The #smartHome will have about a dozen of these #RaspberryPi units throughout:

• Raspberry Pi 3B(+) - runs #DietPi and #Chromium to #homeAutomation dashboard, and #Snapcast for audio.
• Touchscreen provides access to control lights & audio
• Room speakers are powered by connected iQAudio #DigiAmp+

Hope is that built-in WiFi & Bluetooth may also be used for internal positioning of phones, #BluetoothLE devices etc. in future.
