Sonoff Zigbee Door/Window Sensor

by Sonoff

Batten down the hatches! Keep your doors, windows, and cookie cupboard safe and secure!

The Sonoff Zigbee Door/Window Sensor is a low cost and solution for monitoring your doors and windows within a smart home setup. Use it to easily check that you haven't left a downstairs window open at night or to automatically turn on the bathroom light when you open the door.

It comes with a battery pre-installed that will last for over five years allowing for minimal maintenance. Installation couldn't be simpler, just use the included 3M adhesive tape to fix the sensor and magnet modules to the door/window and the frame.

Security and savings

If you live in household where the kids forget to close the garage door after a bike ride or your partner leaves windows open while the central heating struggles to keep up then these handy little sensors are just what you need!

Within your home automation setup you can create rules for what happens when a door or window is opened or closed or if it is left open for a specific period of time. These rules can trigger notifications or events such as turning a light on or off. You can also easily, at a glance check the state of all of your monitored doors and windows.

To use Zigbee devices you'll either need a Zigbee compatible USB dongle connected to an always-on computer (a Raspberry Pi is ideal!) or a dedicated Smart Home solution like the awesome Home Assistant Green (+ Zigbee Donel) or Sonoff iHost.

Why we love it

What is Zigbee?

Zigbee is a wireless standard enabling low-power, secure connections between smart devices. Widely used in home automation for devices like thermostats, sensors, and locks, its energy efficiency allows some devices to run for years on a single coin cell battery.

It has many benefits but the biggest one for us is its local nature, there's no cloud subscription or even internet connection required - everything stays within your home if you want it to. This makes it both incredible secure and also resilient to internet connection outages.

Many big brands have Zigbee supported devices including IKEA, Philips Hue, Tuya, and of course Sonoff. This means you can combine devices from different manufacturers into the same smart home setup ensuring you're not locked in to a single vendor - nice!

With an indoor range of 10–100 meters and extended outdoor coverage, Zigbee’s mesh networking ensures reliable communication, even if some devices go offline. Security features, including encryption and key protection, safeguard your smart home, keeping it secure and under your control.

A bit overpriced in comparison of most other BME680 sensors available online but with this one, you're sure it's working with the Adafruit libraries. I had this issue when buying 2 BME280 sensors from China, one of the two was actually a BMP280 in stead of BME280 so, it couldn't work with the library even if written on the article description as compatible.

Love the BME680. Very easy to install and the Example files are great for getting started. Have found out from this Pimoroni Forum post : https://forums.pimoroni.com/t/bme680-air-quality-low/6293/9 that the whole AQ subject is very complex, however It's a really interesting topic and one that I am looking forward to understanding better! I'd assumed that it was only detecting VOCs (volatile organic compounds) but there's a hint that it might be detecting other gases. (I'm using a Breakout Garden pHAT with PiZero W, BME680 and 11x7 matrix to show an AQ score.)

I appreciate the thought put into the design of this board. It is nice that the pins line up with the GPIO, it’s easier to assemble and more presentable to have around the house. I also appreciate that their software has a “try” statement that looks for an Adafruit addressed chip as well as this Pimoroni one, since I have a mix of both around. Very good product, very much recommend it!

The board is high quality and easy to mount (on a featherwing proto) - note to Pimoroni (perhaps you could develop sensors already mounted on featherwing format?). The driver software is a little harder to get working than I expected - still can't see have to get the AQI (air quality index) as an output from the Bosch library or through the wrapper Adafruit library.

I am glad I lived long enough to see this awesome technology! I was a bit out of practice with the soldering iron but even I managed to sort out the connection to the Raspberry Pi. It is now being used to monitor the environment in conjunction with a ground source heat pump via Home Assistant. Thank you very much!

Very nice all in one sensor for most basic Environmental sensors. The Air Quality sensor (Gas Ohm resistance detection) does take awhile to stabilize (at least 20 min on first start, about 5 for ones after that). It might get better as I use it more, as I only used it for about 12 hours.

Up and running in minutes after a false start but recovered quickly owing the prompt technical support. Good excuse to refresh minimal soldering skills. Robust module supersedes previous models. Temperature (with humidity) sensors are a dime a dozen, the barometric sensor is an added plus but the air quality sensor is the deal breaker for the price.
