How should it be related to sanctions, ie what specific sanctions? If Apple keeps working and taking payments on App Store (even Apple TV+), HomeKit is working, etc. there’s no reason that Netatmo should not. This was out of the blue. No warning, or statement. They even kept selling the devices for some time on official Russian website.
