### ⭐⭐⭐⭐⭐ All-round decent sensors
*by S***D on 28 January 2025*

For a while now, I've been using door and window sensors built on ESPHome, using regular hall sensors, hooked up to Home Assistant.It was initially an experiment to see whether I'd actually find a use for them (I did). They worked fine, but running cables for 4 of them looked messy.I decided to buy a Zigbee USB gateway recently, intending to try some 'kinetic wireless switches' (which didn't work) in order to control lights and provide some other automations. Since my original plan didn't work out, I figured it was time to see whether Zigbee was worth it.It is. It really is. It took me all of ~10 minutes to pair 4 of these sensors into HA (using the built-in zigbee integration) with no significant trouble discovering them. The response time of them is really good, and connectivity is decent.The installation is very simple, requiring only the removal of the adhesive tape cover and then pressing into place for both pieces. The detection range/sensitivity between both pieces is decent too. Evidently, the magnet used in the smaller piece is decently powerful.I don't yet had any insights to share on battery life. I'm hopeful that the 5-year estimate is somewhat accurate, but even if it only gets half the time, that still represents an extremely good value proposition.

### ⭐⭐⭐⭐⭐ Reliable door sensors
*by W***L on 13 April 2025*

I'm using these on a couple of bathroom doors to tie in to Home Assistant and automate the lights.A couple of months in I can confidently say they're working very well, no connection drop outs and very reliable detection of opening/closing.Bit early to comment on battery life but looking at the reported numbers they seem like they're going to live up to the promise.For the price I'm comfortable recommending these.

### ⭐⭐⭐⭐ Works well with Home Assistant
*by M***M on 6 February 2025*

Works well with Home Assistant. Strange battery; hopefully, it works for a good while.
