That's great. The one good reason to add Zigbee or Z-Wave devices to the mix is for sensors. There are a much wider array than are available from Lutron. Even motion sensors as the Lutron ones are quite large. I especially like the NYCE Zigbee sensors. They are small and work really well in stairwells at/near the foot of the stairs. If you do add battery sensors you need to add some wired repeaters to get a reliable system. I find Zigbee to be more reliable and easier to deal with especially with the current state of Z-Wave 700 series chipset.So far, Hubitat has been the most reliable Lutron plugin/controller I've used. Not a single missed action or command. I'm just using it for Lutron devices, so I haven't messed with Zwave or Zigbee.
