Sonoff Zigbee Motion sensor

[@nima-dev]

The device has a 1-minute buffer and won't send anything to the bridge as long as its state has not changed locally (to save battery). So, when you set the channel to turn off after 10 seconds, the motion sensor is still in the "occupied" state (not "clear" state) and won't update the bridge unless its status changes. So if you keep waving your hand in front of it (even for hours), it will keep its state in the "occupied" state and won't send any info to the bridge (hence no triggering).

[@relaymatik5984]

Same issue of my zigbee motion

[@OscarHanzely]

Yes this is called "cooling time" and all motion sensors have it. Some sensors like IKEA take 3 minutes before they can detect motion again. Some have it configurable. Its a hardware limitation most of the time.

[@eslamvet]

I knew that cooling time can be configured if you use smartthings hub. However i didn't test that myself. Any one does that?

[@peternikolob8450]

"Due to power consumption and power-saving considerations, there have some restrictions on the trigger That is: when SNZB-03 detects the movement, it will send a signal to ZBBridge If the device does not detect any movement for one minute, once the device triggered, it will send a signal to ZBBridge If any movement is detected within one minute, the device will not send a trigger to ZBBridge. And effective detection and trigger signals to ZBBridge will be delayed for one minute. It means the motion sensor works with one-minute intervals."

[@malakies999]

exactly what I was looking for.. was wandering why i couldnt turn off a light immediately i.e. 10 seconds after motion detected ceased. Anyway to get around this? I literally want it to turn on and off a light for 10-15 secs . A min is actually way overkill for this purpose.. Yep noob here. Thanks!

[@malakies999]

was wandering why couldnt i just have an automation that says IF lightglobe was on for more than 20 secs, turn it off, but that doesnt work for me! :(

[@darcioessa8966]

I just tested the sensor and on my testing the delay for “no motion” is 60s. So if you want more time fo the light or device that you want to control with motion for more time active i did a delay for “no motion” status of 15s and the lamp turned off in 1.15min so if you want more time just ad the time + 60s for the delay

[@dvirrotem1554]

Hey, how often I need to replace the battery?

[@dakkota27]

Can you set up 2 motion sensors on a staircase so they can act like a two way switch? For example: When I go down, first sensor turns on the light, when I rich down in the second sensor area, I would like the light stays on. Is this possible with scene settings in ZigBee bridge? Thanks and greetings from Cluj Napoca

[@csongorvarga]

Yes, with two sensors and a bridge. And set up a scene where either of two motion sensor is triggered a light comes on and goes off after e.g. 5 minutes. It will not be exactly 5 minutes after the last motion detection because subsequent motion detection does not restart the counter, but if you set it to a few minutes it would be enough anyway.

[@dakkota27]

@@csongorvarga Thank you very much for your fast answer You are doing a great job! Good luck with your channel !

[@mrfunkington]

Motion sets to inactive right away, but it can only detect motion every 2 or 3 minutes - I don't have the manual with me but it took me a while to understand how that works.

[@timknowlden]

I find the delays between sensing make this unusable? I can’t add the bridge to smart life so to control my Tuya devices I have to use IFTTT but there is a longer delay in then triggering lights etc to turn on.

[@csongorvarga]

I will make some tests. Since I am using it occasionally, the re-trigger delay does not appear to be that bad for me.

[@timknowlden]

Ah okay. I am using it to turn on a bathroom light which is powered using a WiFi socket in brilliant smart using IFTTT. It then on no motion turns the light off. However with constant motion it still doesn’t reactivate the ON command for the light

Yes, it should. I don't have a pir3, I did not test it myself.

@@csongorvarga Hi Csongor, thanks for your prompt reply. I already have BasicR3. I bought the RF Bridge and PIR3. I can create a scene : PIR3 -> BasicR3, it works perfectly when PIR3 detects motion. However, the RF Bridge will go to offiline unexpectedly after awhile, then I have to off and on again the RF Bridge.

sensor and the bridge have to be close physically and what is the distance?

[@neilcarroll7847]

I was looking forward to this video, how long have you tested this sensor for?

[@csongorvarga]

I have it up and running for a few weeks now, but I was away most of the time for holidays. So honestly not much actual testing just yet.

[@neilcarroll7847]

​@@csongorvarga Okay!! Does it turn off the light when you get away from the Sensor? as per Sonoff SNZB-03 This device has a mechanism. This product detects a moving object, then it will send an alert message, and it will go to sleep after 1 minute If the monitored object has been moving, the alarm information will be sent every 1 minute. This device detects the human body temperature, so if we create a scene for no movement then after a minute when there is no movement the light should go off!

[@eslamvet]

I wonder can it be used in bathroom, since it's humid area... is it IP protected? I knew no motion trigger time can be configured if you use Smathings hub. Is that correct? One final question, does it needs internet to keep working?

[@csongorvarga]

It is definitely not IP protected but if you can keep it off direct water it should be fine. I don't know about Smartthings never used that. Internet connection depends. If you are using it with the Sonoff app, you need internet connection. But if you have a local home automation solution that handles the logic locally do don't.

[@EsotericArctos]

What is the reset time like on this sensor? I got a Tuya Zigbee Motion Sensor and it is completely useless. It can take between 3 and 5 minutes to reset and trigger again.

[@csongorvarga]

I did not measure. But it looks like a few minutes at least.

[@EsotericArctos]

@@csongorvarga Darn, sounds similar to the Tuya one. I might be stuck goin with Philips Hue. Expensive, but they reset after 10 seconds.

[@neilcarroll7847]

​@@EsotericArctos Hi ​Brendan, will the Philips Hue sensor work with sonoff switch?

[@EsotericArctos]

@@neilcarroll7847 Unsure if it works with SonOff, but it works with deConz, Home Assistant ZHA, SmartThings, Hubitat and of course it's own hub. I am not sure how well third party devices work with SonOff. I have heard some mixed results. To pair the Hue Sensor with a third party bridge, you just delete it from the Hue Bridge, then use a pin in the RESET hole, holding it for about ten seconds (The LED on the Hue Sensor will go green). When you release it, the LED will flash green/orange and pair with a third party device. Same with the Hue Dimmer switches. Hue Globes need to be reset with a Dimmer switch, then they pair with third party hubs as well.

Have you been able to test the range and sensitivity? It’s said that it has a range of 6 meters. Did you have the same result in a normal temperature environment? Thanks for your review video!

I don't know how it works for the Roco Multimaus, but all Zigbee devices re-transmit the codes they receive. So any Zigbee device is a range extender as well.

[@jacopo.scarpellini]

Hi, how quick is it to react to a movement? I am currently using a 433MHz sensor, a Tasmotised Sonoff RF bridge and home assistant to turn on a light; there is about 1s delay between when the PIR detects the movement and the light turning on How quick is this?

[@csongorvarga]

The delay is probably a bit better, but there is some delay. Maybe 0.5s. But keep in mind that the most criticism this sensor gets, that in order to save battery, it goes to sleep for about 1 minute after motion is detected. So if you need multiple detections it will not do it.

[@jacopo.scarpellini]

@@csongorvarga yes, I've read that; I guess, as long as my light turns off after more than 1 minute (that's what it's set to), I should be ok

[@csongorvarga]

It is an indoor unit. But if it is protected from direct rain and sun, it would probably be ok to use outdoors.

Apparently it only scans for movement every 150 seconds!

[@gokhanyagdiran]

are you sure ? did you test it?

[@xanderc5097]

I would like to buy this zigbee bridge and would like to connect zigbee smoke detectors to it. Sonoff doesn’t mention smoke detectors in the available devices. Have you tried adding them anyways or have any idea if this would work?

[@csongorvarga]

I did not try, and I am not sure it will work. All I have tested is connecting other motion, door and temperature sensors to the bridge. Sonoff understands what a door sensor is, what a motion sensor is, even if it is coming from a non-Sonoff modell. This is why I think it will not do anything with the smoke sensor. The device will pair, but the app will not show any data, and you would not be able to use it in automation. In best case scenario it will act like a switch, so when smoke detected it will act as a switch has been turned on. But I really have no idea.

[@xanderc5097]

@@csongorvarga Thank you for your very fast reply. I guess I’ll have to look for another solution to receive push notifications on my phone when smoke is detected then. I know that Sonoff also makes a 433hZ bridge, so I could use that one. The reason I would have liked to use zigbee is that I found some really sleek looking zigbee smoke detectors and haven’t seen any with 433hZ frequency that look good.

[@csongorvarga]

@@xanderc5097 I am afraid it will not work. Zigbee devices do not send notifications, and in the eWelink scenes there is no possibility to add notification to the scene. You can use IFTTT to send you a notification, but for that you need the paid version of the Sonoff account. So they are not making it easy :(

[@xanderc5097]

@@csongorvarga at around 3:20 in the video, you can see a setting that says ‘’push notification’’ so if I connect a 433mhz smoke detector to the Sonoff 433mhz bridge, wouldn’t the app send out a push notification on my phone when the detector is triggered? Or does it not work?

@@xanderc5097 Yes, but for example the same option is not available for other Zigbee sensors. And I don't remember it at all for RF. So this is not a general feature which is available for all devices.

Hello, one question, if I install a ZigBee Bridge inside my house to connect a motion sensor inside a car, my doubt is that the car obviously when moving away will lose connection if I leave the sensor inside, when returning to the home will the sensor reconnect automatically? or the devices need to be paired again?

Yes it will work, it does not need to be paired again. It is like when you replace the battery once the old battery dies. It will just connect back to the gateway.
