One of many reasons I prefer home automation hardware that uses ZigBee, Z-Wave, or Thread over using WiFi. If it uses WiFi it almost always wants to connect to or worse requires a cloud, where the dedicated home automation network tech is basically the polar opposite and requires that it work entire directly locally or with a local hub.

Other major reason being that "IoT" devices usually have the shittiest WiFi radios that usually don't even support 5 GHz and almost never support WiFi 6/7 modes where they aren't wasting a ton of airtime on their low-bandwidth communication.
