The Eufy ecosystem is very good, I’ve had it for five years now. Just needed more entry sensors which was easy to synchronize or connect to the WiFi and the system and it works well. The adhesive is good, it sticks properly to the surface of my window really good. I would recommend the entire Eufy ecosystem if you want a reliable security system for your home. Remember you can set up the entire system yourself. It’s that easy.

An all-round great product, set up was easy, and they are super reliable. I just took them out of the box, loaded the included batteries into them, and placed them on my door and door trim, and it worked like a charm. The adhesive strip on the back of them allows you to readjust the sensor and magnet a few times without losing any strength, so you can find the best spot to place them, making sure the gap between them is less than 4cm. When testing, I armed the security system and opened the door as if I were an intruder, and the alarms started blaring instantly. I also got a notification on my phone as soon as it happened. No regrets adding this to my security system

Handy, easy to install and add to the app, lots of options for notifications so they don’t annoy you. Would repurchase and recommend

Lots of potential. Hardware is very well designed. Software feels like it’s still under development. We’ve recently purchased many eufy security products. These sensors pair easily to my eufy homebase 2 and read the door’s open-close status reliability. However, Because of the software, they seem pretty useless. Right now, I can “arm” my eufy security system and an alarm will sound when the door is opened. That’s good. But the app requires many taps to arm/disarm the system and there’s currently no integration with other systems like HomeKit or August. I expect one big button to arm/disarm all my smart home security devices. Adding integrations to arm/disarm the system or Siri Shortcuts would be a big improvement! Additionally, the sensor has no chime feature with the homebase making it useless unless the system is “Armed”. It would be very useful to hear a pleasant chime from the homebase or the eufy video doorbell chime when my young kids open the door unsupervised. Ultimately, it’s a neat add-on to my eufy cameras, but features seem a bit raw or missing. I’m hopeful eufy will continue development. Update: Anker emailed me about my review and apologized for the experience. As part of the apology they sent a cool little battery bank. I’m glad they care and are paying attention. I hope this means they’re adding my requested software changes. Unfortunately for Anker, my review doesn’t change until they change how this product integrates with the rest of the system. More updates: Anker/eufy has continued to pursue total satisfaction. I must say I’m impressed. If they’re product development work’s nearly as hard as their customer service, they’ll be adding my requested changes in no time. Along with this update I must mention an announcement by eufy at CES 2020. Eufy is releasing a new keypad with home/away buttons thereby satisfying one of my major complaints with this system as an alarm. I am increasing my rating from 3 stars to 5 stars out of optimism for future updates as well as outstanding customer service. Update 7/8/2020 The requested door chime feature has been added. Now a pleasant chime is made by the hombase2 when a door is opened. They still lack in integration even among their own products. If I arm the alarm system, (camera, motion, and door sensors paired to the homebase2) other devices like the floodlight cam outside are unaffected and do not switch into an “away” mode without additional action in the app.

It'd be Great if it could support Apple Homekit.
