Xiaomi Window and Door Sensor 2

Xiaomi Window and Door Sensor 2 Price in Kenya

The Xiaomi Window and Door Sensor 2 price in Kenya is Ksh 2,000. This is the most affordable way to secure your home and start automating your life. While the first generation was just a simple open/close trigger, this 2nd Generation model is a “2-in-1” device that adds a Light Sensor. This means it doesn’t just know if the door is open; it knows if it is dark when the door opens. For security, it acts as a silent sentry. Stick it on your main door, windows, or even the cookie jar. If triggered while you are away, it sends an instant notification to your phone (requires a Xiaomi Bluetooth Gateway). For automation, it is the magic switch. Imagine opening your door at night and your living room lights turning on automatically, but staying off if you open the door during the day. That is the power of the new light sensor.

Important Note: This device uses Bluetooth 5.1. To receive alerts on your phone when you are outside your house (remote access), you must have a device that acts as a Bluetooth Gateway (like a Xiaomi Smart Hub 2, Xiaomi Smart Camera, or Xiaomi Bedside Lamp). Without a gateway, it works only when your phone is in Bluetooth range. Buy it today at Exelic Gadgets. Stock is available now.

Why You’ll Love It (The Lifestyle Upgrade)

• The “Did I Close It?” Cure: Ever leave the house and wonder if you shut the balcony door? Check the Mi Home app instantly, so that you stop panicking about rain or security.
• Smart Lighting Automation: Set it to turn on your Yeelight bulb when the door opens, but only if it’s dark, so that you never have to fumble for a switch with grocery bags in your hands.
• The Fridge Police: Stick one on the fridge door. It will alert you if the door has been left open for more than 1 minute, so that you don’t spoil your food or waste electricity.
• Instant Intruder Alert: If the sensor breaks contact while “Armed Mode” is on, your Xiaomi Hub can sound a siren and alert your phone, so that you can catch unauthorized entry immediately.
• Pet Monitoring: Put it on a pet gate or cat flap. You’ll get a timeline of exactly when your furry friend went out or came in, so that you can track their routine.
• Invisible Design: It is tiny, white, and minimalist, so that it blends into your white door frames or windows without looking like ugly industrial security gear.

Deep Dive: The Tech Explained

The 2-in-1 Sensor (Light + Motion)

The biggest upgrade in the Gen 2 is the Light Sensor. The original sensor was blind—it only knew “Open” or “Closed.” This new version measures ambient lux (brightness). This is crucial for smart automation. You can create a rule: “IF Door Opens AND It is Dark -> Turn on Lights.” This prevents your smart lights from turning on unnecessarily during the day, saving energy and extending bulb life.

Bluetooth 5.1 BLE vs. Zigbee

The older Xiaomi sensors used Zigbee. This new version uses Bluetooth Low Energy (BLE).

• The Benefit: It is easier to pair and uses very little battery.
• The Catch: Bluetooth has shorter range than WiFi. To control this sensor from work or get alerts when you are in town, it must connect to a “Bluetooth Gateway” in your house. Many Xiaomi devices you might already own (like the Mi Bedside Lamp 2, Mi Smart Clock, or Mi Home Security Camera 2K) have this gateway built-in. Check your existing devices!

“Left Open” Alert

This is a lifesaver for parents and forgetful people. You can configure the sensor to send an alert if the door/window has been open for a specific time (e.g., 1 minute). This is perfect for freezer doors, front gates, or windows during the rainy season in Nairobi. It nags you before the damage is done.

Event History Timeline

The Mi Home app keeps a detailed log of every interaction. It doesn’t just say “Open”; it says “Opened at 14:02” and “Closed at 14:05.” This is excellent for monitoring cleaner arrival times, checking if the kids got home from school, or seeing if someone entered your private office while you were away.

Who Is This Perfect For?

• The Smart Home Starter: You bought a Xiaomi bulb or camera and want to try automation without spending thousands.
• The Nervous Renter: You live in an apartment and want to know if your landlord or maintenance entered while you were out.
• The Eco-Conscious: You want your AC or Fan to turn off automatically the moment you open the window to save KPLC tokens.

Alternatives & Competitors

• Xiaomi Door Sensor Gen 1 (Zigbee): The Old School (Faster response time, but requires a Zigbee hub and has no light sensor).
• Tuya/Smart Life WiFi Sensor: The Hub-Free Option (Connects directly to WiFi, but consumes battery much faster and is often larger).
• Ring Alarm Sensor: The Expensive Choice (Great ecosystem, but costs 3x more and requires a paid subscription for some features).

Frequently Asked Questions (FAQs)

• Q: Do I need a Hub/Gateway to use this? A: For remote access, YES. You can see the status on your phone via Bluetooth if you are standing next to it. But to get alerts when you are at work, the sensor must connect to a Xiaomi Bluetooth Gateway (like the Mi Smart Hub 2 or a compatible Xiaomi Camera).
• Q: Does it have an alarm sound? A: No. The sensor itself is silent. It is just a trigger. It can make your phone ring or make a Xiaomi Hub sound an alarm, but the device itself makes no noise.
• Q: What battery does it use? A: It uses a standard CR2032 coin cell battery. It is included in the box and typically lasts about 1-2 years depending on usage.
• Q: Does it work with Alexa or Google Home? A: It works best with the Mi Home App. Integration with Google/Alexa is possible if you have a compatible Gateway, but functionality is often limited to asking “Is the door open?” rather than triggering Alexa routines.
• Q: Can I stick it on a metal door? A: Yes, but metal can interfere with the magnet. If you find it isn’t triggering reliably, place a small piece of cardboard or thick double-sided tape between the magnet and the metal door to create a buffer.
