Danfoss Air configuration

Configuration
1

I’m not sure whether I have a configuration problem, but I can’t get the Danfoss_Air integration to work with my Danfoss Air W2 and Danfoss Link CC.

If I use the followin configuration, I get 10 Danfoss sensors like air exhaust fan speed, air humidity and so on, but they all have an unknown state.
I also get tree switches, air bypass, air automatic bypass and air boost, but they all return an error.
“Update of switch.danfoss_air_boost is taking over 10 seconds”
“Update for switch.danfoss_air_boost fails”
In the log I get a “Connection refused”

danfoss_air:
  host: 192.168.1.189

I have tried using ’ and " around the IP address.

My Home Assistant version 0.104.3 and running in Docker.
I can see all the readings from the Danfoss HRV PC-Tool.

The problem was that I used the wrong IP address.

Hi Kasper,

I have also just added my Air unit to HA - and would like to see if I can add more functionality to the component.

Do you have a link to where you downloaded the PC-Tool - it seems Danfoss has decided to remove it from their website…?

Kind regards,
Kasper.

Thanks!

From another thread I found, I learned that there is also a more advanced version - link below.

Hi Kalk.

Having the same issue. My log is full with errors, did you find any way to correct this?

Im having the right IP, because i can set and static ip for the unit (W2) and have done that.
