## Description

SONOFF SNZB-04P Zigbee Door Window Sensor, Send Alert to Your Smartphone for Home Security, Compatible with Alexa/Google Home, SONOFF Zigbee Bridge Required, Batteries Included : desertcart.co.uk: DIY & Tools

Review: Excellent door and window sensor with tamper alarm too - This door and window sensor is great, it joined my zigbee network instantly and works through my home assistant. I really like the included tamper (vibration) sensor too so you can set it to notify you if someone or something is fiddling with it. Battery life is excellent with it being zigbee, I have had it a month now and its only down by 1% Ill get a few more of these I think.
Review: Excellent - Happy with this purchase so far. I sticked it on the bathroom door and it triggers the dehumidifier and the air con as I have no natural ventilation in the bathroom. The Zigbee bridge that I'm using is an AEOTEC USB stick connected to my Raspberry Pi5 server with Home Assistant. I had no issues at all with connectivity - the device was discovered instantly by my network. Good sensitivity, very nice quality of plastics used for making the product and feels durable. Baterry life looks fantastic - after a month of use the battery is still 100%. I hope it will stay like that. Good value for money, and overall a pleasure to use Sonoff products.

### ⭐⭐⭐⭐ Connectivity can be difficult to perfect
*by F***M on 4 March 2025*

Initially very poor connectivity on a couple of sensors ( a temperature sensor and a door opened sensor), with one needing regular restarts. After a lot of fiddling with repeaters in the same room as the sensors, the temperature sensor is working fine with no drop outs. However whatever I try, the door opened sensor still regularly drops out for an hour or so, and then reconnects. At least it does not need restarting. Now all my 6 temperature sensors are working flawlessly, after very attentive support from the seller, I am upping my review to 4 stars. I guess batery powered zigbee devices are very sensitive to the zigbee signal and this may not just be a Sonoff issue.
