Adding Leviton zwave DMX1 dimmer

I bought the smartthings hub this week. I can’t add Leviton zwave DZMX1 dimmers… instructions say that light turns orange after pushing it 7 seconds … but it can only blink green…

Any help will be appreciated

Model DZMX1 sorry

Are you holding down the top or bottom part of the switch?

Has the device been used previously? If so, you should probably do a factory reset on it.

Leviton makes finding instructions difficult. There seem to be conflicting ones out there
