Netatmo CO2 Sensor via Vera Integration not showing in HA

Hi,
I am using the Vera Integration, and all my sensors are visible in Home Assistant.
In my Vera I use the Netatmo integration, and those sensors are imported also.
Most of them work fine, but the CO2 sensor and the Sound sensor do not show a value.

I made sure that the units of measurement are in ppm, but nothing goes.
In Vera the value shows just fine.

Any ideas?
