I too am looking for a reliable intercom system so that I can call up to different rooms upstairs for my kids and not have to yell at thre top of my lungs.
I pre ordered brightswitch but 2+ years later, still nothing from the indegogo project.
I recently bought 4 nucleus devices but returned them today to Lowes since they were unreliable and buggy. It may be a good solution in he future but not quite ready for prime time imho.
Any other ideas out there?
