I just read the difference and decided not to mix and not to use the older 2476D’s either. Those just need to be retired. I will be looking for sales on 2477D’s or if someone has a good recommendation on Z-wave switches to replace standard 3-way switches, I’m all ears. Thanks!

I've mixed both types without any problems. A good use is to put one or more 2476D in a multigang box with a 2477D, to get the benefit of it's dual band capability.

I mix the two often, though over the years I have relegated the older switches to out of the way places like closets and the garage. Primarily since the ones I have are toggle and everything else is generally decora. Just make sure a dual band is somewhere in the vicinity and you should be OK. In the same box (like Guy mentioned) is ideal but probably anywhere nearby will help. I have one older switch, that consistently does not get the signal, that I plan to replace in an upcoming remodel. In the meantime, I have a dual band keypad in a tabletop encloser (that I use for testing and other things) and I plug it in near the "offending" switch. Problem solved.

For Z-wave, I like the Zooz line. Lots of options for switches and keypads. I have a few dozen installed of different types. Only issue with Z-wave is that they will respond to, but not control, a scene. So programs are required. Good Luck!
