If your garage has a button attached to it just add a Zen17 relay to the setup to make it smart.
For example 2 wires run from the garage door opener to a switch on the wall. Disconnect the 2 wires going to the wall switch and connect them to C and NO. Then take a new set of wires and connect them to S1 and C on the inputs of the Zen17. You will the be able to control it from the wall and from your Z-Wave hub.
TLDR: Yes there are new Z-Wave bulbs coming soon and they use the new Z-Wave 800 chips.
Whenever I want to stay up to date on Z-Wave Product Offerings there are (2) places I look. The first place is the FCCID website and the second place is Z-Wave Alliance Product Page.
On the FCC website I get pictures of the device, access to manual, and a list of the frequency a device uses. On the Z-Wave Alliance Product Page I get access to more specific Z-Wave information like wether or not the device uses an 800 series chip, it's association capabilities, it's supported command classes, and weather or not the device can act as a repeater.
After months of tracking products there is a pattern. Devices usually get FCC certified, then get Z-Wave certified then go on sale.
