Philio 4-in-1 Slim Z-Wave Multisensor Motion, Door/Window Contact, Light and Temperature Sensor. Works with EzloPlus, HomeAssistant, SmartThings and Other Z-Wave Hubs.

Cheap and works for me (with Home Assistant)
Wanted to integrate a z-wave motion sensor with my Home Assistant setup and this was the cheapest one I could find. Plus it also acts as a door and temperature sensor. It didn’t come with a manual and the manual you find online is a little janky. Luckily one of the first few comments mentioned the parameter to adjust to get it to report the way most people and automation systems would expect it to, which it report “motion”, then report “clear”. By default it seems to just sent motion reports and not send any “clear” reports. People tying it into systems other than Home Assistant may not know or be able to change the parameters to make the sensor binary to have it report both sides of the activity. It seems like this device may be meant for a more commercial application or install rather than consumers.Overall due to the lack of manual and confusing documentation found online I wanted to deduct 1 start but then I felt it deserved to have a star added back because of the good value you get with all the different sensors. After getting the first one figured out I went back and bought two more since the next closest device on Amazon that I could find was around twice the $18 price tag of this.

Incredible value for the money. 15 second recovery time for motion!
I bought some of these to replace my aging, huge, and unreliable Bosch motion/temperature sensors that took 4AA batteries and would spontaneously disconnect from my Hubitat about every 30 days or so. The only way to get them back online was to physically open them up, pull all 4 batteries, and then put everything back together. Very annoying when sensors are mounted on the ceilings.I’m REALLY impressed with these sensors so far. They paired instantly via z-wave with my Hubitat C8. There’s no manual in the box but just put your hub in pairing mode and hit the tamper button on the back of the sensor 3 times within 1.5 seconds to put it in pairing mode. Hit it 4 times and hold on the last press until the light goes red to perform a factory reset.There is a native driver on the Hubitat but you’ll want to replace that with a great user-written driver on GitHub. The native driver gives you zero functionality, most importantly no ability to adjust the temperature readings. The user driver gives you control over that along with just about every aspect of the sensor, including the ability to disable certain features. I have these mounted on the ceiling in various rooms to monitor for temperature and occupancy. I have zero use for the door function nor the illuminance function, so I just disabled those.This thing is tiny and very attractive on the outside. It includes a mounting bracket, tiny screws, and double-sided adhesive pads. There is no branding or lettering of any kind on the outside of the case so it’s very clean and unobtrusive. The entire base blinks red if you pull it off the wall and trips the tamper sensor. No beeping or other noise. It will report a tamper event to your hub via z-wave.The most impressive thing is the recovery time on the motion sensor. 15 SECONDS. Yes, it takes only 15 seconds to reset from a motion event before it will sense motion again. Very impressive!I can’t speak to battery life or long-term reliability yet but all in all this looks like a very well designed little unit. There’s no other sensor I’ve found that even comes close to this level of functionality at this price. To get anything remotely equivalent you’d have to pay at least double the price. I’ll update this review for battery life and reliability down the road.
