Interested in reviews of SONOFF SNZB-05P Zigbee Water Leak Sensor & Detection Cable? It got 4.9 out of 5 stars from our customers. Find specific customer reviews of SONOFF SNZB-05P Zigbee Water Leak Sensor & Detection Cable below. We will appreciate if you also share your experiences with SONOFF SNZB-05P Zigbee Water Leak Sensor & Detection Cable after purchasing.
I give it five stars because I tried the detector (I put it in a puddle) and it works as it should. It's compatible with zigbee2mqtt, which is an absolute staple nowadays, and I certainly won't buy products that aren't compatible. This detector can be used in two ways: either just the box placed on the ground with the contacts facing downwards or the attached string is used, plugged into the contacts on the box, the string is stretched to where the leak is to be detected and as soon as a small piece of string gets wet, it immediately indicates a leak. The box itself does not alarm, you need to pair it with a zigbee gateway and set some action in it when a leak is detected. Now I can only hope that all the alarms that the box will cause at my house will be only test alarms and that there will be no real water leaks (it happened some time ago, the hose under the sink burst and water started coming out of it, so that's why I bought it).
On sale for 479, - CZK even with detection cable very good. In one package the braid of the detection cable was damaged and the inner wire was showing, in the other it was fine. Thanks to the detection cable, a larger area can be covered, detection with the cable works as fast as when using the sensor alone.
Works with HomeAssistant via ZHA
Coverage of a larger area with the detection cable, the detection works on the first level
Possibility of extending the detection by purchasing an additional detection cable (Alza does not sell this at the time of writing)
As the detection cable gradually dries out, it often changes state from dry to wet and vice versa (for example 20 times in a row, the more the battery is used up)

Good flood or leak sensor, works with both the electrodes themselves and the detection cable. Unfortunately, together this lineup is not the cheapest.
It works
Possibility of operation with detection cable
