Features

  • [Motion Sensor Detects Your Movements] With a motion detection range of up to almost 30 feet within 110 horizontally and 55 vertically, theres more than enough range to secure an entire room of your home. Youre also able to customize the sensitivity settings so that you are only alerted to movements that matter to you. With the built-in light sensor, it will automatically trigger the SwitchBot Bot to turn on the light if someone moves when the environment gets dark.
  • [Easy to Install & Long Battery Life] Thanks to its small and wireless design, SwitchBot Motion Sensor can be installed and set up in seconds. You can place it anywhere since its magnetic flexible base can be inserted to the bottom and side. The included battery provides up to 3 years of power for round-the-clock security.
  • [Part of SwitchBot Ecosystem & Compatible with Alexa] Connect Motion Sensor with other SwitchBot products and set up a Scene in the SwitchBot app. When you come home, SwitchBot Bot (button pusher) will automatically be triggered to turn on the light, and Alexa will say welcome home. When you leave, SwitchBot Indoor Camera will automatically turn on to detect indoor activity while youre away (SwitchBot Hub required).
  • [Remote Alert Notification] You will receive a notification if a suspicious person enters the house while you are away. (SwitchBot Hub required)

  • All good to great products but....
Color: Motion Sensor white
I havent run in to a product that has given me a difficult time setting up that switchbot offers. That said their devices staying connected is the issue. These are great but I'd caution after about 10+ of their products in the house things stop connecting, the app goes side ways and whole bunch of other cool annyoying things you get to do to keep them connected. So after this I have some time to kill have three button pushers that keep disconnecting and have to always delete and add back. If you need a hobby then get some switchbots connecting them few times a day in the app and grouping them in the app will give you hours of fun time ... show more

  • New 1.3 FW trashed it?
Color: Motion Sensor white
Worked great for over a year. After the latest firmware upgrade to 1.3 it hasn't worked again. I took a second one out of the box which got auto-upgraded and also never worked. Update: After 24 hours or so of not working, it now works again. I don't know if there was a fw update since 1.3 that went into it automatically ... show more

  • Great At Controlling Office Lights
Color: Motion Sensor white
The motion sensor is another addition to my Switchbot eco system, as a part of my smart house design. I have the Hub Minis, Bulbs, Plugs, and Thermostat/Hygrometer Plus, all performing various routines and automations, a total of 24 devices. All of the devices maintain connectivity to my network and router, and are simple to set up and manage wether its through the native Switchbot app, 3rd party apps like Simple Commands, or IFTTT, and my voice assistant "Alexa". For the office lights I went into the Switchbot app, performed the calibration for ambient light, and set up one for dim lighting and one for bright lighting. Created the required "Auto" routines/scenes to control the lighting. Now once motion is detected at the doorway the lights turn on and remain on while activity is taking place. I did need to set a condition for "no motion for 10 minutes" to assure the lights remain on while working in the office, but turn off automatically when the office is vacated. Switchbot has provide quality products for a reasonable price, they are my go to brand for smart home implementation! ... show more

  • Fantastic Little Motion Sensor
Color: Motion Sensor white
Positives: Easy to install Consistent performance Compatible with other smart devices Negatives: Occasionally fails to pick up motion Overall, the Motion Sensor is a solid choice for those looking to add some smart technology to their home. The installation process is straightforward and it works well with other devices. However, there are occasional moments when the sensor fails to detect motion. Despite this, the consistent performance and compatibility with other devices make it a worthwhile purchase. I would rate this product 4 out of 5 stars. ... show more

  • Features Not Good For Intended Use
Color: Motion Sensor white
Without getting multiple of these, you only know when someone (or thing) is there, not whether someone has arrived or is leaving. Even with multiple, you could not set up routines to run based on people arriving or leaving the area, which was the main selling point that the manufacturer was making. Fortunately, I was able to return it so it did not cost me. ... show more

  • No google assistance support.
Color: Motion Sensor white
I have to say I'm very disappointed based on their advertising they made. It seem like it worked with google assistant but it only works inside of its own ecosystem or with IFTT

  • Impressed at first but quality is lacking
Color: Motion Sensor white
Easy, logical setup. Great solution idea. However, doesn't see well depending on the light of day and if it's in a dark area you will need to leave a light on. The bot with the mechanical finger is junk. There is no other way to put it. I bought two and they each lasted 60 days. The price went up again so I'm done. I was using them with motion detectors to open my dog door. It became so frustrating with the dogs often being locked outside because the motion detector had either too much sun or too little or the bot breaking that I scrapped the whole project. Hub, motions, bots and batteries put me out $150 and HOURS of frustration trying to tweek and fix it. There are a lot of good reviews which I had for the first month too. ... show more

  • Have to Wait for it to trigger a second time
Color: Motion Sensor white
I have had several messages with tech support. I seem to be the only that has this problem. I have it connected to plug to turn on/off when entering exiting a room. It will turn on or off OK. But won't trigger again with a few minutes in between entering or exiting. Should have returned in the thirty day window. Won't buy again for now. ... show more
