There are lots of options: GE/Jasco, HomeSeer, Zooz, and Inovelli are popular in the Hubitat forums (where you can also find lots of similar questions asked--and answered). These all differ a bit in price and features: GE, in my opinion, is high on the latter and low on the former. :) (If you get those--or really anything--make sure it's Z-Wave Plus and not "classic" Z-Wave. Anything new should be, but GE in particular has a ton of old models that aren't, so if you buy used be aware. ) I'd take a look and see what features you want (multi-taps/scenes? notification LED? ability to disable local control for use with smart bulbs? ) and how much you're willing to pay.
