Dimming LED Lights

[Envirogreen]

Is there a way to set a minimum and maximum level for the dimming (I think its called trimming), so that there is no drop out when dimming the LED lights. 

 

I see that Radio RA has this ability and am hoping its something that folks have figured out how to implement using the ISY.

What kind of LED lights? What control module?

 

Dimming and brightening are certainly doable on the ISY platform.

I just experiment with various levels and set them as a local control or in programs so I know they are as low as they will go without dropping out or not illuminating in the first place.

 

I have one ensuite bathroom SwicthLinc that I wrote a short program to intercept the dimming signal and force the lowest level I have predetermined to be stay on.

 

I find the dimming rate too aggressive at the bottom end, with LEDs not being visually linear for dimming. They do very little at at the 100% down to about 40%, and then take off exponentially negative. This makes them harder to control at human desirable/useful dim levels.

builderb - larryllix describes  the exact issue that I was asking about.

 

larryllix - it sounds like there is no easy way to do this with ISY (e.g., max / min setting)...instead it would need to be programmed.

 

How does you code work?  I'm wondering if it replicates the trimming capability of the Radio RA.
