Does anyone know how to do this? I can't find it anywhere via searching or Amazon. I already have the drop in feature working well within our house. They have numerous online examples about dropping in on contacts, such as, "Alexa, drop in on Grandma" but what if Grandma has 3 Echoes? If calling I seem to remember it rang them all, but I don't think we'd be able (or necessarily want) to open an intercom to all Echoes in the house.
Thanks
