There was a comment in the other Harmony thread that Logitech released a firmware update on 12/22 that may have broken the integration (see link below). I would log a support ticket with ST and hopefully they can help you out. As of now, I’m not experiencing issues with Harmony/ST; but I only use it to turn a couple lights off using the Harmony remote and I haven’t made any adjustments to either one (I don’t think my Harmony hubs were updated either).
