Ken recently automated his home with Google Nest, but the problem he's having is that when he's asking his phone to take a picture, he's told by Google Nest that they can't do that. Leo says that's a common issue as sometimes, Google doesn't know where to process a request. That goes away over time as Nest learns speech patterns. It also helps to be more specific in commands.
The screen on Gary's exercise bike doesn't turn off unless he unplugs it, so he got a smart Wi-Fi enabled plug that he can use through Alexa. He's wondering if that could harm it in some way. Leo says it's the same as if he were just unplugging the bike and plugging it back in, so there shouldn't be any harm in that. The only exception is if it somehow sends a power spike to it when it turns back on, but it should be OK.
