I will investigate that and give it a go. The recent software update Logitech have done is fantastic, you could control hue lights before (which of course report back to vera) but the recent change means you can control the lights based on scene commands from the remote I.e dim the lights when selecting watch movie, so in that respect it kind of cuts out the need to run via vera to do that, especially as vera knows the state of the lights anyway.
I'm going to play with those options more, ideally would be nice to have vera still take charge of the lights one a "play movie" scene was selected from the remote but right as I could add in some nice time delays etc but for now it takes things closer. The harmony ultimate remote and the hub really is a fantastic but if kit especially as it lets anything running the app and the physical controller all sync, so you can turn stuff on with ipad or phone and then make changes or turn if off with the remote. Its one of those things that's just works and I can honesty say I'd not been without it now.
If I could get an infra red input into vera I could add those to the scenes in the harmony and have some very nice trigger of events, yes it would not be two way comms but no different to lightwave etc.
If a anyone wants a really good all in one remote the harmony is certainly worth a look, I think Logitech totally under sell some of its best features.
If they would publish api data for the hub it would be an even better piece of kit.
