eufy Security, Entry Sensor, Detects Opened and Closed Doors or Windows, Sends Alerts, Triggers Siren, 2-Year Battery Life, Indoor-use Only, Requires HomeBase S280 or HomeBase S380

Easy to install, worked straight away

Ordered to add to my Eufy system. Fitted to Shed door. Works flawlessly. Battery lasts a long time.

I have already purchased one of these and was apprehensive the first time that I had to install and configure it on a Homebase 2 Hub...but it was simple and has worked reliably ever since, even after I upgraded to a S380 Homebase 3 Hub. I have now bought another sensor to use within the same installation and it installed even quicker using the EUFY security app on an Android handset and is simple to label and to select a sound, if required. Now I intend to forget about it because it works without fault and battery seems to last forever. To be honest...an excellent item, reasonably priced, well constructed and RELIABLE. Not often that I can say that about technology. Buy with confidence. Arrived next day too with Prime. Many thanks EUFY. (FYI...ensure that Homebase and ethernet hub are located in a ventilated area and cannot overheat as this will cause problems with remote access to storage. It says it in the instructions too. Thought I'd mention it...always learning.)

This was amazingly simple to setup and connect to my Homebase 2 that I already had setup with my Eufy Cameras. It sticks in place with 3m stickers and sends notifications to my iPhone and Apple Watch when the windows are opened or closed. The history of events are shown in the app so you can review things.Eufy seems to be setting there products priority for privacy in terms of everything being processed in your house rather than being sent to a server where your data is potentially being harvested, leaked, or sold. This is very impressive in times when we are worried about privacy. It also has the benefit of removing a monthly subscription! Think about how much of a trick others companies are....”buy our over priced camera, pay us a subscription to be able to look at your recordings, we get to look at your data!”. With Eufy this is not the case. Free to use and private.However......I may have to return these as they don’t quite meet my needs/expectations. The cameras integrate with homekit and therefore other smart devices. These just say door is open, door is closed..alarm on base station goes off.....that’s all. They can’t turn your lights on or off or even set the alarms off on other eufy cameras which seems daft.They do what they say they do very well. Easy, simple and private. However I feel that in today’s smart home they need better integration with at least the companies other products. Hopefully it’s just a software update and a flick of a switch.

A lot smaller than pictures suggests.Very impressed. Easy to install and connect to system.Wifi range is impressive.Sleek and stylish (for a door sensor)Only just installed so can not comment on battery life
