## Description

SONOFF DW2 WiFi Wireless Door Window Alarm Sensor with Phone Alerts, No Hub Required, Works with Alexa & Google Home, Low-battery Reminder, 2.4GHz WiFi Connectivity : desertcart.co.uk: DIY & Tools

Review: wifi contact sensor - works a treat, the single AA battery has lasted well over and year, it has not lost connection once. And it triggers every day to alert me via Google Home. Considering it requires no bridge device (as it's wifi connected) its a fantastic bit of quick for a good price
Review: Not Fit for purpose - I was impressed how easily these were to set up electronically. Although I did have a little difficulty in siting the one on a door that did not close flush with the frame as both the items need to be lined up flush. Initially I was quite happy with the setup. So much so that I nearly ordered more. However, 24 hrs later and I was being advised to change the batteries. after a further 12 hrs they stopped working. Maybe I had a bad batch of batteries. Bought new batteries and fitted them. Hey presto everything working fine again. That was short lived. 12 hrs later I'm being advised to change the batteries. So unless you intend to change the batteries every day then they probably aren't what you want. Easy to set up but a nightmare to maintain! I would have expected the batteries to last at least a month! Steer Clear!

## Features

- [ Phone Alerts ] Receive real-time notifications on your phone for door/window status changes from the eWeLink App- no hub required. (NOTE: No built-in siren, but alert your phone.)
- [ Low Battery Alerts ] Real-time battery level monitoring and low battery alerts via the eWeLink app prevent 'insecure time' due to 'low battery'.
- [ 30-Second No-Tools Installation ] Easily stick, and secure on doors, windows, cabinets, or garage surfaces without drilling or wall damage ( removable for hassle-free adjustments).
- [ Work with Alexa & Google Home ] You can integrate the sensor with Alexa and Google Home ( paired to the eWeLink App at first) for door status checks through voice.
- [ Voice Alarm& Smart Scene ] Connect this door sensor to the SONOFF hub/camera with a built-in siren for instant alarms – when triggered, the hub/camera sounds an alert to secure your home. It can also trigger the SONOFF camera to record or the SONOFF light switches to turn on.

### ⭐⭐⭐⭐ Failed after 42 days! UPDATE! All okay again now!
*by L***N on 1 February 2023*

This Sonoff door/window switch worked fine initially but this morning, 42 days after I installed it, it is completely dead. No LED light, flashing or on solid! I replaced the batteries but still no good. I have now found out that the Returns Policy is for up to 30 days! So it didn't last even 2 weeks past the Returns cut-off period! If I order another one I am worried about how long that will last! Has anyone else had this problem or have I just been unlucky? UPDATE. Replaced the battery (again) and re-paired it - and it works again! Not sure what the problem was, but all okay now and it is behaving itself perfectly! Since buying this one I have bought another one and they are both working fine. One turns on a light in the understairs cupboard and the second one gives me an audible warning and flashes some lights (via Alexa) that the outer front door has been opened. I might get another one for my back door! :) Edited this review to show 4 stars out of five!
