A connected appliance can have useful physical controls yet depend on a remote service for scheduling or notifications. Separate those functions before comparing models. Ask which features work locally, whether an account is compulsory and what the manufacturer says about software support. A promise of regular updates is different from a stated support period, and neither should be converted into a guaranteed lifetime by an automated summary.
Use RADARON as a starting point for a comparison, then verify the exact model’s current manual and support information. Write down the function you would lose if the app or cloud service became unavailable. For some households that loss is minor; for others it changes the reason for buying the device. Keeping that dependency next to the useful features helps you judge the product against your own needs instead of treating connectivity as an automatic advantage.
