I’ve been diving into the world of Home Assistant and Z-Wave devices lately, and it’s been an incredible journey. I wanted to share my experience in configuring three Aeotec ZW056 Z-Wave doorbell speakers to play alert tones simultaneously for various events. 
Initially, I found that Home Assistant only allowed the factory default doorbell MP3 file to play, which was a bit limiting. After some research, I discovered that the ZW056 has a configuration parameter for playing specific files. This led me to use the set_config_parameter service in my automations to trigger different alert tones. However, I faced a challenge where there was a 5-10 second delay between each speaker activation. 
After some troubleshooting, I realized that the delay was due to the controller waiting for each speaker to acknowledge the command before sending it to the next one. I explored ways to configure the controller to send commands to all speakers simultaneously but found that my setup with Hass.io limited some OpenZWave configurations. 
This experience taught me the importance of understanding device configurations and the value of community support. If anyone has tips on how to overcome this delay or has successfully configured multiple Z-Wave doorbell speakers, I’d love to hear your insights! 
It’s amazing how a little tweak can make such a big difference in home automation. Here’s to more learning and innovation in the world of smart homes!
