Modbus Sensor TCP for Komfovent

Could you share your config where I can see how you triggered max air ( changing value) ? Or you just set boost mode? :slight_smile:

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 can’t understand how to set maximum value for the vent. Maybe someone will help us :slight_smile:

Cool. For the max value: can’t you use some network sniffer to check how the app communicates with the main unit?

I don’t know if it helps, but I requested modbus protocol from Komfovent:

Hi, did some design, added some buttons and moved some.
Works like charm.

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.
configuration.yaml

Sorry for my estonian translations, you can edit it at lovelace.

I’m estonian as well, so all good. Thanks

HI,

How you solved problems with state colors? without colors it is not clear which status

You need to install button-card.

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 availble…
Is this a case of “new style” modbus configs ? Are somon already have new and can share :slight_smile:

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 it’s 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 don’t 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 it’s 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:

Ok ,thanks for th new code .
There is on thing with that , it is not changing th state , whn i change it from controller or via web page. ( So when i turn on Auto in HA it will be always on , even when i turn of from controller)… Posible to fix it ?

I uptaded all code
