Review: ⭐⭐⭐⭐⭐ 5/5 – Small Sensor, Big Impact - The SwitchBot Smart Motion Door Sensor is a fantastic addition to my smart home setup. Installation was quick and painless—just stick it on the door and pair it with the app. It’s small, discreet, and feels well-made. The sensor is very responsive. I use it to trigger lights, alarms, and other smart devices, and it works flawlessly every time. I especially like the notifications—knowing when a door opens or closes gives extra peace of mind. Battery life has been excellent so far, and replacing it is simple. It integrates smoothly with other SwitchBot devices, making automation easy and flexible. Whether you’re looking for added security or smart home convenience, this sensor is a reliable choice. Highly recommend if you want a simple but effective way to make your home smarter.
Review: Perfect solution for automating a bathroom extractor fan - I bought this SwitchBot motion sensor specifically to automate my bathroom extractor fan, and it has been absolutely brilliant. I paired it with two standard SwitchBot Bots (one positioned to turn the fan switch on, and the other to turn it off), and the whole system works flawlessly. The setup solves two major annoyances in our house. First, dealing with shower steam. Now, as soon as someone walks into the bathroom, the sensor detects motion and triggers the "On" Bot to start the extractor fan immediately. To make sure it clears all the residual steam without running all day, I set up a simple automation in the app: once the sensor detects no movement for 15 minutes, it triggers the "Off" Bot. The absolute best part, though, is the scheduling feature. Bathroom fans can be incredibly noisy, and I didn't want it waking up the whole house during late-night bathroom trips. The SwitchBot app let me easily set custom active hours, so this automation completely disables itself after 22:00. It took a little tweaking to get the Bots positioned perfectly on my specific switch, but the sensor itself is incredibly responsive, and the app works exactly as intended. Highly recommend if you want to make a wired bathroom fan smart without messing around with the mains wiring!

## Features

- [Motion Sensor Detects Your Movements] With a motion detection range of up to almost 30 feet within 110° horizontally and 55° vertically, there’s more than enough range to secure an entire room of your home. You’re 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 you’re away (SwitchBot Hub required)
- [Energy & Money Saving] By detecting the room vacant, Motion Sensor automatically turns off the lights, reducing unnecessary energy consumption to save you money.
- [Remote Alert Notification] You will receive a notification if a suspicious person enters the house while you are away. (SwitchBot Hub required)

### ⭐⭐⭐⭐ Good product but slow response
*by L***O on 11 April 2025*

[ETA] Switchbot have been in touch and their Customer Services & Support have improved to the point where I felt it necessary to re-review my review & the product. I use it in my 'broom cupboard' and it is pointed directly at the door. It takes a moment for the indicator light to signal it's interaction & acknowledgement of my motion. I assume this is the delay caused by relying on web-server-side activities instead of local-based. As I'm only in the cupboard for a few seconds (returning the mop, throwing shoes in there, etc.) the bulb comes on just I'm shutting the door again - somewhat defeating it's purpose. However, it works just fine for longer periods - keeping the light on as needed until the door shuts. In terms of quality, it's a sturdy build and the magnetic base affords great potentially awkward spots being accommodated as it can be stuck to any metal surface. The device is very easy to set up with the provided app which covers all of SwitchBot's devices & ecosystem and thus the phone can be used to log events. I've generally been happy with the product bar the aforementioned sluggish response-time.
