As someone who has played around with home automation and done some homebrew IoT, my biggest concern to be honest is that the extra functionality will make common appliances more difficult to maintain than they already are.
Yeah, exactly. I really don't want an internet-connected IoT refrigerator, but I wouldn't mind one with some standardized interface that allows it to be optionally augmented with IoT functionality of my choosing.
That interface shouldn't be much more complicated that some connectors and passive wiring. Then I could connect a communications and sensor modules and replace them independently as needed.
Right, maintaining a dozen sensors and integrations with other appliances is a pain in the ass. Also, I have no interest in moving the controls of the device from the appliance to my smartphone. 95% of the time it's more work to pull out my phone and launch an app than to flick a physical light switch.
