Hi all,
This project I built allows you to emit simple audio buzzes via MQTT messages from a little speaker attached to your Raspberry Pi. Might come in handy in your automations for things like alarms, doorbell, audio notification or just general feedback that an automation has been triggered.
Give it a read and let me know what you think 
There’s more HA related content on my blog. I will link some more projects in separate discussion threads.
