"Logitech Harmony Trigger" smartthings app is broken (resolved)

Hi @zraken that SmartApp is for after you’ve added your hubs to ST as a device, which is why you’re seeing no devices. Try going to the Marketplace -> Things -> Entertainment -> Remotes & Buttons -> Logitech -> Logitech Harmony Home Hub.

Based on the other thread it appears there might be an issue with ST discovering the Harmony Hubs at this time, but you would need to do this step before using the Harmony Trigger SmartApp.
