Frequently Asked Questions
Do I need a Tapo Hub to use the T315?
Yes. A Tapo Hub (such as the Tapo H100 or H200) is required to enable smart features including remote monitoring via the app, home automation triggers, push notifications, and cloud data logging. Without a hub, the T315 will still display readings locally on its E-ink screen, but smart functionality will not be available.
How accurate is the temperature and humidity sensor?
The T315 uses a Swiss-made sensor with a typical accuracy of ±0.3°C (±0.54°F) for temperature and ±3% RH for humidity. Readings are updated every 2 seconds, making it one of the more accurate consumer-grade environmental monitors available.
Can the T315 automatically control my air conditioner or heater?
Yes, via Tapo automations. If your air conditioner, heater, or fan is connected to a compatible Tapo smart plug or smart switch, you can create rules in the Tapo app to automatically turn those devices on or off based on the T315’s temperature or humidity readings.
How long does the battery last?
The T315 runs on 2× AAA batteries with a rated battery life of up to 2 years under normal usage conditions. Battery status is displayed on the E-ink screen so you always know when a replacement is needed.
Can I export my historical data?
Yes. The Tapo app stores up to 2 years of temperature and humidity history in the cloud at no cost. You can export this data as a CSV file sent directly to your email address for analysis or record-keeping.
How do I mount the T315?
The T315 supports three placement options: freestanding on a desk or shelf using the built-in stand, wall mounting using the included adhesive strip, or attachment to any metallic surface using the magnetic base. No tools or drilling are required for any of these methods.
