cannot import name 'ATTR_STATE_CLASS'

[magicpapy]

Hi,

First of all, thanks for this work, and for the documentation, which is crystal clear.

I have an issue while trying to restart after having installed as described here : https://github.com/ssenart/home-assistant-gazpar

Here is the error message :
Platform error sensor.gazpar - cannot import name 'ATTR_STATE_CLASS' from 'homeassistant.components.sensor.const' (/usr/src/homeassistant/homeassistant/components/sensor/const.py)
And of course I can not find the gazpar sensor (even if I find a device).

My password includes no special characters (it includes a "-" mais it is not a special character ?).
I looked at utils.py, which imports ATTR_STATE_CLASS, and if I just remove ATTR_STATE_CLASS, I have the same problem with SensorStateClass.

I use a docker installation of HA.

I'm quite lost, so a help would be nice :)

Hello,

It looks like an incompatibility with HA version. Which HA version do you use and same question on version of home-assistant-gazpar ?
