is this bluetooth only? i assume the bt radio is in the eisy. if so, the speakers will have to be close.
maybe i look for solutions that are more whole house than others. i have echos throughout the house - and sonos. another single use box in every room?
the advantage might be that setting up spoken responses are easier than echo routines. but it is possible to do and alexa's voice is pleasant. and i have always been impressed with the echo device sound quality (for a small box). but the sound quality from sonos amazes me. my todo list is to set up preferred speakers for echo devices to use sonos.
i love my eisy (or isy or whatever) but my approach to home automation is less reliant or it compared to years ago. With insteon, its a must have. for other things, its nice but not involved. i do not need the eisy for hvac control. echo handles that. same for televisions. (but being a nerd, i have the plugins)
i have migrated more to voice control - but only where i can avoid formulaic speech. "turn on the den left sofa lamp" is not something anyone will ever use. "turn on the lights" is something people will use. with echo (and the eisy) its possible to use 'turn on the lights' in any room and it works for each room. (when ud put in the synonym function of its portal, that was genius - it helps to reduce formulaic speak.)
i'd vote to integrate it into sonos. but i know that could be problematic. the best news is we now have a choice - bt speakers or echo routines.
