Re: Alternatives
There were a few perplexed faces that the music was exactly the same throughout the house.
That wasn't something I found too hard to achieve..
Appeasing the neighbours afterwards, however.... :)
When I was at school in the '80s friends had quite a bit of stuff around the house, built-in speakers that could be patched into other sources (so the lounge stereo could also be outputting to the garage, and/or the bedrooms etc, or you could have them off another source).
The idea has actually been around a very long time, even though the IoT generation seem to think they invented it :)
