multiple aqara gateways and custom mp3

[brjhaverkamp]

Hello all,

I am looking into using aqara devices to set up a home security system.
However, I require at least 3 places for a siren/alarm sound.
At the same time I would also like to reuse the system for a frontdoor bel and backdoor bel.
3 different sounds therefore. To keep it clean I would like to do it all with aqara material and domoticz.
I was thinking to use 3 gateways, since there is no separate speaker device in the aqara series.
Is this possible? The wiki states explicitely that custom mp3s are not doable with multiple gateways.
But I am not certain if that information is still correct.

Any feedback or experience is appreciated.

An other direction is the mqtt2zigbee gateway. I would have more flexibility in devices, but am a bit nervous about interoperability and support of the devices. Does anyone know a nice zigbee home siren that can play custom sounds? And preferably nice looking for on the wall:-)

Regards,

Bert
