Description

This purchase includes 3x Tapo T110 Contact Sensors and 1x Tapo H100 Smart Hub with Chime. Tapo enhances home security and convenience through its ecosystem of smart devices managed by the central Tapo Hub. Contact sensors placed on doors and windows allow users to remotely check their status via the Tapo app, eliminating uncertainty. The Hub utilizes an ultra-low power protocol, extending the battery life of connected sensors, switches, and buttons up to tenfold. For integrated security, opening a door or window can trigger paired Tapo pan/tilt cameras to track movement and sound an alarm on the Hub, while real-time app notifications and an activity log provide immediate awareness and review capabilities. Furthermore, these sensors can be paired with smart lighting for automated illumination in designated areas. Installation is effortless with magnetic and adhesive mounting options, and the sensors' compact size ensures discreet placement throughout the home. Each Tapo contact sensor is measured as 2.42 x 1.48 x 0.48 inches. The Tapo Smart Hub is measured as 2.8 x 2.5 x 2 inches.

Reliable, Fast, and Easy to Use — A Great Starter Kit for Smart Home Security
Style: Contact Sensor + Hub Size: 3-Pack
I picked up the Tapo Door Sensor Starter Kit to add some simple automation and security to my home, and it has exceeded my expectations. For the price, you get a surprisingly polished setup that’s easy to install, Matter‑compatible, and extremely reliable. Quick Setup and Rock‑Solid Connection The included Tapo Smart Hub pairs with the sensors in seconds. The hub’s built‑in chime is a great touch — no need to buy anything extra just to get audible alerts. Once everything is connected, the sensors respond instantly. No lag, no missed events. Accurate, Real‑Time Notifications The 3 included contact sensors are small, lightweight, and very accurate. Whether it’s a door, window, cabinet, or even a garage entry, the notifications hit my phone immediately. The app lets you customize alerts, schedules, and automations without any hassle. Matter Compatibility = Future‑Proof One of the biggest selling points is that the kit is Matter‑compatible, which means it plays nicely with multiple smart home ecosystems. It’s great knowing I’m not locked into one platform. Smart Automations That Actually Work I’ve set up automations like: Turning on lights when a door opens Sending alerts if a window opens at night Triggering routines when I leave the house Everything runs smoothly and consistently. Built‑In Chime Is Surprisingly Useful The hub’s chime is loud enough to hear across the house and can be customized for different sensors. It’s perfect for knowing when kids open a door or when a package arrives. What I Love Most Fast, reliable detection Easy setup with clear instructions Matter support for cross‑platform compatibility Built‑in hub chime Compact, low‑profile sensors Great value for a 3‑sensor starter kit What Could Be Better The sensors use adhesive, so repositioning requires new tape Would love a battery percentage indicator instead of just “low battery” alerts Bottom Line If you want an affordable, reliable, and future‑proof way to monitor doors and windows, the Tapo T31 Starter Kit is a fantastic choice. It’s easy to set up, works flawlessly, and integrates beautifully with smart home automations. Highly recommended. ... show more

Tapo For The W
Style: Contact Sensor + Hub Size: 3-Pack
Switched to Tapo after the company I was using decided to just have their app go offline entirely and get removed from app store. Tapo is a way better product, is way more versatile as I can use Kasa products too utilizing the same app, and these doing everything I need them to do, and they offer an actual alarm hub which believe it or not, is harder to find than you'd think. Would love to see TP-Link put out an alarm keypad to arm and disarm my setup automation, but even without it, this system has everything i need covered, unlike all the other options ive tried previously. Im really surprised these are not talked about more and that they're not leading the charge in DIY smart home security. Needless to say, im switching everything over...Light switches, door sensors, outlets, bulbs, etc and ALL, so far, have been a VAST improvement over the previous brand I relied on. Now, this product in particular has a decently loud alarm, although I wouldn't say its 1 for your whole house loud, I already have 2 and will likely add 1 more to cover 1st floor, 2nd floor, and garage. Will have to update later on battery life but install was super easy, none of the adhesives have failed yet, again like my last ones did (fell off in first week), they were very simple and easy and quick to connect to app and get setup, and have not gone offline or lost connectivity yet. Best part, the pricing seems very reasonable to me, especially from Amazon. ... show more

Great Door and Window Alarm System at an Affordable Price
Style: Contact Sensor + Hub Size: 3-Pack
This alarm system works great and is very affordable! I use the sensors on my doors and even on my refrigerator, since I sometimes forget to close it completely. Each sensor can be configured for different situations, which makes the system very convenient and flexible. The wireless range is also excellent. I placed the hub in my living room, and it communicates perfectly with the sensor in the garage. ... show more

Great for Garage Doors!
Style: Contact Sensor + Hub Size: 3-Pack
I got these to use in place of a reed switch for my garage doors. I was having trouble finding decently rated reed switches on amazon, reports of melting and incorrectly operating switches glore. Yikes! These work great for this application, and in retrospect, not having to run a wire to a reed switch resulted in a much easier overall installation. Just watch your sensor placement to avoid your doors track. I paired these with some Shelly 1 minis to operate the garage door opener. If you don't want to mess with electrical wiring to the Shelly, get the Shelly 1 plus version, and you can wire it to a standard 12v DC power cord, and use an normal outlet instead. You'll have to replace the batteries in these sensors every few years, but that's easy and cheap enough to do once in a while. They seem durable, I dropped one from 7 feet up onto concrete, and it still works just fine. I set these up in the Tapo app, and then added them to Home Assistant. The tp-link integration works great with the hub and t110 sensors, and they can be used locally without requiring the Tapo app. The sensors sensors seem much more responsive via Home Assistant vs the Tapo app. The only downside is the price, the t110 sensors sell for $20 a piece, but given the quality of reed switches on amazon, I'd rather spend a bit more, and not risk a fire. I purchased another set to install on my entry doors, and will probably put some on my fridge doors eventually as well. If they were cheaper, I'd put them on all my windows too... ... show more
