The SM301-Z is a Zigbee Wireless Motion Sensor that can be installed indoors to monitor activity. The Motion sensor uses infrared sensors to detect human movements within the sensors range and sends an alert to your phone when motion is detected. The motion sensor works in both light and darkness, but it is not pet immune. The sensor can be used on its own or in a tandem with other compatible devices. This makes it possible to create different automation scenarios in the Smart Life or Alexa and utilize available sensor’s functionalities. Recommended placement is 2-3m above the ground. Detection range is 5m with the sensor angle of 170֯.The sensor transmits motion alerts to your smartphone via Internet. The energy saving Zigbee module allows a transmitting distance of 45m from the wireless router. Low battery status can be monitored through the Smart Life app.

    I ordered one of these to see how well these sensors would work with an Amazon Echo Plus as i had heard that other makes suffer from delays in triggering an event.
    FIrstly connecting this Sensor to the Echo Plus, was really simple and straight forward.
    Once a routine was setup using the sesnor (again really easy. NB you need 2 routines, one to turn on when motion is detected and one to turn off when no movement detected for a period of time) activation of the routine is quick.
    I would rate this 10 out of 10 as a product that seamlessly links to existing Smart Home built around Amazon Echo’s.
    WOuld be great if these sensors had the options of External and Pet friendly versions.

    Was looking for a motion sensor that would connect directly to the echo plus to enable a routine to be activated without having to have another app on my phone.
    I stumbled across this wireless motion sensor and for the price i thought I’d try it.
    So pleased that I did it works perfectly, easy to connect to the echo plus and creating routines is a breeze.
    It senses quickly and routines activate virtually instantly.
    I cannot recommend this enough. It’s a great buy.
    Just need some models that are animal friendly and able to use externally, although I might get another and try and make it weather proof myself.
    For the price you cannot buy better in my opinion.

    Looking forward to trying other products in the range.

    10 out 10

    Works perfectly with Echo Plus and the sensors were each activated in under a minute. I now have an Echo Flex with the additional nightlight controlled by these sensors, to help with the nightly trips to the bathroom.

    I also have one set up to activate the porch light, which is really helpful for when the girlfriend arrives home from work (I do have this activated with Life360 and geofencing on my phone, but partner doesn’t have that on her phone, so the sensor works great for her).

    Basically, although voice control is great for a lot of things, sometimes a different method of activating functions is needed and these sensors are great for that.
