Samsung SmartThings Motion Sensor: Add this sensor to your SmartThings hub to trigger functions when motion is detected. The unit senses motion up to 15' with a 120° view angle, then sends an alert to your compatible Apple® iOS, Android or Windows mobile device.
Q: this sensor connects to the hub and will the hub connect to my att hotspot?
A: Hub is not wireless and therefore needs router to connect to internet. Also it needs constantly Internet connection.
Q: does the motion sensor work through a glass window
A: No it is infrared so it does not work through a window. If you want an outside motion sensor that is compatible with SMart Things hub look at the Ecolink motion sensor and it works great if you put it under the eave a house.
A: buy at best buy. cost is between 40 and 50 dollars each. the hub sill take care of alerting your cell phone when setup to do so
A: Yes it is battery operated and it will fit in a mailbox. I am not sure about the humidity but it is probably not water resistant.I think you should consider a door sensor that is a simple open or close switch. When the door opens your system would know the same for when it closes. I know with my Smartthings I cold get it to send me a text when the mail box opens. The door sensor should also be cheaper. I have several door sensors that have been in place for well over a year that still show 100% battery level a motion detector that I put in at the same time is at 70%. You can do the same thing with the motion detector but I would consider the door sensor that is assuming that the mail person closes the door all the way.
Q: Do i need to buy a hub, or can it operate with an app through a phone?
A: You'll need the hub as well.
A: You could use the sensor like that if it's connected to the hub and you used IFTTT or Stringify in combination with a Z-WAVE siren, or you could have a notification sent to your phone using IFTTT, even call your phone!
A: No. It is not waterproof. Would need it protected from elements.
