The Tapo T315 is a sleek and functional smart temperature and humidity sensor with a paper-like 2.7-inch e-ink display, designed to bring both visibility and automation to your living spaces. The screen shows the current temperature, humidity, battery status, comfort “emoticon” feedback (happy, neutral, or uncomfortable), and signal strength, readable at a glance and easy on the eyes—even from across the room with minimal glare.

Built around a Swiss-made sensor chip, the T315 delivers accurate, real-time updates every two seconds, with ±0.3 °C / ±0.54 °F temperature accuracy and ±3% relative humidity accuracy. TapoTP-Link Its operating range spans –20 °C to 60 °C and 0% to 99% RH, making it suitable for a wide range of indoor environments. TP-Link+1
Thanks to its e-ink display and low-power Sub-1 GHz wireless connection (via a Tapo Hub), the T315 achieves an impressive battery life of up to 2 years on two AAA or LR03 batteries. TP-LinkCity CenterFG Tech Store
Smart Features & Automation
-
Instant Alerts and Comfort Zones: You can set your preferred temperature/humidity ranges in the Tapo app, and if the sensor detects values outside those ranges, it triggers a push notification or smart home automation. TapoCity Center
-
2-Year Cloud Logging & Export: T315 stores up to two years of historical temperature and humidity data in the cloud. You can view graphs or export the data as CSV for analysis, helping you track trends and optimize comfort or climate control. TapoB&H Photo VideoCity Center
-
Smart Home Integration: When paired with a Tapo Hub H100/H200, the T315 becomes a powerful trigger point for home automation. For example:
-
Turn on a heater when the temperature drops below 16 °C
-
Activate a fan or air conditioner when humidity or heat gets too high
-
Automatically run a humidifier if humidity falls below your comfort threshold
-
Log temperature/humidity data even when you’re away from home and visualize trends remotely
Automation lets you maintain comfort and save energy with minimal effort. TapoTP-LinkCity Center

-
Comfort Feedback at a Glance: The e-ink display shows an emoticon face reflecting your room’s comfort level (“smiling” for good conditions, “neutral”, or “frowning” when temps/humidity are outside your personal comfort zone). This gives you instant visual feedback without opening an app. TapoTP-Link
Flexible Installation
The Tapo T315 is easy to place or mount: sit it on a table or shelf, mount it on a wall using the included adhesive tape, or attach it to a metallic surface if convenient. Its compact size and low-profile design help it blend into bedrooms, living areas, plant rooms, wine cellars—or anywhere monitoring or automation might help improve comfort. TP-LinkB&H Photo Video
