Updated review 11/14/22 and reinstated 5 star rating:Apparently, during the last week or so of October 2022, there was a software issue of some sort between this device (contact & motion sensors) and my Echo Show. I think it was a zigbee issue. A lot of users of zigbee-enabled devices complained about it on reddit. I don’t know the exact problem because it’s all hush-hush, keep the customer uninformed. Apparently, it was corrected by Amazon after approximately one week. My Third Reality zigbee contact and motion sensors all work beautifully at the moment. Until the next glitch, of course. I reinstated my original 5 star rating because I really like how these devices work for me (except for the glitches, of course).—————–Updated review 10/31/22 and 1 star rating:It worked great, until it didn’t. It disconnected from Alexa and won’t reconnect. The sensor itself works. The red light lights up when the door is open, but what good is a sensor when Alexa can’t tell you the door is open?———————Original review 10/13/22 and original 5 star rating:This device works with my Echo Show with zigbee. I asked Alexa to “find my device” and she did. I didn’t need any other hub, app, or skill, and I like that it’s not wifi. I purchased a couple to use on interior doors at night so I know if a door opens or not. I set up an Alexa routine. In my house, Alexa announces the door is open within 3 seconds of opening the door. There is no down or recovery time. It’ll work again within seconds.I’m very happy with it and its easy integration via zigbee with the Alexa app.

Love these. They work well and use standard batteries

I paired this contact sensor with Aeotec SmartThings hub to automatically turn on foyer lights when someone opens the front door. I was worried because my lights are z-wave, and this contact sensor is Zigbee, but everything works well because Aeotec supports both technologies. The sensor is responsive, i.e., sufficient sensitive.The only issue is that it’s difficult to open the thin part (the one with the magnet) if you want to screw the base to the door frame. I end up using needle nose pliers and a screwdriver, but it’s still unnecessarily complicated.

I only needed a basic contact sensor for a side door and was pleased when it paired easily (about 15 seconds) with my Version 2 Smartthings Hub. I use Home Assistant, not Alexa or Google Home, and the door sensor was in operation within a minute after reloading the Smartthings integration. I didn’t use the adhesive pads because they looked a little thin to me. I instead use the the thicker Gorilla double sided tape because it lasts seemingly forever and can be easily removed when no longer needed.

For some reason this was a pain to attach to my Zigbee network but once it was picked up it’s solid.Very fast to report state change and is able to have a gap of more than 1 inch.Uses AAA batteries and has screw mounting holes in the base plates which is a huge bonus.

Works fine. Seems like better life is good and stays connected to hub.

installed the batteries and it paired with my Hubitat C8 almost immediately. Attached it to a pantry door to automatically turn the pantry light on and off. The sensor seems to trip when separated 3-4 inches.

I use the SmartThings hub to bring some devices into my ecosystem for overall control via Home Assistant and using Node Red. I used this for a garage door sensor and was looking for sensing with a larger gap between sensor and magnet. In my installation this has a .5 inch gap and contacts reliably. It added easily to the SmartThings hub. Battery life is TBD, but I was able to monitor contact Open or Closed and also battery level through SmartThings. In Node Red I set up my monitor routine for contact status but was also able to monitor battery level so I will get notification of low battery as SmartThings will not tell me if the sensor has dropped off from the hub. Sensor is fairly small and I was able to mount it in minutes with included double sided tape.

I recently purchased 3 of these for our doors at home. They have been mounted with the supplied double sided tape. I added them to a Hubitat C-8 hub. Each sensor was added to the hub quickly and without any issues. I like that these use standard AAA batteries. The price on these is very reasonable and I definitely recommend them.

These connected easily to Home Assistant and work reliably. So far only one of the 10 I bought has dropped the connection and required me to re-setup. The one that dropped is also the furthest unit from my server, so it’s understandable.
