Eve Door & Window (Matter) 3 Pack – Smart Contact Sensor for Doors & Windows, Open/Closed State, Automatic Control of Accessories, Matter Over Thread, Apple Home, Alexa, Google Home, SmartThings - desertcart.com

Review: Eve Door & Window (Matter) 3 Pack - I have many of these sensors that I've purchased over the past few years. I keep buying them because they function as expected. Their response time in logging is good. ease of install? Matter makes installing and adding these devices to Apple Home super easy. As far as durability, I dropped a sensor and now the toggle for reset is no longer aligned with the tiny hole in back. Overall, I'm happy with all my Eve Home products.
Review: Reliable & fast contact sensor trigger w/thread - I've got HomePod Minis and Eve Energy devices so I'm using the Eve Door & Window with thread. They come with plenty of spacers to adjust the non-battery powered passive part of the contact sensor. So depending on your door or whatever, most people should find a way to make these work. The battery cover is hard to install and feels like you're forcing it on -- so I'm concerned that battery replacement might be frustrating. So try to be sure there's a way to remove the active sensor from the battery door, which is done by sliding away the sensor body. Those are the only negative things I can say about these devices. Importantly, the both my Window and Door contact sensors already had the new Thread firmware (purchased in July 2021). So I did not need to upgrade their firmware. At first when I added an Eve contact sensor, it didn't trigger automations reliably. So I rebooted all my Eve Energy and HomePod devices. Since then they've been working flawlessly, every time, and near instantly. I have one contact sensor that turns on the hallway lights when the closet doors are opened, and turns them off when closed. I have another sensor on a slider that we only open up to let fresh air in. So I set up an automation to put our Ecobee into away mode to keep the AC or heat from turning on when we have the windows open. They've been extremely fast, triggering within a second of opening or closing. By using the Eve app I can see that so far these contact sensor Thread end-points are relaying their activity to an Eve Energy thread router that is about 30-40 feet away with several walls. That's impressive range and I'm surprised they're not routing through closer HomePod Minis or NanoLeaf Essentials bulbs. I plan on buying more of these devices soon as I can think of more practical, life improving things to do with them :-)

## Questions & Answers

**Q: When using the iOS platform - can I combine Matter and HomeKit-enabled accessories in an automation or scene?**
A: Yes you can. For automations, Apple Home makes no difference whether your devices were added to your home through HomeKit or Matter.

**Q: Eve Door & Window is a Minimum Thread Device (MTD) – but what does that mean?**
A: Thread makes your smart home network more responsive, the only other thing you need is a home hub (Thread border router). Battery-operated Thread accessories, such as Eve Door & Window, represent endpoints in your Thread network.

### ⭐ STAY AWAY FROM THIS ITEM
*by L***H on October 28, 2025*

Good while it works but then it start disconnecting from homekit and you add back and then in a few days same thing until eventually dies. Very hard to get a warranty replacement stay away from this. Bough like 5 and they already not working less than 5 years.
