Let me start by saying this little floating gadget has saved me SO many trips outside to check my hot tub temp—I can now lazily ask Alexa while binge-watching Netflix. The LoRa connection is legit; my hub’s indoors, and the thermometer floats happily 50ft away in the yard with zero dropouts (take that, WiFi-dependent devices!).

The app alerts are clutch. When my spa hit 104°F last week (oops, forgot to turn it down), my phone buzzed instantly. Also obsessed with the battery life—5 years?! I’ve had mine since winter and it’s still at 100%. Though heads up: like others mentioned, mine DID get condensation inside after 2 months. YoLink sent a replacement ASAP with DIY sealing instructions (pro tip: silicone grease is your new best friend).

Minor gripes? The display gets foggy when wet (ironic for a pool device), and resetting requires button presses underwater—not ideal with pruny fingers. But for $40? Worth it just to impress guests by shouting ‘Alexa, is my margarita-ready pool temp yet?’ from the couch.
