Netatmo Rain/Wind Sensors via HomeKit: Useless?

Hi,
is it true that Netatmo Weather devices (rain and wind) are useless when you try to connect them via Homekit? Is it again that Homekit is simply not supporting the measurements (wind speed/direction and amount of rain) and hence they are not visible in HomeAssistant?
I’m still looking for a local integration of Netatmo because the cloud is not really reliable and I want to have automations like my controlling my awning when wind gets to high or it starts to rain… I need a reliable near-realtime integration with HA for that…
THANKS
