What's the most useless smart home gadget you've ever bought?

I'll start. A 'smart' plant pot that sends a notification when the plant needs water. I already knew the plant needed water. The plant was visibly dying. The notification just made me feel judged.

To be fair, it did work. I just didn't need it to. What's yours? Bonus points if it's still in a drawer somewhere.
