Tapo T315 Smart Room Thermometer & Hygrometer
The T315 brings Tapo's smart home ecosystem to basic room monitoring, pairing a 2.7 inch E-Ink display with app notifications, historical graphs and voice control support. It sits a step up from a simple digital hygrometer, at the cost of needing a hub to unlock its smart features.
Key features
- Real-time temperature and humidity readings, accurate to ±0.54°F and ±3% RH
- 2.7 inch E-Ink display showing temperature, humidity, comfort level, battery and signal status
- Free data storage for 2 years, with visual graphs and periodic summaries in the Tapo app
- Automation rules to trigger other smart home devices when readings fall outside a set range
- Voice control via Amazon Alexa or Google Assistant once linked to a hub
- Desk-standing or wall-mounted, alkaline battery powered
The hub requirement
This is the detail to check before buying: the T315 needs a Tapo H100 or H200 hub, sold separately, to enable app notifications, remote monitoring, data logging and automation. Without a hub it still shows temperature and humidity on its own E-Ink screen, but none of the smart features work. If you already run a Tapo hub for smart plugs or cameras, this slots straight in; if not, budget for the hub alongside it.
How it compares to a basic digital hygrometer
Against a simple unit like the ThermoPro TP49 or the ETI Healthy Living thermometer and hygrometer, the T315 costs more and needs extra hardware to reach its full potential. What that buys you is remote monitoring, app alerts if a room gets too damp or too dry, and automation triggers, useful for a nursery, greenhouse or anywhere you want a warning rather than having to walk over and check a dial.
Who it suits
Households already on the Tapo smart home platform, or anyone wanting app alerts and a data history for a specific room rather than a glance-and-forget reading. For a straightforward reading with no app or hub involved, a standard digital hygrometer remains the simpler buy.
