Tapo Door Sensor Starter KIT, Matter Compatible, 3X Smart Door Window Contact Sensor and 1x Smart Hub with Built-in Chime, Smart Automation, Real-Time Notification, T31 KIT

Great for Garage Doors!
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…

Pretty neat system with a couple of flaws
These devices are pretty small and will be fairly unobtrusive if you still install them on a white door her window frame. They seem to work very reliably and the table app offers several options for notifications.The mounting adhesive blocks provided are really thick and cause the devices to protrude from the surface, which detracts from the appearance.Although Amazon Alexa can detect whether these devices are opened or closed, it can’t create a routine that will check their status and produce an announcement if one or more are open. It also can’t use the information in a hunch. So you can ask Alexa if one or more devices are open but you can’t use it to automatically tell you if something is open at a time when it should not be. The Tapo app is also not able to do this, although it can trigger a check of status based on an event from a motion sensor.When I was installing them, at least with the first batch, I found that if I pulled the tape out too early that the LED would stop blinking and then I had to take the sensor apart to hit the reset pin inside of it in order to start the pairing process. So it is best to wait until right before you are ready to pair the device to take the blue tape out that keeps the battery from engaging.

TAPO is the WAY TO GO! Automate your Life like you’re Rich, but quietly on a Budget.
Tapo has quickly become one of my more favorite smart home brands with their wide range of feature-filled gadgets for affordable pricing. Everything is easy to use and I’ve had very little issues with their reliability. These door sensors follow that trend! I open a door, the light switch goes on within a second or occasionally two. Provided, these do require a hub but that takes a load off your router, so it’s preferred! The battery life has been so good, that even when the app claims a battery is getting low, I continued to use the sensor for over a month or two without interruption.I am a bit sketchy with their security, or potential lacking of, considering Tapo descended from Kasa which both are owned ty the questionable Chinese-owned company, TP-Link. I’ve heard of instances where these communicate with Chinese IP Addresses. Who knows what information they send back. That’s a risk with many things in today’s technology… The best way to set these up is to have them on their very own network, isolated from everything but their main API. I’ve used the Kasa/Tapo brand for the past 3 years and I’ve never had any issues!

Excelente producto, configuración súper rápida, bastante recomendables, funcionan perfecto en Apple Home, definitivamente compraré más, y probaré otros dispositivos de la marca.

Installed on my front and rear house doors to know when they are open, or to know if they are left open at any time. Paired with my Tapo smart hub, I was able to install these in 5 minutes. It was so simple.I created an automation so that if a door sensor goes off in the night, my Tapo smart hub sounds an alarm. It’s a great theft deterrent and works every time.These are the ones. Tapo is amazing. Get it!
