On that device, you can change the color, but not “on the fly.” It requires a reconfiguration of the firmware parameters, which requires physically manipulating the sensor, so couldn’t be used in the way you are imagining.
There are a number of other devices that you can use for a similar indicator, people most commonly use these to show whether the security mode is home or away. ( with these days of work at home and school at home, people are also looking for indicator lights for that purpose.)
if you’re interested in those take a look at the following.
The topic covers a number of different options, including making your own little light, light switches that have colored LEDs that you can control, a nightlight that switches color, etc.
Thanks for letting me know I don’t have control of the LED. Would have been a nice easy way to do an indicator.
I have seen that other thread, some interesting options but none that will quite work for what I need.
The closest things I’ve found so far is the Inovelli Red, I can control the indicator on it. But was hoping to not have to swap my light switch because it’s on a 3 way circuit and the switch I’d put it in doesn’t have the Line wire so I’d need to leave the other 3 way on permanently or get a special GE switch and do some rewiring.
