Tapo T110 Contact Sensor for Doors and Windows

Tapo T110 is a contact sensor for monitoring doors, windows, cabinets, and other items that open or close. It requires a Tapo Hub H100, sold separately, and a secured 2.4 GHz Wi-Fi network for hub connectivity. The sensor communicates with the hub using a Sub-1G low-power wireless protocol.

At a glance

Phone alerts are claimed when an opening is detected, and the sensor can serve as a trigger for Tapo Smart Actions.
The listing claims up to two years from one CR2032 battery when triggered fewer than 30 times per day.
The stated 15 mm sensor-to-magnet gap may accommodate fixtures with wider gaps, subject to fit at the intended location.

Pros and cons

Pros

Adhesive mounting is described as tool-less, and the stated 15 mm gap supports a range of door and window setups.
Smart Actions can use sensor state to trigger actions such as turning Tapo lights on or off.
The listing includes a CR2032 battery and adhesive for installation.

Cons

A Tapo Hub H100 and a secured 2.4 GHz Wi-Fi network are required, so this is not a standalone sensor.

What to know before buying

The claimed battery life of up to two years assumes fewer than 30 triggers per day. The listing also notes that Sub-1G frequency bands vary by region, so confirm the sensor and hub use compatible regional bands. Hub features such as its siren and support for up to 64 sensors belong to the separately sold H100, not this sensor.

Customer feedback highlights easy installation and setup, reported compatibility with the Tapo Hub and app, and useful alerts and automation. Some customers also mention the wider gap tolerance, which may matter on older doors. Battery feedback is mixed, with reports of long life as well as dead batteries. These are customer impressions, while the listing’s up-to-two-year estimate is conditional on fewer than 30 triggers per day. Aggregate ratings lean strongly positive overall, but do not establish how the sensor will perform in a particular setup.
