KERUI Wireless PIR Motion Detector Indoor Suitable for Home Security Alarm System,P829

works great with my Sonoff RF bridge (that's been flashed with Tasmota)!then i continue to config the motion detector with HomeAssistant. it takes 3 AAA batteries. has dip switches to disable the LED light that's lit when motion is detected for discretion. has a physical on/off switch to save power if u dont need. also, this can be powered via micro USB. amazing!!!!

Works great. Battery life has been great. So far over 2 months battery still good. Only reason I’m giving it 4 and not 5 stars is the giant branding on it. Come on, looks crappy. I spray painted mine. Come on kerui. No one is going to walk into my house, look at the sensor and say, “hey, I’m gonna get me a kerui alarm system. This is a proper place to advertise the brand”

Seems to be working great after a few days. Really nice to have the micro USB power input option. The directions are a little confusing for the dip switch positions: The left switch (labeled on) delays 5 seconds in the ON position and 5 minutes on the OFF position. The right switch turns the LED on in the ON position and off in the OFF position. If you're using RTL_433, Kerui devices are device 68. Mine broadcasts at 433.920.

I use these for home automation installs. I use it in conjunction with a sonoff RF bridge to turn lights on automatically and for use as security motion sensors when the alarm is activated. They work far better than other brands I have tried, they pickup much better and seem to not be triggered by pets. Battery life is still good after 4 months.

I purchase the sirens to an addition to my security system W193, which is in my opinion the most advance today in the market and work with a $3 dollars a month with A pay as you go T Mobile sim card. The service this vendor provides is the best. All my security systems and misc components I purchase came on time and they provider all assistance I needed. This sirens is the best, easy to plug in in to W193 keypad and ready to go. I am very satisfy with the costumer service and quality of their products.

Just received 3 of these and 2/3 are defective. I'll return and order more because there aren't others I could find in this price range that will work with my very cheap DIGOO system. When I pulled the battery strip, the contact was weird and I could only sometimes get the red light to go on. Some strange contact problem with the battery I guess. One is installed and working thus far, I'll update if there's failure.

I was looking for an RF Sensor that could do both Open and Closed states and decided to try this one out. It works great with my Sonoff RF Bridge and I'm able to get it working just as well as a more expensive Zigbee one or Z-Wave one.

Batteries in Fuers sensors barely lasted 6months. Looks like the same battery is in this one. Other than that, good product.

Unit arrived with cut wire half way up positive cable. Clean brake. Difficult to trace because unit is completely sealed. Once opened found circuit brd attached to rear of unit. Trace from here to plug showed broken connection.

still working and really detects water instantly, way to go Kerui

Très satisfait !!

Just what I needed

Only send open command. Not close command.
