Okay, So I’ve set up Fibaro Dimmer 2’s quite a few times before, I have 13 of them on the current installation. (generic z-wave installation)
I did some configuration last night and following such I sweep up ALL entities into a “Parking” view so that new “Unused” entities are easy to spot.
I went back to more configuration this morning and “Lo And Behold !” - I have a new entity !!!
sensor.fibaro_system_fgd212_dimmer_2_luminance
None of the other (identical) devices have this entity (a sensor at that) and it doesn’t make sense.
Why would a light have a luminence value (currently reading 176.0 lux, even though it’s off) ?
Why would it take approx. 6 months to appear ?
Why do none of the other devices exhibit the same sensor ?
I maintain entity naming notes (for consistency) and this does not appear in my notes for that device, so it’s ‘brand new’ to me.
A dimmer has no way of knowng what luminence it is producing (unless you enter a complex formula dependent on efficiency of the bulb’s power supply, linearisation of output to bulb output and therefore lux generated - yeah good luck with that) It doesnt even have lux (at what distance ?) at minimum and maximum - and let’s assume an “mx + c” from that
I know that ‘some’ devices generate new entities when they are populated e.g. “energy previous reading” (which seems obvious, but I still don;t know they announce the entity from day one and say “but the value is 0”)
Anyone having a clue - let me know
Thanks

The second method of including it seems easier to read
