Tapo T315 Smart Thermometer and Hygrometer

The Tapo T315 is a smart indoor thermometer and hygrometer for displaying temperature and humidity and connecting readings to the Tapo app. Its smart features require a separately sold Tapo H100 or H200 hub, so it is best suited to buyers already using, or planning to add, compatible Tapo equipment.

What to know before buying

  • The stated battery life of up to two years is a laboratory estimate with actual results subject to variation.
  • Alexa voice control is stated to cover temperature only. The listing says the T315 does not work with SmartThings.

Listing details to confirm

The listing gives conflicting screen descriptions: it calls the display LCD in one detail and a 2.7-inch e-ink display elsewhere. It also gives temperature accuracy as ±0.54 ºF in the feature text but separately lists ±0.3°C, and humidity accuracy as ±3% RH. Confirm the display and measurement accuracy details if they are important to your purchase. Smart features require a compatible Tapo H100 or H200 hub, and the listing warns that regional Sub-1G frequency bands must match between device and hub.
