I don't touch 90% of WiFi smart devices unless they are Tuya controlled and even then I'm iffy. I vastly prefer z-wave/zigbee because if SmartThings goes belly up I can switch to Wink or any other compatible hub fairly easily. And while my Alexa devices are probably where I am "weakest" I have a lot of stuff running through HomeBridge and if I needed to I could move to HomeAssistant if I needed/wanted to.
