Aqara P2 Matter over Thread - Cool Down Period Settings

Devices & Integrations Connected Things
1

I wrote a routine that states wait 1 minute after the last detection of motion on the P2 sensor and then turn off the light. I find that when the device is installed on the ST hub it operates with a cool down period of 55 to 60 seconds. As such, the turn off delay causes the light to stay on about 2 minutes following the last detection of motion.

The driver that was installed is the “Matter Sensor” SmartThings driver. The driver allows you to use the properties of Motion, Illuminance and Battery status in routines. I believe that the device is supposed to offer customizable settings however the ST driver does not provide access these settings. I was hoping to have such settings such as the retrigger interval and detection sensitivity. I attempted to select another driver but the app showed “no results found”. Is there any Custom Matter Sensor driver that I might try that will provide these additional settings?

So your routine perhaps says, “wait 1 minute after the sensor says there is no more motion and then turn off the light.”

In other works, are you looking for a driver that allows you to modify the default cool down period?

That is correct. I’d also like to be able to adjust the motion sensitivity. The sensor is set at “Medium” sensitivity as a default.

From everything I’ve seen so far, you can’t adjust the sensitivity at this time. Eventually, like some other sensors, you will be able to adjust it in the Aqara app, but aqara generally does not expose the sensitivity parameter to third parties.

Thank you.

I believe Matter as a whole doesn’t have a standardized mechanism for communicating device settings. So it’s not just an Aqara problem, but all Matter devices.

There’s a firmware update for the Aqara P2 motion sensor, version 1.0.3.0. While it doesn’t mention the cool down period, it allows to change the sensitivity, although probably not in SmartThings yet. (edit: in a screenshot of the Aqara app in that post you can change the cool down time, don’t know if it’s a standard Matter attribute or custom though).

I don’t have the device so I don’t know if you’ll be even able to update it with SmartThings, they’ve been radio silent for a couple years when it comes to Matter OTA updates. You can always use multi-admin with a virtual machine with Home Assistant to update it.

The Matter 1.4 sensitivity setting seems to be supported for some devices in stock drivers but not motion sensors.

Given it’s a WWST certified device, maybe @nayelyz or @Itati can suggest enabling the firmware update through SmartThings if it isn’t available and add support for the sensitivity settings in the drivers.

Thank you for the additional information.

I’ve received confirmation that Aqara uses the new standard HoldTime attribute to set the unoccupied delay for the motion sensor. (Edit: and the sensitivity attribute is CurrentSensitivityLevel , there are 3 levels)

It’s not supported by stock drivers either, so that’s another feature that would be welcome and it’s a basic setting for motion sensors along the aforementioned sensitivity. Tagging @nayelyz .

Of course, even if the drivers supported those attributes, SmartThings still needs to allow the Aqara P2 motion sensor to be updated via Matter OTA, haven’t received any answer in the Matter OTA post for years.
