Goodday, I am new at this forum, just installed my Homey and busy finding out the possibilities. I have one question: I have made a flow in where the hue sensor light value is below 100 the lights have to switch on. ( and a flow for the opposite ). This works but… Its takes around 2-3 minutes before the lights are switched on ( when i cover the sensor completely ) and it takes around 6 minutes to switch off again when the sensor has full daylight. I would like to have the action immediately. Is the normal? Thxs, Best regards, Jack ---

Can you share both flows so we can have a look at it. In my own case it works almost instantly, so it is solvable. Be aware, it is a motion sensor, so it reacts on a situation when motion is detected and will not react on only lux changing ---

With the Philips Hue Outdoor Sensor (Philips Hue, without the bridge app) I can set the measurement interval. However, I do not know if this is also possible with your sensor. ---

When the sensor reports every 5 minutes, should switching On and Off both be the same time? Can one set the measurement interval? There are two possibilities, Minimum report interval ( is set to 1 ) on the sensor and Maximum report interval ( is set to 60 ). I am using “Philips hue without the bridge” and a hue motion sensor. The settings appear to be stored but the switching takes time. I will attempt to blind the sensor and see whether i takes 5 minutes for ON and OFF, ( without moving the sensor, so without motion detected) ---

Situation is the same, after “blinding” the sensor it take 1-2 minutes to switch ON. It takes 5 minutes to switch Off. ---

I have the same behavior, but this is not a problem for me. These are the settings of the outdoor sensor: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/2/824b9c1ac6981a42e8f1f18a731d9aaf8006dfcf.jpeg) I don’t know how big the change must be before the lux value is reported. And this is the interval of the measurement of lux: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/d/1d18d9896fa4b240a27535f443034ab342c3799d.jpeg) Maybe you can find an answer or ask the developer in the relevant [thread](https://community.homey.app/t/app-philips-hue-zigbee/29734). ---

Just for information. On top: Philips Hue Outdoor Sensor Below: Xiaomi Light Sensor ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/1/813547acc6816a79c73a2dd0debccaeb51010100.jpeg) The sensors are installed in two different positions. This is one of the reasons for the different values. ---

Thanks, very interesting, indeed de Philips “polls” every 5 minutes, while the Xiaomi seems te poll every minute. Altering intervals changes the setting in the App, but do not alter the behavior. ---

The Xiaomi device is an actual light sensor, its whole purpose is to report the light level. The Hue device is a motion sensor with built-in light sensor, but that sensor is secondary. Xiaomi _motion_ sensors also have a light sensor built-in, but those report only when motion is detected as well. So if you’re looking for semi-realtime light level information, buy a dedicated light sensor. ---

The Xiaomi polls much often than 1 minute. It seems like as it polls life. I’m not sure if the statement from @robertklep is in generally correct, because the polling from a Fibaro (see screenshot from @apps) or NEO Coolcam is significantly faster, although they are primarily motion sensors. The polling interval of these motion sensors depends on the settings. ---

Thanks for sharing all the (new) insights. Since I cannot change the behavior of the Hue (motion) light sensor, I think its best to buy a dedicated light sensor! It would have been nice if the Hue sensor actually accepted changes in the setting ( to make it faster polling ). Great help! Jack. ---

@johan_bendz, is there a possibility to increase the polling interval of the Hue Motion Sensor? The settings „Min./Max report interval for lux“ seems not to work correctly. With settings „Min. = 1 s“ and „Max. = 60 s“ seems to have no influence of the polling interval. The polling interval seems to stay at approx. 5 Minutes.
