Outdoor luminance sensor

Questions & Help
1

I need an outdoor luminance sensor, that gives me a luminance reading at least once every 15. minute. Any recommendations on what to buy? I have my eyes on the Hue Outdoor sensor, but not sure if it only triggers the luminance when movement is triggered.

Hue-Outdoor > If the luminance of the sensor changes the luminance-value will sent to Homey regardless of the movement.

Sweet - thanks :+1:

Just FYI, Kim,

Almost all sensors @ Homey work with “something’s changed” updates, which saves battery as well.

What’s the point to send “20” every 15mins when the value stays 20 for several hours.

Good point, Peter. Have experienced though that my Ikea sensors doesn’t allways update on changes. But if the Hue sensor updates on changes that’s fine. Then I don’t need the update every 15 min. I just want to be sure to have a close to real time update to base my flows on.

I see. Sometimes the value did not change enough for the threshold.
For some sensors the minimal value change is adjustable.

2nd, there’s no real detection system for sensors “keeping quiet”.
It’s also possible they’re on the edge of their range, or your, or close neighbour’s, 2.4GHz wifi is interfering sometimes.

Here’s a nice script with which you can check the last update status of (certain) sensors:
