I hung it by the front door and the e-ink display is so crisp I can read the temp from across the room. It's been two months and the charge hasn't budged, so I'm genuinely curious to see if it really does last a year.

Battery life is the real winner here—I’ve had it mounted in the hallway for months and it’s still showing the same charge level. The e-ink screen updates crisply even in low light, and setting it up on Wi-Fi took under five minutes. For a set-and-forget sensor, this thing nails it.

Honestly, the battery life is the real selling point for me—I set it up in the garage and completely forgot about it until I remembered it's been over a year on that single charge. The e-ink screen stays crisp and readable even in that dim light, which is a nice bonus.
