Fantastic motion sensors
I bought two of these motion sensors at the beginning of January. Both are located outside, though protected from the elements. One is on my front porch, underneath an eave, directed at the door. The other is inside my mailbox at the street. The mailbox is all metal; the motion sensor is mounted at the back of the box, held in place by the magnet on the device; very easy installation, just snaps in place without any mounting bracket. When the mailbox is opened, the sensor detects motion and sends an alert to my Smartthings hub, forwarding it to an Amazon Alexa routine to let me know that the mailbox is being accessed (with both an Alexa voice and a smartphone message); the mail has been delivered.The sensor on the porch is about 15 feet away from a Smartthings ZigBee repeater located in the garage. The mailbox sensor is about 50 feet from the same repeater. Both motion sensors have operated almost flawlessly since I installed them seven months ago. Once I thought I had a problem with the mailbox sensor because I kept getting repeating alerts. Turned out that the mail deliverer had not closed the door on the box, and every passing car was triggering an alert. Only happened once in seven months.I had my doubts when I installed these indoor units outside (and in a metal mailbox). I didn't know how they would operate under extreme weather conditions. During winter the temperature was well below zero on several nights. And now during summer the temperature inside my mailbox often reaches well beyond 120 degrees for hours on end. I know this because the motion sensors have built-in temperature sensors as well, and report every one degree change back to Smartthings, recording it in the log. The log is filled with entries every day. In addition, battery life is amazing. The batteries in both of the sensors are at 83% remaining life after seven months of weather extremes.These motion sensors have surpassed my expectations! I am very impressed.

4.0 out of 5 stars Works well with Alexa
Reviewed in the United States on January 19, 2019
I initially connected this to my Samsung Smartthings hub, but was unhappy with getting alerts through my phone. I then used a paper clip to reset and instead connected to my Amazon Echo (Alexa) hub. From there, I easily set up a routine to alert me through Alexa when motion is detected. You can make your own custom message. It’s fantastic and I am ordering more. I like moving mine around depending on the motion I’m wanting to detect, so I have not yet affixed it to anything. My hub is connected to 2.4 ghz. Right now, it’s on the stairs alerting me to traffic in or out of my foyer.

Mucho mejor y más funcional que la primera generación

Trae una base magnética con un pegamento 3M que una vez pegado en la pared es bastante difícil de quitar así que asegúrate bien de que ahí quieres el sensor

La base te permite mover el sensor a libertad así que lo puedes poder incluso en los ángulos más raros que imagines

Nada se le escapa, el sensor tiene muy buena sensibilidad y sin punto ciego, puedes pasar abajo del sensor y si te detecta, a diferencia de otras marcas que ya he usado

Las baterías que usa son económicas $60 y te duran unos 6 meses (dependiendo de cuánto movimiento tengas en la zona)
