This plugin slows down Homebridge

[koupus]

Hello,

First thanks for your work.

I've this in the homebridge logs :
[homebridge-withings-air-quality] This plugin slows down Homebridge. The read handler for the characteristic 'Carbon Dioxide Level' didn't respond at all!. Please check that you properly call the callback! See https://git.io/JtMGR for more info.

and:
[homebridge-withings-air-quality] This plugin generated a warning from the characteristic 'Carbon Dioxide Level': Characteristic not in required or optional characteristic section for service AirQualitySensor. Adding anyway.. See https://git.io/JtMGR for more info.
