Hi,
I was thinking about getting a Netatmo NWS01 and integrate it into my HA setup.
Is it possible to use it purely local without Internet connectivity?
Looking at how this thing is set up in HA, I assume that it can only be used as a paperweight without the vendor’s cloud service, right?
That would be a deal-breaker for me.
I am not 100% sure but I think the Netatmo weather station does support homekit which should provide a local interface to your device. I haven’t tested it but it might be worth a try.
