I'd very much like to know the same. Have just received a pack of six Flic and Hub LR for exactly this purpose. It really was not all that clear that this functionality doesn't exist yet.
Please provide an update as I've found this question being posted a fair amount. Feel pretty sad that I've just shelled out over $250 for a device that doesn't do the one thing I bought it for.
Look forward to hearing what Flic plan for this feature...
