please let me know how to find these (working) registers in my setup or how to convert the function 5 register address to hassio?
Any other help would be greatly appreciated, I really need to move the python/modbuslib setup to hassio…
Thank you!
George
One question here, my configuration is following:
modbus:
name: wago
type: udp
host: 192.168.1.2
port: 502
sensor:
registers:
- name: light
hub: wago
slave: 1
register: 12310
register_type: holding
count: 1
scale: 1
offset: 0
precision: 0
data_type: int
input_number:
target_temp:
name: Target Heater Temperature Slider
min: 0
max: 3
step: 1
unit_of_measurement: bulbs
icon: mdi:target
automation:
- alias: Send from slider to modbus
trigger:
platform: state
entity_id: input_number.target_temp
action:
service: modbus.write_register
data_template:
hub: wago
unit: 1
address: 12310
value: "{{ states.input_number.target_temp.state|int }}"
- alias: Read from modbus to slider
trigger:
platform: state
entity_id: sensor.light
action:
service: input_number.set_value
data:
value: "{{ states.sensor.light | int }}"
And almost everything works. I can send value to modbus and read it back. sensor.light updates when I change the value on modbus side. I just can’t get to update slider with value I set on modbus side. Any help appreciated.
Hi Guys,
You seem to have quite an experience with the modbus module. Can you perhaps help me with my issue?

Thank you in advance,
Regards Matt
Hi, Any guys still active here ? I’m going to integrate this, but don’t know where to find the register addresses ? Any hints, maybe, someone who can post working configs on a dimmer configuration ?
And also, it seems like it’s necessary to enable modbus on the controller. Where to do so ? I have access with the programming software already
