A sealed wireless thermometer that sits inside your aquarium — the temperature probe stays submerged while the electronics and battery remain above the waterline. Attaches with a suction cup, just like a traditional aquarium thermometer. Readings appear live on the AquaHub display, and the Smart Heater relay uses them to maintain your target temperature automatically. The CR2032 battery lasts over 3 years. When it eventually dies, just replace the unit. No cables, no charging, no hassle.
