This. Though a big-ish fan symbol (or heat, or whatever) on the paddle would be awesome too. I’ve been using color for this purpose: white paddles for most things, but almond paddles for (indoor) switches that control outdoor lights, and gray paddles for switches controlling exhaust fans. In this case, the color is meant to stand out.
For ceiling fans, I’ll eventually pick another color, but for now I use the HomeSeer ones (couldn’t wait for Project Windy City) and their LED indicators are on the wrong side, so they’re already visually distinct. (Hope Windy City comes out next year. The HomeSeers are good quality switches, don’t get me wrong, but Inovellis are good quality AND look better.
Even better, if I could order custom text with the symbol “:lightbulb: Front Hall Lights” on the paddle, I’d pay for that. I already do this with label-maker tape on the faceplate, but a professional-looking labeled paddle would be so much better! Maybe I should start a new “wishlist” thread.
