My 2 gang junction box had 2 switches, controlling a fan and its light. I got this fan from HD (Fan) which needed only one hot and a neutral to operate. The remote controls the fan's light. The other switch was wired to 4 new can-lights. The electrician did everything good.
Now, I want to replace the Light switch with a Z-wave dimmer : Dimmer
When I opened the junction box, the existing wiring confused me. The right switch controls lights and left one controls the fan. The new Dimmer needs 4 wires - Line (Hot), Neutral, Ground and Load.

I was able to swap the fan switch with a modern one and it worked fine. However, the Z-wave dimmer I couldn't make it work.
Can someone guide in simple words, how do I wire the dimmer to make it work ?
P.S. The neutral wire hanging down is something I haven't used yet. The dimmer switch said it needed a neutral, so I pulled one from existing lot.
P.S.S. I don't know how the new fan and can lights are wired. I cannot open it either. Sorry!
