Just thought I’d share my setup to get multi-room audio using Bluetooth speakers. I have VLC running on a server and VLC Things running on ST. I already have Blue Iris running on a server so this is not a dedicated server just for ST. I also have a Bluetooth splitter and 2 Insignia plug-in speakers from Best Buy.
With this set up I’m able to have multi-room audio. This is no Sonos, but it’s cheap and it’s good enough for me for TTS announcements. If I want multi-room music all I have to do is run Pandora on my server.
A Bluetooth splitter (3.5mm to Bluetooth and supports 2 Bluetooth speakers) ($16.99)
Two of these Bluetooth plug-in speakers, one upstairs and one downstairs: ($19.99 each)
With this set up, if you want 4 or more speakers, all you have to do is get a 3.5mm analog splitter and plug it into your headphone jack (sorry iPhone 7) on your server, and get another Bluetooth splitter.
With Bluetooth, one downside I notice is that after 15 or so minutes they would power down to save energy, and when there’s a TTS announcement the first several seconds is cut off. I found a way around that by playing a silent wave file on repeat with Media Player.
