Ubiquiti is pretty good about HA integration, so I decided to take a chance buying one of their new line of sensors. It’s a door/window sensor that also senses motion, light, temperature, humidity, and (somehow) leaks.
You either need their proprietary (boo) superlink hub or a U6 series access point for the sensors to work. I have the latter. Everything gets reported to HA immediately as expected. My only complaint is that you’re unlikely to need or want every single sensor in the same place. I still don’t know how the leak detection is supposed to work on a door sensor. It uses an uncommon battery size, and cramming all those sensors into a single package makes it an expensive purchase compared to other brands, especially if you purchase directly from Ubiquiti.
All in all it does what it’s supposed to, and I suppose it’s worth the cost if you need all those sensors in one place.
But I think that’s a pretty specific use case that’s kind of narrow. The water sensor is out of place there because normally you’re putting those under sinks, near toilets, etc. I’m never using that in Seattle because everything is always wet here.
