When it comes to building your smart home, the best security cameras, best smart locks, and best video doorbells are often the first devices people think about. However, there's another gadget that's overlooked, but can bring your smart home to the next level. Even better: It's cheap.
Earlier this year, I decked out my townhouse with a handful of motion sensors. I went with the Aqara P1 ($25, Amazon) sensor because it's affordable, has a battery life that lasts up to five years, and is easy to use since it plays nicely with both my Homekit and Alexa smart home platforms. This little guy accurately detects 360 degrees of activity to kick off automations within my smart home.
