Swiss-Made Sensor – ±0.54°F Accuracy

High-precision Swiss-made sensor delivers ±0.54°F temperature accuracy and ±3% relative humidity accuracy — far more precise than typical consumer sensors.

2-Second Real-Time Updates

Temperature and humidity data refreshes every 2 seconds in the Tapo app. See live conditions in any room instantly — no waiting for slow polling intervals.

2 Years of Free Data Storage

Records and stores temperature and humidity history with visual graphs and periodic summaries. Export up to 2 years of data for free — no subscription required.

Home Automation Triggers

Automatically activates or deactivates other Tapo smart devices when temperature or humidity falls outside preset ranges. Turn on a humidifier, fan, or heater without lifting a finger.

1+ Year Battery Life

Powered by a single CR2450 battery (included) with over 1 year of continuous operation. Sub-1G wireless protocol extends battery life significantly compared to WiFi sensors.

Real-Time Push Notifications

Instant app alerts when temperature or humidity exceeds your set thresholds. Know immediately if your baby’s room gets too warm, your basement gets too humid, or your wine cellar drifts out of range.

Q: Does it require the Tapo Hub H100?

A: Yes. The T310 communicates via Sub-1G Low-Power Wireless protocol and requires the Tapo Hub H100 (sold separately) and a 2.4GHz WiFi network. The hub is what connects the sensor to the internet and the Tapo app.

Q: Why Sub-1G instead of WiFi or Zigbee?

A: Sub-1G wireless provides significantly longer battery life and wider coverage range than WiFi or Zigbee sensors. It penetrates walls more effectively, making it ideal for basements, garages, and large homes.

Q: How many sensors can one hub support?

A: The Tapo Hub H100 supports multiple Tapo sensors simultaneously. You can place T310 sensors in different rooms and monitor all of them from a single app dashboard.

Q: Can it trigger non-Tapo smart devices?

A: The T310 natively triggers other Tapo smart devices. For broader smart home integration, it works within the Tapo ecosystem which connects to Alexa and Google Home for expanded automation possibilities.

Q: Is the data storage really free?

A: Yes. TP-Link provides 2 years of temperature and humidity data storage and export at no cost, with no subscription required. Data is accessible and exportable directly from the Tapo app.

Q: Where are the best places to put it?

A: Baby’s room, bedroom, basement, wine cellar, greenhouse, server room, garage, or any space where temperature and humidity matter. Avoid placing directly in sunlight or near heat sources for accurate readings.

⭐⭐⭐⭐⭐ — Emily R.

"I have 4 of these throughout my house. The accuracy is noticeably better than cheaper sensors I’ve tried. The automation feature turns on my humidifier automatically when the bedroom drops below 40% RH. Set it and forget it."

⭐⭐⭐⭐⭐ — James W.

"The battery life is incredible — still going strong after 14 months on the original battery. The Sub-1G signal reaches my detached garage with no issues. The 2-year data history is genuinely useful for spotting seasonal patterns."

⭐⭐⭐⭐⭐ — Sophia K.

"Perfect for my baby’s nursery. I get an instant notification if the room gets too warm at night. The Swiss sensor accuracy gives me confidence the readings are actually correct, not just approximate."
