## Description

Door and window sensor can directly work with compatible ECHO. And its compact design can fit in most doors and windows. Most of the doors or windows have a height difference from the doors' or windows' frame. With the special design the height difference can be reduced to make sure the two parts of the door sensor have a stable contact. Simply peel off the protective layer of double-sided tape and stick the two parts of the door sensor to the door and the door frame. You can monitor every door and windows in your home and create routines to send messages to your smartphone when the door or window is open. You also can create routines that are triggered by the on/off status of the door sensor.

### ⭐⭐⭐⭐⭐ Review
*by R***B on 5 January 2025*

I bought 12 of these to replace all of another brand (S*O*N*O*F*F) which uses 2032 button cells, they paired with any of the Hubitat models within about 10-15 seconds whether they were 1m or 10m away. The driver it picked up was the built in Generic Zigbee Contact Sensor (no temp) They all needed an upgrade from 0x30 to 0x3F which was easily done via Hubitat within about 10mins, about 60 secs per 10% block, the progress can only be seen in the live logs for the Hub. This gives you: Optimized the network joining and reconnecting algorithms Optimized the power detection logic Optimized the trigger filtering algorithm From what I have experienced, the upgrade procedure is well protected and never bricked any of them, each 10% block is transferred and checksumed, at 100% the upgrade is transferred to its flash memory. The device still has live operation during the upgrade process. I made a mistake on the first one by unpairing/re-pairing while it was upgrading, simply because I did not realise anything was happening viewing the device page. When I found where I could see the progress, it had stopped at 30%, after 2 mins I realised the upgrade had been cancelled by my actions without any harm. The upgrade was just started again and completed without error. The great thing about these 3rdReality devices is that they use a modern hall effect sensor to trigger via the magnet instead of an antique reed switch, so they can be mounted offset slightly on windows and doors, the max detection range is about 25mm so best to stick with 15mm or less if the magnet is not on the same plane. As long as you dont have any poor/ chatty/ proprietary Zigbee protocol devices on the Hub and have good plug in repeater mains sockets between far off devices to create a good Zigbee mesh they operate automations in Rule Manager within a second , no matter how far away they are from the Hub. I am very impressed with this brand and have purchased 8 Temperature/Humidity lite sensors, again uses 2 x AAA supplied and also a couple of the waterproof soil moisture/temperature sensors to assist in the automated garden watering .
