*** SEE UPDATE BELOW*** I own several Meross smart plugs and a garage door opener, and those work flawlessly. I expected nothing less from this Door/Window sensor. Meross did not disappoint. Installation was easy (no tools needed) and with the Meross App, once it connected to my home network Alexa immediately found the unit and added it to my device list. I was then able to create routines that would have Alexa announce every time the door opened and again when it closed. You can create routines that meet your needs (turn lights on, start appliances, etc.). This is compatible with Apple HomeKit, Alexa and SmartThings. For this unit, the Meross App will show the current status of the door (opened or closed). I placed this unit on the service door to my garage. This door is probably the most vulnerable as it is hidden from the street and not direct line of sight visible when entering the garage from the house. We now know, with certainty, whether the door is open or closed when we go to bed at night. We will also get a verbal notification should the door be opened at any point in time. The included HUB can control up to 16 Meross devices, so it could handle a house full of sensors. ***UPDATE*** After 3 months of use, I find that the battery that runs this unit has a very SHORT life span. This uses a CR245 Lithium Coin (button) Battery. The battery is lasting only about 30 days! I was able to find a 20 pack of this battery for about 50 cents per battery, so the cost is not exorbitant, but changing the battery every month is annoying. I won't change my rating because of this, but just wanted everyone to be aware of this fact. ***END OF UPDATE*** 5 STARS AND I DO RECOMMEND THIS ITEM I write honest reviews based on real life experience with each item to help others make informed purchases. I read reviews too, and appreciate how helpful they can be. I hope that you find this review helpful.

I bought the water leak sensor with the hub and one door sensor because it has a hub which is required. It turns out that only one item can be attached to one meross hub at a time. I attempted to attach the leak sensor and window sensor on the same hub and it kicks the other off because the home kit label is on the meross hub not the item( water leak or window/door sensor) which means you cannot connect each item to homekit seperately if you already own a HomePod. So you would need a separate meross hub for every sensor which is insane, Where would one plug in all of these hubs for multiple windows and doors? Meross should be ashamed for selling such garbage. I am so disappointwd in this product as all my light switches are meross. I would not recommend the window sensors. MEROSS PLACE A HOME KIT CODE ON THE ITEMS AND STOP FORCING CONSUMERS TO BY YOUR USELESS HUBS which have weak connections.. The purpose of HOMEKIT IS TO USE THE HOMEPOD AS A HUB/BRIDGE

UPDATED REVIEW - The hubs have been working pretty well now for a few weeks. Meross replaced 2 apparently defective sensors, and I now have a total of 2 hubs and 6 sensors which are "up" 90% of the time, when they go down it is mostly me making changes on my router. I am now pretty confident in them. ORIGINAL REVIEW - I bought 2 kits with the hub included and 2 more with just the sensors. They are all pretty unreliable. The good: 1. The hubs and sensors are small and unobtrusive. The bad: 1. The battery tray / holder / slot is too loose. The batteries will slide around / move if you have this part of the setup mounted on a door that is opening and closing. Battery will move and unit will lose power. I suppose it would happen less if this part of the sensor was mounted on the door frame or windowsill and not on the part that is moving. I tried using Scotch tape to hold the battery in place, it helps some but not enough. Other reviewers have said they turned the sensor upside down so the battery dose not slide down, this might work, you need to play with the setup. The sensor that contains the battery is one part of the equation, the other part is just a magnet in another piece of plastic. 2. The "hub" constantly looses connection to WiFi. I have something like 52 devices connected to my network, quite a few of them are Meross devices, but these hubs are very delicate / sensitive / garbage? In summary, the idea is nice I own quite a few Meross devices, but these are not reliable, especially taking into consideration they are meant to notify you if doors or windows are open. it's much different than an ambient light not responding.

The media could not be loaded. Best product for automation. When I open my closet door the light turns on automatically. Very good price.

Don't buy this sensor kit. It only worked for couple days and then keeps disconnet with my wifi at least twice a day.

Installed 7 of these, all worked great. Next day, 2 of the sensors weren''t responding. Had to disassemble to see the battery wasn't making good contact. I like the product, but not sure how long they will last or will stop working because battery is loose.

I have most of the home with Hue sensors, but switched to these meross to check them out. Easy to install, and much more affordable. They connect and work with HomeKit just as easy.

This is the worse hub/sensor I have used. It only works for a few hours and stopped working. I thought it was the battery and I changed it, the issue continues until now. This is a disaster hub if you ask me. My advice, don’t buy it.
