Vera controller and Google home

I have a Google home account on my Android which I’ve been using to control my Vera devices because I linked the accounts. 2 days ago I installed second generation light switches I told Google to sync devices I went back and it found the light switches but it says they’re offline not ready but they work fine I unlinked the accounts and re-link them same thing offline not ready but the other 20 devices still work by using voice commands. Any ideas why Google home thinks the new switches are offline is it because their second generation or is there a step by missing thank you I head of time for all your responses and help
