Z wave 4 way switch

Hello,

I need some help. Im installing a z wave switch 12724 with (2) add ons 12723. I know my wire that’s coming from the breaker. I tied in 2 red travelers. My 120v. On sector, other black wire on load. Pigtail my neutral, and my ground is connected. My 2 nd switch I have 2 blacks nut together. One red connected and pigtail my neutral. 3 rd switch. Red tied in traveler and pigtail my neutral. And black wire cap and ground connected.
I’m getting my blue light on my master switch 12724. But lights aren’t coming on. Can someone help please . Thanks in advance
