I agree on the coffee machine. On the thermostat, not so much. We keep pretty irregular hours so being able to control the thermostat remotely, so the house isn’t being heated unnecessarily but is warm on our return, is useful.

Yours may not, but that's just your personal preference. A lot of folks enjoy these products. An argument could be made that no one needs a coffee machine or thermostat to begin with.
