TP-Link Tapo Motion Sensor, Requires Tapo Hub, Long Battery Life w/Sub-1G Low-Power Wireless Protocol, Wide Range Detection, Adjustable Sensitivity, Real-Time Notification, Smart Action, Tapo T100

I was surprised how small this was, about 2x3 inches... Not a dig, it works perfectly. We have some sensors more than 50' away, and it works great. Easy to set up, only one required per wifi environment.

Got this to go with a door sensor and camera. Setup was quick and easy. Good instructions. Sound is loud enough for the alarms we set up.

Tapo devices are solid. Hub works for contact sensors and water leak detectors.

Used Tapo phone app to setup the hub and to connect to a Tapo Temperature and Humidity sensor. We have the sensor in our bedroom and initially also put the hub in the bedroom. It is too bright for that. The LED is bright enough to bother us at night.I have used other IOT phone apps. I am familiar with these types of apps. The Tapo phone app is good and easy to use.

My garage light (different from the garage door opener light) is controlled by a Kasa motion sensing switch. Unfortunately due to the switch location, the coverage is very poor so the light often turns out even when we’re moving around in the garage.Added 2 of these and a Tapo hub - both adding to the Tapo/Kasa app as smart control trigger for the Kasa motion sensing switch and it solved all the problem. One points to my work area and another near the garage door for convenience when we have the door open and we are right outside.

This hub does not work with the Tapo Door Bell. You cannot pair it or set any smart actions if someone presses the doorbell. I was hoping to use it as a second and third chime for a moderately large home. But only works with sensors and other items.Its a bit expensive though to just be a hub and being limited to some items is not so great.Does get pretty loud but the alarm choices are not so great either.Solidly built and has survived being removed from the socket by my dogs.No battery required as it plugs into the power outlet.Just disappointed it cant be used with the door bell.

The Tapo sub-1GHz iot system is great - great utility and great value. I now have several environmental sensors, buttons, water leak detectors and motion sensors through our two storey home and they work great. Beware that things like large metal objects (our external doors) and Bluetooth and Wi-Fi interference can still affect systems like this, so be careful with your placement. However, it's so cheap to just buy another hub to solve any persistent connectivity issues that it's really not a big deal. Also, Wi-Fi, even with a great mesh system, is less reliable than sub-1GHz.My bottom line? This is a great system to invest in. Plus, it complements Tapo's other (Wi-Fi) smart devices.

Small but works, 3 car garage and use it on the far end linked to my kasa motion sensor switch.Just wished it didn't have to have a hub.
