Hi,
Played with V300 C8 controller. If anybody need Komfovent external CO2 sensor (connected to C8 terminal pin 3-5 with wire) I managed to get the reading out by adding this sensor:
# Komfovent CO2 air quality sensor
- name: "Komfovent Air CO2 sensor 'ppm"
address: 951
data_type: uint16
scale: 1
unit_of_measurement: "ppm"
state_class: measurement
scan_interval: 30

Is it possible to use komfovent switches in automations? I don’t see them in the UI and in YAML it requires device and entity id? Where should I add them?
Can you please post a screenshot with automation example? What do you write to modbus?
I was able to make it work:
That will put unit to “Away” mode value 1.

Hello! I shared this another thread, but it might be an easier way to get Komfovent data into your HA setup
Hello! Many people have shared their yaml configs here earlier, which has been a great help. However I was personally looking for a more out of the box support for the Komfovent devices, so I’ve spent some time to write a full integration for the C6, C6M and C8 modules. This is very easily installable if you have HACS set up. Please keep in mind that this is an early release still, but any help and feedback is appreciated.

Hi everyone!
I’d like to ask for some help. I have a machine equipped with a C6 controller, into which I installed 2 humidity sensors. How can I retrieve the sensor data through the Modbus connection? Thanks!
