Could you share your config where I can see how you triggered max air ( changing value) ? Or you just set boost mode? 
Cool, so you just connect the main unit to the LAN and you can communicate over modbus protocol, right?
Does it have any sensor, example for cooking so it turns the vent to the maximum? Or you must turn it on manually?
Yes just connect to the lan. Also you could change paramters via phone app.
I also canât understand how to set maximum value for the vent. Maybe someone will help us

Cool. For the max value: canât you use some network sniffer to check how the app communicates with the main unit?
I donât know if it helps, but I requested modbus protocol from Komfovent:
Thats really nice. Could you please share configuration.yaml and Lovelace?
Max air you can trigger by external wired circuit contact.
I use HA. If light ON, then boost for some time recuperation.
Hi, i used narnaliai setup and just edited it a bit.

Hello.
Did anyone figure out how to control temperature (Register name - Setpoint)? I am able to change Supply/Extract flow values from HA but not temperature. Maybe it has something to do with Data type being signed short.

Hi!
Updated to newest home assistan and chekced in the logs. There were several modbus warnings (Sensor configuration is deprecated, will be removed in a future release).
Looks like there is a new style of modbus configuration.
You can now use the new style configuration when configuring the modbus integration. The existing configuration style is kept, allowing you to change gradually.
Remark the existing configuration style will be removed in a couple of releases.
Example of an existing configuration:
modbus:
- name: "hub1"
type: tcp
host: IP_ADDRESS
port: 502
sensor:
platform: modbus
registers:
- name: "Sensor1"
hub: "hub1"
unit_of_measurement: "°C"
slave: 1
register: 100
Same configuration in new style:
modbus:
- name: "hub1"
type: tcp
host: IP_ADDRESS
port: 502
sensors:
- name: "Sensor1"
slave: 1
address: 100
modbus docs: Modbus - Home Assistant
Has anybody already converted the configuration code to new style and can share it?
After latest update buttonsfor power ,eco and auto wend to be not availbleâŠ
Is this a case of ânew styleâ modbus configs ? Are somon already have new and can share
Same here.
I did automation to tackle the lack of settings for summertime use of the ventilation. Komfovent is lacking the ability to dynamically change the ventilation taking account of room temperature. So in the daytime, when itâs hot outside and inside, it blows the hot air inside. Mine has a free cooling functionality, but this can be set only to supply temperature. If you set supply temp to 22 degrees, free flow tries to keep it that way and if room temp is 25 degrees and outside temp is 17 degrees, it does not allow cooler air than 22 degrees to supply. So i have set the supply temp to 5 degrees, to ensure getting as low supply air temp as possible.
Now other thing is that i donât want is normal flow when outside is hot and inside is hot and cool the house when outside temp is low and inside is hot. This happens in the evenings and night. So depending on the inside temp I want to to cool either on normal (65/65) flow or intensive (80/80), when itâs really hot (over 35 degrees).
I game up with a automation I would like to share, so maybe somebody else can tackle the same supper hot issue:
