EcolinkIntelligent Technology Z-Wave Pet Immunity Motion Detector with Pet Immunity, White (PIRZWAVE2-ECO)

I am trying to save everyone some time by writing this.Here's the thing. With this Ecosense detector, there's three modes (set easily via jumper/pin): pet 1 (small pets), pet 2 (large pets), and test mode (which eliminates the 4 min delay).The thing is, **WHEN IT'S IN TEST MODE, THERE IS NO PET IMMUNITY** (yes, you heard right). You can't have pet immunity without the 4 min delay, at least on this unit anyways.Basically, how I see it, is if you don't want the 4 minute delay, just buy Samsung's Smartthings motion detectors since the battery will probably last longer (since this thing in Test mode will run down the battery). I know I might sound Pro-Samsung but I promise this is just the truth. However, if you DO want pet immunity, then buy this Ecosense detector, because the only way to do it with Samsung's are to place them high up where it won't "see" your pets. However, I feel the need to note that even with ST motion detectors, it's possible to place them higher to avoid pets, and you're gonna have to do that anyway with this one somewhat, but Ecosense's motion detectors pet immunity feature does work, but then you have the 4 min delay as long as pet immunity is on, and that's what you must understand. Basically, how I see it, this will cover a broader area and not detect pets. It's good to have both, I guess, for different areas.Some people who reviewed said the pet immunity feature doesn't work, but it definitely does (as long as it's not in Test mode), and I can tell because my cats definitely do not set it off in Pet 1 mode, although I haven't rigorously tested it yet.Even if this does alert me only every 4 minutes, at least I know that the detection isn't because of my cats, for example. I currently have the Ecosense in my living room where my cats will most likely to be, and it seems to be working out (In Test mode, though, they'll set it off everytime).I knew there'd be a drawback, and I guess this is it, although it could be a lot worse. Just wish I could have the best of both worlds with pet immunity and no 4 minute delay, but hey, this is good enough.I don't know why people said this was cheaper, also, since it was practically the same $30 as the Samsung Smartthings motion detectors (or any other).Installation is pretty much the same as with any Smartthings device, also, except inclusion mode had to be activated via the pinhole on back of unit (at least for me anyway), after activating inclusion mode on my SmartHub (obviously).Do NOT install the mounting bracket unless you KNOW exactly where you want it, also. You can't remove the unit or unscrew the screws from the bracket once it's mounted, and really can't even open the unit. Some people saw this as an upside, but I don't really see it as one (maybe if you have kids). I'd like to note that the piece that locks the motion detector in place could be broken off so the unit is removable, and no longer like this.Other than the 4 minute delay and pet immunity, it's pretty much the same as ST motion sensor. Not to sound negative, but I feel like Ecosense should advertise that it's an either/or choice between pet immunity and the 4 min delay. Still giving 5 stars because I feel like it does offer functionality (pet immunity) not offered by the ST's motion detector.

I have tried 7 connected motion sensors, including Aeon Labs Aeotec Multi-Sensor, Belkin WeMo Motion Sensor, Ecolink Motion Detector, Enerwave Z-wave Ceiling Mounted Motion Sensor, Philio 4-in-1 multi-sensor, Schlage Motion Sensor, and SmartThings SmartSense Motion Sensor.Aeon Labs Aeotec Multi-Sensor has multiple functions. However, the battery does not last long.Ecolink and Schlage are almost identical. (Their open/close sensors are almost identical. I assume that they share the same manufacturer.) The battery life is extremely good.Enerwave has a different design so that we can mount the sensor at a different location from others. For example, if I just want to the motion sensor to be triggered only when people are directly below the sensor. Unfortunately, the support is bad and thus it does not integrate well with other. While some people claimed it could be integrated with SmartThings. In reality, many people including me cannot make it work. Don’t buy this if you plan to integrate with SmartThings.SmartThings sensors are reasonable in terms of its form factor. However, the battery does not last long. It also has more false alarms than the Ecolink and Schlage motion sensor. There is a way to plug in USB power, but unfortunately AC power or USB power may not be available everywhere.Philio is a multi-sensor. Unfortunately, it may not be a good idea to have a PIR motion sensor and the open/close sensor on the same sensor. The open/close sensors are often mounted on the door or the window. If I have curtains or window blinds, then the PIR motion sensor will be blocked.WeMo motion sensor seems very stable. It is sensitive enough, but it did not generate false alarm in my experiment. Furthermore, it uses WiFi network, which is more stable than the Z-Wave or Zigbee network in my house. However, it must be AC powered. This limits where I can put it. Also, any further action/decision must be taken place in the cloud. It is not the best choice.Aeon, Ecolink, and Schlage allow users to adjust the sensitivity. However, there is no good feedback system for the user to adjust the sensitivities. It requires a lot of tries and errors.Personally, I would recommend different items for different purposes, depending on whether you have a good WiFi, Zigbee, or Z-wave network, whether you have a good AC power, whether it is easy for you to change battery, whether you want to have multiple functions, e.g., temperature or luminance sensor.In general, you don’t care of changing battery often, Aeon Multi-Sensor is a good choice. If you don’t really want to change the battery every six months, Ecolink or Schlage is better.
