Http command start music on wrong Chromecast audio

[sweup]

Hi

I'm a bit unsure weather this is a Domoticz problem or what..

Feature
To send music from a LMS server to a Chromecast Audio with the help of a Domoticz http command

Setup
I have a Qnap NAS running LMS in a container. In LMS I have the plugin CastBridge. In Domoticz i have a dummy switch that send a http command. I have two Chromecast audio, the Domoticz switch is supposed to trigger LMS to send a song to one of them.

Problem
Everything works except that the music is only played on one Chromecast device, even when i stated the IP adress for the "right" one.

I have followed this guide http://tutoriels.domotique-store.fr/con ... -http.html and using this http command in Domticz (right now the MAC adress but tried with IP adress also:
http://192.168.1.59:9000/status.html?p0 ... 9:D6:9B:40

In LMS i can choose any device and the music is played on correctly device. Any idea whats wrong? Ideally I would also like to send a command to play on both device.

Sry for bump, any advice?
