Hello everybody,
Sorry for my limited english. French guy very happy to join this community.
I am a new comer on Home Assistant after several years on Domoticz.
I have just installed it on a Raspberry PI 5 with SSD. It is OK I configured a sonoff dongle E for Zigbee.
Integration done also with my Xiaomi hub and with my Rfxcom.
I have globally integrated my devices, camera and done my first automations and alerts.
I found Home Assistant fun and already enjoy the apps and the possibility to use it in my car through Android Auto also 
I have a first blocker after hours of reading website, forum, youtube, search on internet.
I have 2 issues :
1 - Use device and entities - change volume and select another sound
I have integrated in Rfxcom one doorbel model brand selectplus but cannot manage it as I would like and as I did on Domoticz. When I click on it nothing happen.
See below the entities integrated and the only way to launch I found :
My problem is that I would like to change the volume or select a different sound (15 are available see image).
I am not able to do so.
Do you have any idea please ? Can you help me ?
Thanks in advance for your help.
