How exactly does the multisensor Quad meassure light? The attribute state returns values in percentage. Percentage of what? I can imagine 0% means complete darknes, but what is eg. 60% or 98%. And what is the minimum and maximum Lux values it can meassure?

You are correct 0% is darkest, 100% is brightest. Manual shows minimum at 20 lux and maximum 90 lux, see attached.

Thank you Alberto. Sorry I oversaw this information in the manual. This means that the quad sensor is only meant for indoor light measurement as 90 lux equals less than a "Very dark overcast day" according til Wikipedia.

Yes indeed, pretty much all zwave luminance/motion sensors I have seen are for indoors use. The only one I know it has IP rating is the GEN5 AEOTEC multisensor.

If you need a bit more range you can go to Fibaro or Aeotec multisensor, however I have these QUAD also and they work pretty good for indoors and they are better with the battery. I know also Zipato has a new Fibaro like multisensor but I don't have any experience with it.

I´ve done some research on this, as I wanted to find a good outdoor lux-sensor. I was very happy to find this:

This is, as far as I know the only lux sensor that can meassure real daylight. It´s lux range is 0-64.000. And it is made for outdoor mounting as well, and can operate in temperatures between -20 C to +60 C. 10 years battery! I don´t have any experience with this yes as I just got it, but it looks promising.

Thanks for sharing, I didn't know they have new versions of the strip. I knew about the door window sensors but not the others, will see how compatible are those with Zipato, please keep us updated. If it works OK I will buy a few too.
