IoT nightmare
/ˌaɪ oʊ ˈtiː ˈnaɪtmɛr/
UncommonWhen your smart home devices fail, conflict, or get hacked in a way that makes you regret buying them.
Usually used in frustration or retrospectively as dark humor. People who have lived through a bad smart home failure often become the most vocal critics of IoT complexity.

- The dependencies required to run basic home functions become absurd.
Do not use it when
- One device has a minor bug or connectivity hiccup.
