Nothing’s found using the homey.app store search bar, so it’s impossible to connect it as functioning thermostat with Homey atm.
AFAIK only simple, straight-forward devices, like lights and switches, are usable using the,generic z-wave driver.
However, it might be possible to add it as a SmartThings device to Homey (keeping the ST-hub operational)
