Shelly Plus H&T

Battery life is the big win here—charged it once back in February and it's still reporting accurately every single day. The Wi-Fi connection has been rock solid too, no dropouts even through two walls.

Battery life is the big win here — I haven’t touched it since I mounted it in the living room three months ago, and the readings stay dead accurate. The Wi-Fi link has been rock solid too, no drops or lag on the app.

Set it up in the kitchen to keep an eye on humidity while cooking, and the readings update fast enough to see changes almost in real time. Charging once a year is honestly a relief compared to the old sensor I was swapping batteries on every month.
