device_class cover IKEA not defined

[chpego]

Hi !
I have 4 Zigbee devices from IKEA of the "cover" type, unfortunately the "device_class" doesn't seem to be defined on Home Assistant. Is it normal for this info not to be set via MQTT or HA automatically?

I've had a problem with HA and Assist not being able to execute my voice commands because the device_class isn't defined.

the domain is well defined but not the device_class

For example, with an another device cover (indépendant de Z2M), the device_class is defined :

I've already try to re appair the device

for now, and if anyone hasn't got a better answer, I've added a customization via the configuration.yaml file as follows:

after a Z2M restart, the device_class field is automatically filled in HA
