AttributeError: 'EcoVentFan' object has no attribute '_unit_type'

I'm getting the below error with ver 1.3. The fan entity is created but unavailable.

This is my config

fan:
  - platform: ecovent
    name: Master Bedroom dMVHR 
    ip_address: " 192.168.0.22" 
    device_id: "002E002642435713"

Similiar error. I think I have a v1 TwinFresh fan, maybe it's not supported? What kind of fan do you have @euinor ?

[euinor]

It is a Blauberg VENTO EXPERT A50-1 S10 W V.2. The A50 is not explicitly supported but it should be the same as the supported Blauberg fans. I do have an A30 and an A30 DUO so maybe I'll try those.

What version of HA are you using?

[euinor]

This is with 2023.1.0

[yarosman]

Have same issues with A100 on 2023.3.5

[kondrikserg]

And i have similar error with _unit_type

[archipita]

I am trying to use this extension as well and I have the same error with unite_type.
Commenting out this line in fan.py, I get the error on the next parameter (airflow).
The first two are working (airflows and id).
Can it be that there are changes with the parameters' names?
My HA is 2023.11.6 and the integration is v1.3.
