I have two rooms, each with its own system. I created a separate handset for each (upstairs and downstairs). It all works great, but in order for me to switch handsets, I have to sync; it really shouldn't necessary to sync because I've not made any changes, I just want to select one or the other handset. Is there a way to do this without syncing?
You need to create a single handset for both rooms and have the landing page be the choice of which room. Then subsequent page be the page where you choose which activity to partake in that room. There is no way to switch handset otherwise because for each handset, only pertinent images are downloaded.
