I completely agree with the grandparent. This is all avoided by using Zigbee or Z-Wave devices. All our smart lights are Hue. If they decide to stop supporting it, they can be controlled with the Samsung/Aeotec SmartThings Hub, Home Assistant, Zigbee2MQTT, or whatever you please. Similarly, our smart plugs are also Zigbee and we use a couple of Aeotec Z-Wave temperature/humidity sensors.
Best of all, less worries about yet another IoT device with probably vulnerable software that we have to put on a VLAN/IoT WiFi network. Zigbee and Z-Wave are also much simpler than WiFi/Bluetooth, so less likely that they are a swiss cheese of vulnerabilities.
