Zooz 800 Series Z-Wave Long Range Open|Close XS Sensor ZSE41 800LR for Door, Window, and Gate Monitoring. Hub Required (Sold Separately). Compatible with SmartThings, Hubitat, and Ring Alarm.

I bought this to add to Alarmo on Home Assistant via Z-Wave JS. This comes with instructions for pairing.-Pros:-Pairing is easy as 1-2-3. I question your intellect if you struggle with pairing this device.-There are 7 different sounds. Several are meant for use as a doorbell, and others as a siren for an alarm system. Some are louder than others, but there is a particular one (#7) that is absolutely loud. It's the type of loud that if an intruder hears it they ought to be running. It's the type of loud that if you place it outside your bedroom it's waking you up (unless you sleep like a rock).-You can plug it in-Battery backup-Cons:-Comes with a wall mount that can be drilled, or mounted with double-sided tape. I prefer a device that allows for mounting that at the outlet, similar to some echo devices, unfortunately one is not available.-A specific siren triggers when the device is touched. It doesn't last long, but it can get annoying if accidently touched.-The LED isn't very bright. I would say it's negligible and would not deter any intruder.Overall, I like this siren. Works for my needs.

I've been getting into home automation more and more lately after a couple small projects solved some annoying quality of life issues for us. It occurred to me I could get a "poor man's alarm system" with this product, and I did exactly that.I have a few other Zooz products which I've been happy with, so I've built up a little bit of "brand trust" with them. I much prefer the Z-Wave technology (over Zigbee and WiFi) for the fact that it uses a lesser-used 900MHz frequency spectrum and is also a "certified" platform. I could have solved the same problem with Zigbee much cheaper, but I just like Z-Wave more.I integrated these with Z-Wave JS on the Home Assistant platform. Integration was super simple and detection is sub-second fast. I then installed them on my two primary doors. I had to get a little "creative" on one of my two doors due to highly limited inside mounting locations, but found a good place after working the problem. I attached the sensor side with sticky velcro, to allow easy battery replacement. I used the provided sticky-tape to mount the magnet, but quickly upgraded to the provided screws after the magnet fell off shortly after install.The sensor is properly sized, though I'd prefer this tech to be even smaller. I definitely don't think it's "too big" for a hall sensor. I'm still on my first battery with these, but I'd generally expect "acceptable" battery life with the infrequency of operation. (If I have complaints, I'll update this review.) They use a CR2023 coin battery, which is easily acquired almost anywhere.In Home Assistant, the platform enumerates open/closed (on/off) status, battery level, low battery, ping and node status. Ping doesn't appear to do much, but all the others are helpful. My automation rules are fairly simple. When we are away and the door opens (sensor on), send an emergency level notification to our phones. I might get a bit "fancier" at some point, but I'm happy for a dirt-cheap, non-cloud, non-subscription alarm system. Combined with my external surveillance and other secret sauce, this was an excellent addition to my DIY home security that seriously rivals any commercial system you could buy.Even though these sensors are a bit on the "spendy" side for a basic hall sensor, I feel it's within an acceptable price range since I got everything I wanted. Considering it's Z-Wave, well sized and provides me with immense security value, I won't think twice about spending "twice as much" when compared to competing technologies. Assuming these hold up, I might buy a couple more. I'm thinking "freezer open" and "fridge open" applications, possibly others as well.Edit: Added quite a few of these now. I've automated my thermostat to turn down if any windows are open, preventing my furnace from trying to heat the outdoors. I also automated the lighting in my crawl space when the access hatch is open. Battery life depends on usage. My front door sensor goes the quickest (~8-10 months), since it's used the most, but on others I'm seeing 1+ year on the CR2023. Solid sensor, would buy more if needed.

20250411 I still like these sensors, but I wish there was a two-magnet version or a way to purchase extra magnets. I like to partially open some windows at night, and another magnet would let me do that and then alert me if the window was opened further.I like the way these sensors blend in. Now, if the battery life is good then we are set.

So this is working so far with HA, but when I initially set it up it always showed OPEN. No matter what I did it wouldn't change, so I read the reviews and saw someone else that changed the magnet. I grabbed a long neodymium magnet and stuck that on my mailbox and it started working!I don't know what's wrong with the included magnet but if you are having the same issue try another magnet with the sensor.

So in our house I have ancient door and window sensors and motion sensors connected to a Honeywell Alarm System where I have not replaced the batteries in 10 years. I am serious. Yes, those use CR123As which have far more capacity than a CR2032 (6x). But still. My other Z-Wave devices with CR123As will last 6 months to a year. This Zooz device is on our front gate, where it opens and closes maybe 4 times per day, but the Honeywell and other Z-Wave sensors send out data maybe 10-20 times per day. The battery level as reported by the device has been erratic, but right now (June 16th) it is reported as 55%, and the battery was installed on June 12, 4 days ago. I've attached the battery level graph that Home Assistant is reporting.Also, the waterproof case you can buy for this was not. The o-ring is too small and I could never get it to seal. It would rain and then the sensor would stop reporting "Open" until I dried it out for a few hours. It really needs to be a case that opens only at the bottom. My current attempt is to put it in a tiny zip lock bag with the opening at the bottom, and then mount that. So far so good with the zip lock - the sensor is working today after heavy rain last night.I only see this sensor as viable for a situation where the door or window just about never opens and it is mounted indoors.

These are much smaller than I expected. That is always a good thing when attaching sensors. I attached it to the sliding door. Now when the grandkids leave the sliding door open, the AC also shuts off after 5 minutes. I don't have to yell, "Close the door!" instead I can go back to yelling, "Get off my lawn." Or "Get Papa a beer". The device works fine, was easy to get connected to my hubitat, and all is well.
