In prior installation of GE Zwave Dimmers I was able to turn off the little blue light by setting a new parameter in the switch (3, 1h, 2). This was no longer working when I redid my controller.
I found this little gem in an obscure place on the web. If you don’t want that little blue light on the GE/Jasco dimmer switch, for example in a bedroom, all you need to do is push Up, Up, Up, Down on the switch! I couldn’t believe it.
