Precise ZigBee Light Sensor?

Pedder

Is anyone aware of a ZigBee light sensor which is precise enough to distinguish between sunny and cloudy weather?

I found one from ELV (Order-No. 68-14 27 23), but which is only compatible for Homematic. And I would not like to implement a third standard (besides Homeduino and RaspBee) on my pimatic only for one sensor.

I only found motion or twilight sensors yet.

For detecting sunshine often temperature sensors are used. One black and one white. If they have the same temperature sun is not shining as it would heat up the black one more than the white one.

Hi @thex,
thanks for that smart work around. That sounds not bad and is cheap. I will think about 👍

Hi all,
an additional possibility, if someone tested it:

The Aquara Motion sensor also seems to deteced the light intensity.
Has someone tested if these measures are precise enough for a sunlight / cloud detection?
