Ah, couldn’t see your wallet from here 
OK, how about this:

Maybe with a piezo speaker it fits inside the Homey housing 
And this, translated from original Dutch post
(https://community.homey.app/t/71030/16?):
I built the wifi audio notifier tonight, from the Youtube clip
I installed the mqtt broker and client app on Homey for this
The experiences so far are:
- easy to build was done in no time.
- tts is worthless especially in Dutch
- I played an mp3 of a gong, that went pretty well
- the ringtone option works but sounds a bit 90s
- volume can be adjusted
- I think it shouldn’t be very difficult to add a multicolour led to the code to emulate the ledring function, for example.
Conclusion
Nice as an extra gong for doorbell or similar. Decent TTS is a loss → does anyone have an idea if this can be improved?
I actually hope to get the following things done in 1 device.
- separate device for sound/tts function
- led(ring) emulation
- low power consumption
- volume
