Ceiling fan controllers with dim AND speed control recommendations

I have the King of Fans Ceiling Fan Controllers installed on four ceiling fans and I cannot get them to stay connected over Z-Wave. They worked perfectly when I was using a SmartThings hub. Now, I have to remove power for a while before they come back and that just isn’t a way to do things.

I am looking for a module with wall remote that will fit in a single gang electrical box that will control the fan and light and allow me to control them through HA. I don’t care what method, it just has to stay connected.

The fans have 120VAC in and then out on the controller is a common, fan and light wire for connectivity to the lights and the fan motor.
